HANDHELD RF REMOTE INDICATOR for CELLSCALE
®
SECTION 1 – INTRODUCTION & ORIENTATION
INTRODUCTION
The Measurement Systems International MSI-9750A RF Remote Indicator is an accessory component of MSI's
CellScale
®
System. Combined with 1 or more CellScales, the 9750A provides complete control over all scale and
data functions. The 9750A serves as a remote terminal for any CellScale and has no internal measurement capa-
bility. One 9750A can read the output of many CellScales, and 1 CellScale can also provide data to many 9750's.
The backlit, alphanumeric graphic display provides precise, unambiguous indication of operating modes such as
Net, Gross, or Total. The 9750A can calibrate a CellScale remotely and provides a user interface to the advanced
features of the CellScale. The CellScale system is digitally calibrated from either the 3750CS Indicator, a 9750A
Indicator, or with a terminal program hooked directly to the CellScale model 9000. The 9750A combined with a
CellScale is designed to meet or exceed the requirements of all regulatory agencies.

GENERAL INFORMATION
The 9750A is a versatile indicator capable of displaying many data items. As a member of the CellScale family
the 9750A does not stand alone. It is a slave device to a MSI-9000 CellScale. All data displayed on the 9750A is
received via RF from a master CellScale. Many menus in the 9750A depend on information from the CellScale.
Therefore, turn the CellScale on before using the 9750A.
Due to the high data rates in the CellScale system menus usually respond instantly. However there are times
when the CellScale is busy and it will not “service” the 9750A instantly in all circumstances. At these times you
may see the word “Pending” or dashes, or data placeholders which will indicate the CellScale has not yet sent
the required information. Weight displays have priority and are sent before all text strings are updated (such as
channel name, ID name, etc.).
The majority of CellScale installations have only a single scale input. In this case the Multiple Display modes
are not needed. However, even with only a single scale input, Math Channels are available which can be applied
for specialized applications.
MANUAL & 9750A CONVENTIONS
1) Keys used in operations are printed in
BLUE
and capitalized. Numeric keys are bracketed (e.g.
[5]
).
2) Setup procedures are usually shown with the shortcut method of reaching the menu. All menus can also be
reached through the “Setup Select Menu”. Use the
[7]
key to see all available menu choices.
3) Screen shots are shown for example. Many screens provide additional information to orient the user to the
scale channel, or ID, or selections made. For example, the Function Key Setup menu will show you the current
selection for each key. When you change the function, the previous menu changes to refl ect your choice.
4) If a function key does not work, it is probably because the CellScale is not setup to support the key. For
example, if only one channel is defi ned in the CellScale, pressing the
CHANNEL
key will have no effect.
This also applies to the
ADDRESS
key. If only one Network has been defi ned, the
ADDRESS
key has no
other Network to log onto.
5) Menu Titles are shown at the top of the LCD screen and are fully capitalized.
6) When space permits, selected parameters are shown at the right side fully capitalized.
7) Submenus with multiple choices use a highlighted arrow “
4
” to indicate current choice(s).
8) When in menus, the
ESC
key (same as
SETUP
) drops back one menu level.
9) When in Setup Menus, the
DISPLAY
key returns you directly to the Weight Display (Exit mode).
10) Cursor Keys (alternate functions of F1, F2, F5 and F6) only function in menus. Use the DOWN (
v
) cursor
key to enable the cursors then use the UP (
^
) or DOWN (
v
) cursor to select line items. Use,
ENTER
, LEFT
(
<
), or RIGHT (
>
) cursor keys to rotate through menu choices or select the associated submenu.
11) If a submenu is associated with a menu choice, either highlight the menu choice with the cursor keys and
press
ENTER
, or press the numbered key corresponding to the desired menu item.
12) If a menu applies to any channel, pressing the
CHANNEL
key will select the next channel in the CellScale’s
scan list.
13) If a menu applies to any ID, pressing the
ID
key will select the next ID in the CellScale’s ID list.
14) To input, for example, an ‘E’, fi rst use the
ALPHA
key to change to alpha mode, then press
[2]
twice. If you
need two ‘E’s, pause briefl y until the display cursor has moved to the next position, then press
[2]
twice.
15) In single display modes, pressing the
ENTER
key highlights the whole display to indicate the next press of
a Function key will use the alternate mode (Enter-Function Key).

UNIT SETUP
The 9750A is simple to setup and use. If there are no peripheral devices such as a printer or bar code scanner,
setup consists of charging the battery, and setting the modem controls to talk to a 9000 CellScale.
BATTERY
The 9750A uses a high capacity Nickel Metal Hydride Rechargeable battery pack. The battery pack will power
the 9750A for up to 8 hours depending mainly on how much the LCD backlight is on. This is a custom battery
pack with over-temp and over-current protection designed for fast charging that must be replaced with MSI P/N
12431. The battery pack should last over 500 charge cycles. NiMH batteries do not suffer from memory effects
and can be charged at any time in the discharge cycle. NiMH batteries do have a fairly high self-discharge rate,
so if the unit is unplugged and idle for a long period of time, the batteries will require charging.
The 9750A LCD will display a low battery warning when there is about a half hour to an hour (depends on back-
light and battery age) of operating time remaining.
REPLACING THE BATTERY
The 9750A is shipped with the battery pre installed. When the battery needs replacing, remove the 6 screws on
the back panel to gain access to the NiMH battery. Gently pull out the battery cable from the interior of the case.
There is a single latch on the connector that must be pushed to separate the battery cable from the 9750A. After
plugging the new battery in, stuff the connector back into the case interior, then reseal the battery cover.
CHARGER ADAPTER
The 9750A battery charger is integral to the 9750A. Input power can any source of 12-24VDC with a minimum
of 20 watts of power. MSI provides two charger sources: 1) Universal AC power: Operates from 86 to 265 VAC
45 to 440 Hz. 2) Vehicle Power: Works with vehicles with 12-24 VDC battery systems (cigarette lighter adapter).
The maximum drain on the power source is 20 watts, but this amount of drain is brief. The source current tapers
down as the battery charges. For 12V systems the maximum drain is about 1.5 amps. A 5A fuse is suffi cient to
protect the vehicle electrical system while still providing enough peak power to charge the battery. The MSI
Cigarette Lighter Adapter (MSI P/N 12674) is internally fused with a 5A fuse.
CHARGING THE BATTERY
Turn off the 9750A. Plug in the Charger Adapter in the charge port. Charging will take up to 2 hours depending
on how much the battery was discharged. The 9750A has a charge status indicator on the front panel. The charger
is in fast charge mode when the light is Red. When the light turns Green, the 9750A is ready for use.
Charge Indicator
Off External Power Not Present
Blinking Red/Grn Charge Pending. Either the battery temperature is too high, or the cell voltage is below what
is safe to fast charge. The battery is trickle charged until these conditions are cleared.
Steady Red Fast Charge in progress.
Green Fast Charge Completed. Charger enters pulse phase charge top off. You can use the system
as soon as the green light is on. However, maximum charge capacity is reached about 30
minutes after the light turns green. The Green light will pulse often while in top off phase,
less often during maintenance phases.
When the battery is new, charge the battery for at least 2 hours initially. Then unplug the
adapter, let it cool for 1/2 hour, and then plug it back in. This will initiate another fast
charge cycle that should only last a short time if the battery is functioning properly.
The internal charger is a multi-stage charger. The external adapter can be left plugged in indefi nitely. It will
continually pulse charge the battery preventing self discharge and keeping the battery topped off. If the 9750A is
used sporadically, MSI recommends leaving the adapter plugged in while the system is idle.
Do not operate the 9750A with the adapter plugged in. The charger will not charge the internal battery. To ensure fully charging the
battery, turn the 9750A off, remove the power plug, then plug it back in.

SECTION 2 – RF SCALE COMMUNICATIONS
The 9750A is a component of the MSI CellScale System. The CellScale system uses frequency hopping
spread-spectrum RF Modem technology transmitting in the 2.4 GHz ISM band.
RF Modems have been problematic as the RF bands are very hostile, corrupted by noise, path loss and inter-
fering transmission from other radios. Even in a pure interference-free environment, radio performance faces
serious degradation through a phenomenon known as multipath fading, a problem particularly prevalent for
indoor installations. Multipath fading results when two or more refl ected rays of the transmitted signal arrive
at the receiving antenna with opposing phase, thereby partially or completely cancelling the desired signal.
Spread spectrum reduces the vulnerability of a radio system to both interference from jammers and multipath
fading by distributing the transmitted signal over a larger region of the frequency band than would otherwise
be necessary to send the information. This allows the signal to be reconstructed even though part of it may be
lost or corrupted in transit.
Spectrum has been set aside at 2.4 GHz in most countries for the purpose of allowing compliant spread spec-
trum systems to operate freely without the requirement of a site license. In the USA, there are absolutely no
site licensing requirements. The CellScale system is also programmable for use in most European countries.
Please contact MSI for worldwide compliance information.
FCC STATEMENT
FCC ID: HSW-2450M
Note: This unit has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interfer-
ence to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference
at their expense.
NETWORK DESCRIPTION
The CellScale system uses frequency hopping which is produced by transmitting the data signal as usual, but
varying the carrier frequency rapidly according to a pseudo-random pattern over a broad range of channels, in
this case 86 discreet frequencies. These 86 frequencies are combined in different “hopping patterns” to provide 64
(0-63) separate networks. The CellScale network uses a ‘Star’ network topology. One unit, usually the CellScale,
is designated a ‘Master’. The Master transmits a sync pulse on a regular basis, providing synchronization of all
remotes in the designated Network. Thus it forms the center of a cell. MSI provides three products capable of
being the master unit: the CellScale, the 9300 Crane Scale, or the 6260 Trans-Weigh CS Crane Scale. Up to 16
remotes can access the master unit. Current MSI provided remote devices include the 3750CS Indicator, the 9750A
Handheld Indicator, the 9850 Indicator, and the 9020 CellModem. Multiple remotes can coexist on one network,
or can be easily switched to other networks as required.
The CellScale system uses TDMA (Time Division Multiple Access) to arbitrate between multiple remotes. Each
remote is assigned a specifi c time slot thus guaranteeing data throughput. The CellScale network uses a ‘Star’
network topology. One unit, usually the CellScale, is designated a ‘Master’. The Master transmits a sync pulse on
a regular basis, providing synchronization of all remotes in the designated Network. MSI provides fi ve products
capable of being the master unit: the CellScale, the Smart CellModem 9000 (not 9020), the MSI-9260 ruggedized
Crane Scale, the MSI-9300 Porta-Weigh+ Crane Scale (with local display), or the MSI-6260CS Trans-Weigh CS
Crane Scale. Up to 15 slaves can access the master unit. The 9750A is always a ‘Slave’. Multiple 9750A units
can coexist on one network, or can be easily switched to other networks as required.
For more on setting up CellScale networks, please refer to the MSI-9000 CellScale User Guide.
ANTENNA
The 9750A uses a built in “Patch” antenna with no external visible element. The patch is located in the end of the
9750A above the display. In most installed CellScale networks, the patch antenna is essentially omnidirectional.
However, in systems where the 9750A is reaching the limits of transmission range, the 9750A will achieve better
range by pointing it toward the master CellScale’s antenna.

RF NETWORK SETUP
The 9750A is a RF Modem connected device. The RF Modem requires setup to connect to one or more CellScales.
The 9750A stores information for all 64 possible networks. Each network setting can be modifi ed with the “Modem
Settings Menu”.
[1]
NETWORK ADDRESS – Sets the primary network
address number. Set this number to match the Network
number of the CellScale master the 9750A must com-
municate to. Ranges from 0 to 63.
[2]
CS ADDRESS – Sets the primary master CellScale ID
number. This number must match the Source Address
number of the primary master CellScale. Ranges from
5 (default) to 251. This number is usually 5.
[3]
MY ADDRESS – Any 9750A unit in a given Network
must have a unique ID number. Enter up to three digits
to designate the 9750A ID number. Ranges from 5 to
251. Make sure no other devices have this same number.
Other devices that must have unique numbers are 9020
Modems, 3750CS Indicators, and 9300 and/or 6260CS
crane scales used as slave units.
[4]
TRANSMIT POWER – Sets the RF power level between
10 mW (Lo), 63 mW (Med), and 250 mW (Hi). In most
applications power should be set to High. Reduced
energy can reduce the size of the coverage / interfer-
ence zone which may be desirable for multiple-network
applications. Always check for adequate range coverage
when using the Low setting. Only a minor improvement
in battery life (~10%) is achieved by using the Lo set-
ting.
[5]
TIMEOUT – Sets the time in seconds (0-1800) that the
9750A will wait for data from the CellScale Master. The
display will blank out if no data is received within this
time period. MSI recommends at least a 10 second time
out period to handle small lapses in transmissions. The
system defaults to 10 seconds.
[6]
ADJUST MODEM – Advanced features settings of the
Modem. See “ADJUST MODEM MENU” on the fol-
lowing page. This line also shows the fi rmware version
of the RF Modem (v2.0x).
[7]
SAVE SETTINGS NOW – Commits the settings to the
Modems Memory. The Modem settings will be automati-
cally saved at power down if changed.
SCAN NETWORK – Setting the Scan Network ON places
the network in the list of addresses reached by pressing
the ADDRESS key. Setting the Scan Network OFF still
allows you to pre confi gure the network settings, but the
Network will not be in the list of available networks.

munications problems.
2) 802.11 Avoidance – The 9750As modem can be set to
minimize interference with 802.11b RF networks in
common use for computer networks. You must deter-
mine which band the 802.11b modem is operating on
and then select the corresponding band to avoid. The
second page also includes a setting making the cellscale
legal in France. The CellScale master must also have the
same setting. DO NOT change the setting in this menu
without corresponding changes in all CellScale devices
in the network.
3) Scan Network – When On, this feature adds Network
address information to a current networks list. If this
9750A is to be used on multiple networks, turn the
“Scan Network” “ON” every time you log onto another
network that you may want to go back to. Then using
the
ADDRESS
key, you can quickly scroll through all
stored networks.
4) Reranging – This feature sets the interval in which the
modem requests recomputation of the distance compen-
sation. The default is suitable for standard operation and
should not be altered.
The next line below Reranging gives a relative receive
signal strength. This value reports the relative signal
strength averaged over the last 10 hops. Larger values
indicate stronger signals.

TROUBLESHOOTING RF CONNECTION PROBLEMS
Most connection problems are caused by improperly set up RF Networks. Both the 9750A and the master CellScale
unit must have identical Network numbers. In addition, the CS Address must match on both units. If the Net-
work and/or CS Address of the CellScale is in question, you might have to connect a terminal to the CellScale to
determine its exact settings. See the CellScale manual for this procedure. Verify the 9750A settings are proper
by using the “CONFIGURE RF MODEM” procedure. Each slave device (9750As, 3750CS, and 9020s) must
have unique “My Address”.
A common cause of perceived problems is the “Phantom Network”. This occurs when there is a confl icting Net-
work within broadcast range. Multi-CellScale sites must be planned carefully so that there are never two master
CellScales on the same Network within range of each other. Since the CellScale can broadcast for miles with
good LOS (line of sight) conditions, this consideration is very important. If you suspect your 9750A has locked
on to a distant (Phantom) network, try switching both the master CellScale and the 9750A slave to another unused
Network. MSI advises avoiding Network #0 when possible, as this is the Modem default, and therefore most
likely to be found on units that were left in default settings.
Weight displays, but 9750A keys don’t work
This is a result of changing the CS Address in the slave 9750A so it no longer matches the master CellScale. The
modem is still registered by the master CellScale, but control codes are not received because the master assumes
the codes are intended for a different slave CellScale. Change the CS Address in the 9750A back to the number
that matches the master CellScale.
Unit goes in and out of communication
This is usually a result of being in or near an “RF Null” zone. Because of multiple echoes of signals there is
sometimes locations that are particularly problematic even for Frequency Hoppers. Usually moving the antenna
location even a small distance can clear up this kind of problem. Avoid placing the antenna up against large metal
walls. Concrete walls can also be problematic due to their high moisture content. The antenna should be at least
4 inches away from large metal or concrete surfaces. Mounting the antenna too close to a wall has the effect of
making the Antenna directional and can attenuate the output.
Range is Inadequate
Antenna placement is the most common cause of poor range. Check that the RF power level of the master and
slave units is on “High”. Radio signals in nearby bands that have signifi cant power can also reduce range. Lon-
gest range will always be achieved by Line-of-sight (LOS) antenna placement. Any obstacle that interferes with
LOS will reduce the range. Signifi cant blocking is caused by metal buildings, solid concrete walls, and any other
object that has fairly high electrical conductance. Raising the master antenna higher can help. Just moving the
relative antenna placement a short distance might fi nd an RF “path” that will improve distance. The CellScale
can sometimes take advantage of refl ecting surfaces to get around obstacles. CellScale device antennas should
always be placed in vertical polarization; that is the shaft of the antenna should be perpendicular to the earth,
not parallel. It is OK to mount the Antenna upside down. This is a good solution when an antenna is mounted on
the ceiling for communication with CellScale components in the building. The 9750A internal antenna is mildly
directional. Aim the end of the 9750A towards the CellScale master for longest range. In short range applications
(LOS and <500 feet) the 9750A is essentially omni-directional.
Some CellScale master units can take advantage of higher gain antennas.Yagi Antennas can greatly improve the
range of a CellScale system when installed on the master CellScale. These multi-element antennas are highly
directional and must be aimed towards the 9750A area of operation.
The CellScale system is designed using state of the art RF Modems. However there will be conditions and envi-
ronments where communication of telemetry is sporadic or impossible. Jamming of FHSS systems is diffi cult,
but not impossible. Bear in mind that the most likely source of jamming will be other CellScale systems on the
same network, within transmission range. The new breed of wireless phones (not Cell Phones) operating in the
2.4GHz bands will not jam a CellScale. However the CellScale may be received on the wireless phone and will
sound like a background ticking noise. Standard Cell Phones do not operate in the same bands as the CellScale and
will not interfere with CellScale components. However, a Cell Phone repeater tower nearby might have enough
out of band interference to reduce the range of CellScale equipment.

1) Place the 9750A in close proximity of the master CellScale unit. Make sure communications are good
(weight is on the display, all data types have been reported).
2) Press the function key programmed for “RF Site Testing”. The bottom right side of the display will read
“RF xx%”. The per cent reading indicates the ratio of successful transmissions. It will start low at fi rst,
then creep up. It should approach 100%, with an average reading of >96%.
If the reading does not achieve >96% within 1 minute try changing the CellScale Master device (MSI-9000, MSI-6260, MSI-9300, etc.) to a new network.
Usually the only thing that will interfere with a CellScale is another frequency hopping modem nearby. Also check your antenna connections on the
master.
3) Now start walking around the site with the 9750A. If the RF% reading starts down, stop and wait. Aim the
9750A towards the CellScale master and see if the RF% reading begins to rise again. If the display suddenly
reads “NETWORK”, you have lost communication. Return to the last place that communications were
working and wait for the 9750A to reconnect. In this way you can establish the range of adequate com-
munications, and note any areas with severe RF dropout. The location and height of the CellScale master
also plays a big part in range so be sure to run the site test with the CellScale in typical locations used in
your application.
4) Cancel the RF Site Test by pressing the function key again. If needed for some other function, reprogram
the function key.
RF SITE TESTING
The 9750A provides a means to check the effi ciency of RF transmissions using the RF Site Testing function.
Program a function key (use the procedure in Section 4) to “RF Site Testing” to run the test.
CELLSCALE NETWORK AUTO SCAN
For installations where multiple CellScale systems are present, the 9750A can scan every network and determine
if a CellScale master device is broadcasting. Found CellScales can be copied directly into the RF Scan List at the
end of the test. Turn on all CellScale masters (MSI-9000, 6260CS, 9300, etc.) that your 9750A will be used with.
Ensure that each CellScale master is on unique network addresses (see product User Guides).
1) Press
POWER
followed quickly by
ESC
.
It doesn’t matter if the 9750A is on or off.
2) Press

to start the scan. The 9750A will begin a progressive scan of all 64 (0-63) net-
works.
The scan can take as long as 15 minutes. If the backlight times out, press any number key to turn it back on.
3) Every CellScale master found will display along with its address. The end of the test will be indicated by
the display reading “ENTER Copy to Scan”.

MULTIPLE SCALE CHANNELS
Each CellScale is capable of hosting up to 32 independent scale inputs. Since any 9750A can communicate with
any CellScale, theoretically hundreds of scales can be controlled by a single 9750A. Because of the complexi-
ties of multiple channel setups, the 9750A is designed to access channels that have been previously setup in the
CellScale through its terminal interface or virtual meter interface.
Channels in the CellScale are organized by the A/D input channel followed by a Mux sub channel value. The
standard CellScale has two A/D inputs, but can be ordered with four A/D inputs with the addition of a second
A/D Converter module. Each A/D channel can be further divided by the use of external multiplexers into eight
additional inputs per channel, providing a total of up to 32 independent scale inputs. The channels are designated
like this:
Channel (A/D 1-4)
→
1-1
←
Sub channel (mux 1-8)
The channel will vary from 1-4 and the sub channel from 1-8. In addition the CellScale provides channel 5 for
slave CellScales, and channel 6 for math channels. Math Channels allow the user to add or subtract channels from
each other or perform other mathematical manipulations of the data. All calibration data for the 32 channels is
stored in the CellScale and is independent of the 9750A. Therefore any 9750A can receive calibrated data from
any CellScale provided the RF network is set up properly.
It should be noted that sub channels are useful even when the multiplexer option is not used. For example, chan-
nel 1-1 could be calibrated as a 1000 x 0.5 kg scale, and channel 1-2 as a 2000 x 1 kg scale, making a dual range
platform (of course this assumes the platform is capable of handling 2000 kg). This will work as long as the main
channel remains constant. So, in theory, 1 platform could be calibrated as 8 independent scales. This works because
the CellScale does not know or care if a Multiplexer is actually present. It treats the input as a separate scale.
The 9750A reads multiple channels by using the Scan list index. The “Scan list” is stored in the CellScale, with
up to 32 channels present in the list. The fi rst number in the scan list is called the Scan List Index number. The
CellScale can have up to 32 Scan List indices. A scan list can include “Math Channels” which provide a means
to digitally add the results of multiple scales.
When dealing with multiple channels it is recommended that you set up the display to always show either the
Channel Number or the Channel Name or both. This will help in identifying which scale you are observing.
SELECTING THE ACTIVE CHANNEL
Before standard scale functions are performed, you must select the “Active Channel”. The “Active Channel” is the
channel that commands such as Zero, Tare, Total, etc. will be performed on. On single channel display screens,
the channel shown is the active channel. On Multiple channel displays, you must highlight the desired channel.
This is done with the Cursor Keys. Once highlighted you can perform all the standard scale functions (except
Total and View Total, these only work from the single channel display). You can also switch to the single channel
display by pressing the
DISPLAY
key.
See the “DISPLAY MODE SETUP” section 7 for information on multiple and single channel weight display modes. For more information on Scan Lists and multiple
scale channels, please refer to the CellScale MSI-9000 Users Guide.

the case for MSI-6260CS, MSI-9300 Crane Scales, and other single load cell systems. However, even single load
cell systems can have math channels defi ned to add functionality.
For systems with multiple scales attached to any given CellScale the setup procedure is:
1) Program the CellScale Scan List as required (see the CellScale Manual). It is recommended that each channel
is assigned a channel name to aid in identifying the scale in various display modes.
2) Optional, but recommended so you can readily identify which scale you are monitoring and controlling

To Change Scale Channel Using the Channel Number (Single Channel Display)
Uses the CellScale’s Channel Number to determine which channel to display.
1) Using the numeric keys, input the number corresponding to the desired channel
number. Use the decimal point as the channel-subchannel separator.
This example finds channel 6-1, a math channel. If a requested channel does not exist in the scan list, this procedure

MULTI-CHANNEL SYSTEMS
In CellScale systems with multiple channels, you can choose to see more than one channel at a time (See Display
Setup in Section 7). In order to zero, tare, or totalize with channels in a multiple channel display, you must fi rst
select the channel to operate on. This is referred to as the “Active” channel, because this is the only channel that
any scale function can be performed on.
To Select the Active Channel (multi-channel display)
1) Highlight the channel you wish to make Active by pressing the UP (
^
) or DOWN (
v
) cursor keys.
2) Once highlighted you can Zero the channel, set and clear Tare, and switch between Net and Gross with the
NET/GROSS
key, just press the appropriate key. For Total, View Total, Statistics and other ID functions,
you must switch the display to the single channel display by pressing
DISPLAY
.
To Change a Channel in the Multi-Channel Display
1) Highlight the channel you wish to change by pressing the UP (
^
) or DOWN (
v
) cursor keys.
2) Once highlighted enter the scan list position (1-32) or the channel number (1-1 to 6-32 using the decimal
point for the sub channel entry). Then press
CHANNEL
.
The new channel replaces the previous channel. If the channel is already on the display in another location, both will display the same information.

Multi-Channel Page Display
When a multi-channel display mode is selected that shows fewer channels than are available from the CellScale,
the user can view all channels with the page mode.
Any channel can appear on any page by changing the preset channel using the “To Change Scale Channel...”
procedure. This allows a primary channel to show always, and secondary channels to change using the
ALPHA
key. This applies very well to the 3 channel preset display where one channel is large and the other 2 channels
are small.
To Change to the Next Page
Press the
ALPHA
key. The next group of channels appears. The action of the
ALPHA
key is circular, return-
ing to page 1 after the last page.
To Copy the Current Page
Sometimes it is advantageous to copy the current page and then make channel changes on the new page.
1) Press the
ENTER
key. The entire screen will reverse.
2) Press the
ALPHA
key. The new copied page will appear. Make modifi cations with the enter channel pro-
cedures as desired.
To Delete the Current Page
1) Press the
[0]
(SPACE)
key.
2) Press the
ALPHA
key. The current page will be deleted and the display will revert to the fi rst page.
The 9750A will not allow the deletion of the last remaining page.
To Move Around in Pages
If you have many preset pages, you can move directly to pages by number entry.
1) Enter the number corresponding to the page you wish to see.
2) Press the
ALPHA
key. The new page will appear.
1) In single channel mode, go to step 2. In multi-channel mode, highlight a channel
with the up (
^
) or down (
v
) cursor keys to make it active.
2) Press
ZERO
. The weight reading must be stable within the motion window for
the zero function to work. The display temporarily reads “ZEROING” and then
“ZEROED” after the CellScale acknowledges the command. The scale digits
display 0 (or 0.0 or 0.00, etc..). The backup memory in the CellScale stores the
zero reading, and can restore it even if power fails.
The “ZEROING” and “ZEROED” messages may not be displayed on every zero request if the CellScale responds
instantly, but the scale will zero.

To Zero
Zero Rules for Use:
1) Works in GROSS mode or NET mode. Zeroing while in Net mode will zero the gross weight causing the display
to show the negative Tare value.
2) The scale must be stable within the Motion window. The scale will not zero if the motion detect annunciator
is on. The CellScale will “remember” that it has a zero request for 2 seconds. If motion clears in that time,

the scale will zero.
3) The scale will accept a zero setting over the full Range of the scale (NTEP and other Legal-for-trade models may
have a limited zero range). Zero settings above 4% of full scale will subtract from the overall capacity of the scale.
For example if you zero out 100 lb. on a 1000 lb. scale the overall capacity of the scale will reduce to 900 lb. plus

TARE
Tare is typically used to zero out a known weight such as a packing container or pallet and display the load in
NET weight. A Tare value is entered in either of two ways:
1) PUSH BUTTON TARE – When the
TARE
key is pressed, the current weight is zeroed and Net Weight is
displayed.
2) KEYBOARD TARE – Using the numeric keys, the operator keys in the desired Tare Weight then presses the
TARE
Key.

To Clear Tare and Revert to Gross Mode
If the goal is to see the Gross Weight, use the Net/Gross key instead.

To Keyboard Tare
Tare - Rules for Use:
1) Only positive gross weight readings can be tared. Weight can be tared in both the NET and GROSS modes.
When in the NET mode, the TARE is not cumulative, all the weight is tared off (to Net zero).
2) The motion annunciator must be off. The weight reading must be stable.
3) Setting or changing the tare has no effect on the Gross zero setting.
4) Taring will reduce the apparent over range of the scale. For example, taring a 10 lb. container on a 60 lb.
scale, the scale will overload at a net weight of 50 lb. (60-10) plus any additional allowed overload (usually
~4% or 9d).
5) The scale stores the Tare value in the current ID Code memory until cleared. Each available ID Code can
store independent Tare values.
