3.2 INSTALLATION OF CBC-M SERIES
•The CBC-M Scales 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.
•Turn the power ON using the switch located on the right side
of the base.
•The scale will show the current software revision number in
the “Weight” display window (V3.06A where 3.06 indicates the
current software revision number and Aindicates that it is the
approved model).
•Next a self-test is performed. At the end of the self-test, it will
display “0” in all three displays, if the zero condition has been
achieved.

To set the upper limit for the number of items counted.
When this upper limit is exceeded the scale will sound
the beeper.
[Print] To print the accumulated totals to a PC or printer using
the RS-232 interface.
[Smpl] Used to input the number of items in a sample.
[U.Wt./Units]
Used to enter the weight of a sample manually.
[Tare] Tares the scale. 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 as the tare value.
[Zero] Sets the zero point for all subsequent weighing. It shows
zero.
5.0 DISPLAYS
The scales have three digital display windows. These are “Weight”,
“Unit Weight” and “Count”.
5.1 WEIGHT DISPLAY
It has 5-digit display to indicate the weight on the scale.
Arrows above symbols will indicate the following:

Net Weight Display, "Net"
Stability indicator, "Stable" or symbol as above.
Zero indicator, "Zero" or symbol 0

as above

5.2 UNIT WEIGHT DISPLAY
•This display will show the unit weight of a sample. This value is
either input by the user or computed by the scale. The unit of
measurement is kilograms on all CBC-M series.
•The arrow indicator will be seen above "Sample" or
symbol as above, when there is insufficient number of samples
to accurately determine the count.
•When the unit weight is not large enough to determine an
accurate count, the arrow indicator will be seen above "U.
Weight" or symbol as above.
•In both cases the scale continues to operate and the
indications are to alert the user for a potential problem.
•If a preset count has been stored the "Preset" or symbol
as above, will have an arrow above.
5.3 COUNT DISPLAY
•This display will show the number of items on the scale or the
value of the accumulated count. See the next section on
OPERATION.
•The arrow indicator will be seen above "Memory" when a value
has been entered into the memory.
6.0 OPERATION
6.1 ZEROING THE DISPLAY
•You can press the [Zero] key at any time to set the zero point
from which all other weighing and counting is measured. This
will usually be necessary only when the platform is empty.
When the zero point is obtained the “Weight” 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 [Zero] to re-zero the scale if
small amounts of weight are still shown when the platform is
empty.

6.2 TARING
•Zero the scale by pressing the [Zero] key if necessary. The
indicator above “Zero” 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 which is subtracted from
the display, leaving zero on the display. The indicator above
“Net” will be ON.
•As a 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 indicator above “Zero”
will also be ON because the platform is back to the same
condition as it was when the [Zero] key was pressed last.
6.3 PARTS COUNTING
6.3.1 Setting Unit Weight
In order to do parts counting it is necessary to know the average weight
of the items to be counted. This can be done by weighing a known
number of the items and letting the scale determine the average unit
weight or by manually inputting a known unit weight using the keypad.
A. Weighing a sample to determine the Unit Weight
To determine the average weight of the items to be counted, you
will need to place a known quantity of the items on the scale and
then to key in the number of items being weighed. The scale will
then divide the total weight by the number of items and display the
average unit weight. Press [CE] anytime to clear the unit weight.
•Zero the scale by pressing the [Zero] key if necessary. If a
container is to be used, place the container on the scale and
tare by pressing [Tare] as discussed earlier.

•Place a known quantity of items on the scale. After the
weight display is stable, enter the quantity of items using the
numeric keys and then press the [Smpl] key.
•The number of units will be displayed on the "Count" display
and the computed average weight will be shown on the "Unit
Weight" display.
•As more items are added to the scale, the weight and the
quantity will increase.
•If a quantity which is smaller than the sample is placed on
the scale, then the scale will automatically enhance the Unit
Weight by re-calculating it. To lock the Unit Weight and avoid
re-sampling, press [U. Wt./Units].
•If the scale is not stable, the calculation will not be
completed. If the weight is below zero, the “Count” display
will show negative count.
B. Entering a known Unit Weight
•If the unit weight is already known then it is possible to enter
that value using the keypad.
•Enter the value of the unit weight in grams, using the
numeric keys followed by pressing the [U. Wt./Units] key.
The "Unit Weight" display will show the value as it was
entered.
•The sample is then added to the scale and the weight will be
displayed as well as the quantity, based on the unit weight.
6.3.2 Counting more parts
•After the unit weight has been determined or entered, it is
possible to use the scale for parts counting. The scale can
be tared to account for the container weight as discussed in
the earlier section.
•After the scale is tared the items to be counted are added
and the "Count" display will show the number of items,
computed using the total weight and the unit weight.
•It is possible to increase the accuracy of the unit weight at

any time during the counting process by entering the count
displayed and then pressing the [Smpl] key. You must be
certain that the quantity displayed matches the quantity on
the scale before pressing the key. The unit weight can be
adjusted based upon a larger sample quantity. This will give
greater accuracy when counting larger sample sizes.
6.3.3 Automatic part weight updates
•At the time of computing the unit weight (see section 6.3.1A),
the scale will automatically update the unit weight when a
sample less than the sample already on the platform is
added. A beep will be heard when the value is updated. It is
wise to check the quantity is correct when the unit weight
has been updated automatically.
•This feature is turned off as soon as the number of items
added exceeds the count used as a sample.
6.3.4 Check-counting
•Check-counting is a procedure to cause an alarm to sound
when the number of items counted on the scale meets or
exceeds a number stored in the memory by using the [Pst]
key.
•The stored value is entered from the keyboard. Enter the
numeric value to be stored using the numeric keys. Then
press the [Pst] key to store the value.
•To clear the value from the memory and thereby turn off the
check-counting feature, enter the value "0" and press [Pst].
6.3.5 Manually Accumulated Totals
•The values (weight and count) shown on the display can be
added to the values in the memory by pressing the [M+] key.
The "Weight" display will show the total weight, the "Count"
display will show the total accumulated count and the "Unit
Weight" display shows the number of times, the items have
been added to the memory for accumulation. The values will
be displayed for 2 seconds before returning to normal.
•The scale must return to zero or a negative number, before
another sample can be added to the memory.
•More products can then be added and the [M+] key to be

11
pressed again. This can continue for up to 99 entries or until
the capacity of the “Weight” display is reached.
•To observe the total stored value, press the [MR] key. The
total will be displayed for 2 seconds.
•To clear the memory- first press [MR] to recall the totals
from memory and then press the [CE] key to clear all values
from the memory.
6.3.6 Automatic Accumulated Totals
•The scale can be set to automatically accumulate totals
when a weight is placed on the scale. This eliminates the
need to press the [M+] key to store values into the memory.
However the [M+] key is still active and can be pressed to
store the values immediately. In this case the values will not
be stored when the scale returns to zero.
•See the Section 8.0 on RS-232 Interface for details on how
to enable Automatic Accumulation.
7.0 PARAMETERS
The parameters are set to customise the scale to suit the weighing
applications. For CBC-M scales, it is necessary to enter a secure menu
using a password to set some parameters. To proceed with the setting
of these parameters, the security seal has to be broken.

9.0 BATTERY AND BACKLIGHT OPERATION
9.1 RECHARGEABLE BATTERY
•The scales can be operated from the battery, if desired. The
battery life is approximately 90 hours.
•When the battery needs charging the arrow above the low
battery symbol under the “Weight” display will turn on. The
battery should be charged as soon as the arrow is on. The
scale will still operate for about 10 minutes after which it will
automatically switch off to protect the battery.
•To charge the battery, simply plug the scale into the mains
and switch the mains power ON. The scale does not need to
be turned on.
•The battery should be charged for at least 12 hours for full
capacity.
•Just under the “Count” display is an LED to indicate the
status of battery charging. When the scale is plugged into
the mains power, the internal battery will be charged. If the
LED is green the battery is fully charged. If it is red, the
battery is nearly discharged and yellow indicates the battery
should be charged longer, preferably overnight.
•If the battery has not been used properly or it is used for a
number of years it may eventually fail to hold a full charge. If
the battery life becomes unacceptable then contact your
distributor or Adam Equipment.

11.0 CALIBRATION
The CBC-M approved scales are sealed to prevent unauthorised
calibration. Contact Adam Equipment or your supplier for more details.
11.1 CALIBRATION PROCEDURE
The calibration of the CBC-M scale is
accomplished by removing the label at
the base of the scale which covers a
hole through which the PCB can be
accessed. If your scale is not provided
with this hole, you need to break the
security seals and remove the top
cover to gain access to the circuit
boards inside. See the figure on the
security seal below.
WARNING: CALIBRATION OF THE SCALES MAY MAKE IT ILLEGAL TO USE
THE SCALES FOR SALES OF GOODS. CONTACT YOUR TRADING
STANDARDS OFFICE FOR FURTHER ASSISTANCE.
11.2 SECURITY SEALS
To seal the scale a lead-wire seal can
be used as shown below. The base has
a metal pin that protrudes through the
cover. The security seal may be
threaded through this metal pin, making
it impossible to remove the cover
without damaging either the security
seal or the enclosure.
Metrology labels and additional security
measures may be added to the scale as
required by the national legislation.
An alternative method of sealing the scales is to have a seal covering the joint
between the base and cover. If this seal is broken the scale must be sealed by the
relevant authorities, using either the lead wire seal or an acceptable seal between
the cover and base.
