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.

3.0 INSTALLATION
3.1 GENERAL INSTALLATION
•Avoid extreme temperatures. Do not place in direct sunlight or
near air conditioning vents. Avoid air movement such as from
fans or opening of doors and windows.
•Avoid unsuitable tables. Do not place near vibrating machinery.
•Avoid unstable power sources while charging the battery. Do not
use the scale near any large user of electricity such as welding
equipment or large motors.
•Avoid high humidity that might cause condensation. Avoid direct
contact with water. Do not spray or immerse the scales in water.
•Keep the weighing area clean.
•Do not stack material on the scale when not in use.
•Protect the scale from extreme temperatures, vibration and dust.

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.
