1.0 INTRODUCTION
•The CBW series of scales provide an accurate, fast and versatile
series of general purpose weighing scales with counting, %
weighing and check-weighing functions.
•There are 2 series of scales - CBW scales which use kilograms
as the default unit and the CBWa range of scales have
changeable units from pounds to kilograms. The scales in these
series share the same functions except the CBWa series have
the ability to change the weighing units.
•There are 5 models in each series with capacities up to 45 kg /
100 lb.
•These all have stainless steel weighing platforms on an ABS base
assembly.
•All scales have sealed keypads with colour coded membrane
switches and the displays are large easy to read liquid crystal
type displays (LCD). The LCD’s are supplied with a backlight.
•
The scales include automatic zero tracking, audible alarm for pre-
set weights, automatic tare, pre-set tare, an accumulation facility
that allows the count to be stored and recalled as an accumulated
total and bi-directional RS-232 interface for communicating with a
PC or printer.

3.2 INSTALLATION OF CBW SERIES
•The CBW Series comes with a stainless steel platform packed
separately.
•Place the platform in the locating holes on the top cover.
•Do not press with excessive force as this could damage the load
cell inside.
•Level the scale by adjusting the four feet. The scale should be
adjusted such that the bubble in the spirit level is in the centre of
the level and the scale is supported by all four feet.
•Attach the power supply cable to the connector on the bottom of
the scale. Plug in the power supply module. The power switch is
located on the base on the right side of the scale.
•The scale will first display the model number (CBW 30- where 30
denotes the capacity of the scale in kg), followed by the revision
numbers (1.2-2.03 where 1.2 is the current hardware revision
number of the main circuit board and 2.03 is the current software
revision number). A self-test is followed next. At the end of the
self-test it will display “ZERO”, if the zero condition has been
achieved. A stable symbol and “GROSS” indicators are also
displayed.
4.0 KEY DESCRIPTIONS
KEYS PRIMARY FUNCTION SECONDARY FUNCTION
[Zero] Sets the zero point for all
subsequent weighing. The
display shows zero.
or [Enter] key when
setting parameters or other
functions.
[Tare] It tares the scale and stores the
current weight in memory as a
tare value, subtracts the tare
value from the weight and
shows the results. This is the
net weight. Entering a value
using the keypad will store that
value as the tare value.
A secondary function is
available to increment the active
digit when setting a value for
parameters or other functions.

[Limit] It sets the limits for check
weighing and allows setting of
either the low limit or the high
limit or both.
A secondary function
is available to move the active digit
to the right when setting values for
parameters or other functions.
[%]
It enters the percent weighing
function. Allows the weight,
unit weight, and count to be
seen when parts counting.
A secondary function is
available to move the active digit to
the left when setting values for
parameters or other functions.
[Func] This is used to select the
function of the scale. When
the scale is weighing, it will
select parts counting. When it
is not in the weighing mode it
will return the user to weighing.
A secondary function [C] is
available to act as a clear key
when setting values for parameters
or other functions.
[Print] It is used to print the results to
a PC or printer using the
optional RS-232 interface. It
also adds the value to the
accumulation memory if the
accumulation function is not
automatic.
A secondary function [ESC] is
used to return to normal operation
when the scale is in a parameter
setting mode.
[Units]
It is used to change the
weighing units of the display
from kilograms to grams and
back to kilograms for CBW
series.
For CBWa scales this key will
select kilograms, grams,
Pounds and Pounds/ounces
for the weighing unit, if
enabled. This should only be
done in gross weighing or at
zero.
None.

5.0 DISPLAYS
The LCD display will show a value and a unit to the right of the digits.
Other labels are TARE, GROSS, ZERO, (Stable) and (Low battery).
6.0
OPERATION
6.1 ZEROING THE DISPLAY
•You can press the [Zero/Enter] key at any time to set the zero
point from which all other weighing and counting is measured.
This will usually be necessary when the platform is empty. When
the zero point is obtained the display will show the indicator for
“ZERO”.
•The scale has an automatic re-zeroing function to account for
minor drifting or accumulation of material on the platform.
However you may need to press the [Zero/Enter] key to re-zero
the scale if small amounts of weight are still shown when the
platform is empty.

© Adam Equipment Company 2004

6.2 TARING
•Zero the scale by pressing the [Zero/Enter] key, if necessary. The
zero indicator will be on. Place a container on the platform, a value
for its weight will be displayed.
•Press the [Tare] key to tare the scale. The weight that was
displayed is stored as the tare value and it is subtracted from the
display, leaving zero on the display. The "TARE" indicator will be on
and the “GROSS” indicator will be off. As product is added only the
weight of the product will be shown. The scale could be tared a
second time if another type of product was to be added to the first
one. Again only the weight that is added after taring will be
displayed.
•When the container is removed a negative value will be shown. If
the scale was tared just before removing the container, this value is
the gross weight of the container plus all products those were
removed. The “ZERO”- indicator will also be on because the
platform is back to the same condition it was when the [Zero/Enter]
key was last pressed.
6.3 WEIGHING A SAMPLE
•To determine the weight of a sample, first tare an empty container if
used, then place the sample in the container. The display will show
the weight and the units of weight currently in use.
6.4 PERCENT WEIGHING
•The scale will allow a sample weight to be shown as 100%. Then
any other weight placed on the scale will be displayed as a
percentage of the original sample. For example is 350g is placed
on the scale and the [%] key is pressed the display will show
100.00%. Remove the 350g weight and place a 300g weight on the
scale. The display will show 85.71% as 300g is 85.71% of 350g.
•NOTE: The scale may jump by large numbers unexpectedly if small
weights are used to set the 100% level. For example, if only 23.5g
is placed on a scale with 0.5g increments and the scale is set to
100%, the display will show 100.00%, however a small change of
weight will cause the display to jump to 102.13% as one scale
division (0.5g) increase to 24.0g will be equivalent to an increase of
2.13%.
•Pressing [Func] will return the scale to weighing.

6.5 PARTS COUNTING
•Before beginning, tare the weight of any container that will be
used, leaving the empty container on the scale.
•Press the [Func] key to begin. The scale will show "" asking
for a sample size of 10 parts. Change the sample size by
pressing the [Tare/
]key. The display will cycle through the
options: 10, 20, 50, 100, 200 and back to 10.
•Place the number of samples on the scale. The number should
match the options for parts counting, i.e., 10, 20, 50, 100 or 200
pieces.
•Press the [Zero/Enter] key when the number matches the
number of parts used for the sample. As more weight is added,
the display will show the number of parts (pcs).
•Press the [%] key to display unit weight (g/pcs or lb/pcs), Total
weight (kg or lb) or the count (pcs).
•Press [Func] to return to normal weighing.
•‘lb’ will be shown on the CBWa scales when weighing unit is set
to pounds.
6.6 CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the
weight on the scale meets or exceeds the values stored in memory.
The memory holds values for a high limit and a low limit. Either or
both the limits can be used.
6.6.1 Setting up Check-weighing while weighing
•Press the [Limit] key. The display will show the current High Limit
with the left most digit flashing and the HI symbol on the left of the
display.
•To change the value shown press [%/
]and to select the digit to
change press [Limit/]. Use [Tare/]to increment the flashing
digit. When the desired value is shown press [Zero/Enter] to
accept the value. If you want to reset the value to zero, press the
[Func/C] key to clear the value.
•After pressing the [Zero/Enter] key the display will then show the
Low Limit, the “LO” symbol will be on to the left side of the
display. Enter the low limit in the same way the high limit was
entered.

11
•The limits are displayed in Kg.
•Pressing the [Zero/Enter] key will return the scale to weighing,
with the Check-weighing function enabled.
•When a weight is placed on the scale the arrows will show
whether the weight is above or below the limits and the beeper
will sound as described below.
BOTH LIMITS SET The display will show OK and the beeper will
sound when the weight is between the limits.
LOW LIMIT SET
HIGH LIMIT is set to zero.
The display will show OK and the beeper will
sound when the weight is less than the Low
Limit. Above the Low Limit the display will
show HI and the beeper will be off.
HIGH LIMIT SET LOW LIMIT is set to zero.
The display will show LO and the beeper will
be off when the weight is less than the High
Limit. Above the High Limit the display will
show OK and the beeper will be on.
BOTH LIMITS SET.
LOW IS SET
GREATER THAN
HIGH
The beeper will never sound and the display
will show LO if the weight is less that the Low
Limit and HI if the weight is greater than the
Low Limit.
6.6.2 Setting up Checkweighing while Parts Counting
•Checkweighing facility can be set up for Parts Counting by
entering values as Low and High Limits to be keyed in by the
user. The limits are displayed in PCS.
•Press [Func] to enter the Parts Counting mode. Press
[Zero/Enter] to fix a sample size. Press [Limit] and enter the
numeric values for high and low limits following the same
procedure as stated in the earlier section.
NOTE:
•The weight must be greater than 20 scale divisions for the check-
weighing to operate.
•To disable the Checkweighing function, enter zero into both limits
by pressing [Limit/] to recall the current settings.

•When the current limits are shown, press [Func/C] to clear the
settings and then press the [Zero/Enter] key to store the zero
values.
6.7 ACCUMULATED TOTAL
•The scale can be set to accumulate when a weight is added to
the scale automatically or manually by pressing [Print].
•See Section 7 on PARAMETERS for details. The accumulation
function is only available when weighing. It is disabled during
percent weighing or parts counting.
•The accumulated weights will be stored in the master unit of the
scale, i.e. kg or lbs.
•If at any time the weighing units are changed, the accumulated
data will be lost.
6.8 MANUAL ACCUMULATION
•When the scale is set to manual accumulation the weight
displayed will be stored in memory when the [Print] key is
pressed and the weight is stable.
•The display will show " " and then the total in memory for 2
seconds before returning to normal. If the optional RS-232
interface is installed the weight will be output to a printer or PC.
•Remove the weight, allowing the scale to return to zero and put a
second weight on. Press [Print], the display will show " "
and then show the new total.
•Continue until all weights have been added.
•To view the total in memory press the [Print] key when the scale
is at zero. The display will show the total number of items "
" and the total weight before returning to zero. The total will also
be printed via the RS-232 interface.
•To erase the memory, press [Print] to view the totals and then
press the [Func/C] key to clear the memory.

6.9 AUTOMATIC ACCUMULATION
•When the scale has been set to Automatic Accumulation the
value is stored in memory automatically.
•Add a weight to the scale. The beeper will sound when the scale
is stable indicating the value is accepted. Remove the weight.
•The display will show " " and then the total in the memory
before it returns to zero. Adding a second weight will repeat the
process.
•While the weight is on the scale, press the [Print] key to store the
value immediately. In this case the scale will not store the value
when the weight is removed. The total can be viewed as above.
•In all cases the scale must return to zero or a negative number
before another sample can be added to the memory.
•More products can be added and [Print] be pressed again. This
can continue for up to 99 entries, or until the capacity of the
display is exceeded.
7.0 PARAMETERS
The parameters can be chosen by the user to set the scale to:
•Display the weight in other increments of weight to minimise the
affects of vibration, wind or other environmental conditions.
•Control the back light on the display. It may be necessary to turn
the backlight off to maximise battery life.
