and a remote indicator with a large LCD display which is easy to read from a distance.
The water-resistant keyboard has 4 easy to use function keys: GROSS/NET-UNIT-
ON/OFF-TARE.
With the standard AC adapter included and the facility for drycell batteries, the CPW
compact scales can be used in a fixed location or as a portable scale.

ASSEMBLY
The scale comes complete with the stainless steel top and a power supply module.
Plug the power supply into the socket on the side of the base. Then plug the power supply

If the wall-mount bracket is used, mount the bracket to the wall using the enclosed screws.
Then attach the display to the bracket using the 2 thumb screws put into the ends of the
housing. Tighten the screws to secure the display.
The scale can also be used with batteries for a truly portable scale.

OPERATOR’S INSTRUCTIONS
Key description
Tare
- Set the display to zero by storing the current weight in
the tare memory

- Turns the scale on or off,
Units
- Select kilograms, pounds or ounces
Gross/Net
- Select either Gross weight or Net weight when
a tare weight has been entered
To weigh on the scale turn the scale on using the
On/Off
key. After the display is at zero,
place an item to be weighed on the platform. The display will show the weight. The unit
will be shown in kilograms unless the user has selected either pounds or ounces
previously.
If an empty container is used the weight can be ignored by zeroing the display. To zero
the display, press the
TARE
key. Then when material is placed in the container only the
weight of the material will be shown.

CALIBRATION
Occasionally the scale should be verified that it is weighing correctly by measuring a
known mass of approximately the scale capacity. Tare the scale, place the mass on the
centre of the platform and note the reading. Calibrate the scale if necessary.
Before beginning make sure you have the mass specified and you know the mass is
accurate. The scale can calibrate using either kilograms or pounds. See the below for
the mass required. The following procedure assumes the parameter for local gravity
correction “Grav” has been set to OFF. If it has been set to ON then reset the value to off
as shown in the next section.
PROCEDURE
Turn the scale off.
Press and hold the
On/Off
key then press the
Units
key 3 times. Release the
On/Off
key.
The display will show a value from the internal counters. The typical value is 2000 to 8000.
Press the
Tare
key. Display will show zero.
Press the
Unit
key to select either kilograms (kg) or pounds (lb).
Place the calibration weight on the scale, centred on the platform.
CPW 25 20kg OR 50 lb
CPW 50 40kg OR 100 lb
CPW 100 100kg OR 200 lb
CPW 150 100kg OR 200 lb
The display will show a value from the internal counters again.
Press the
Tare
key again.
The display will show " CAL" then return to weighing showing the value of the weight
used.
Remove the weight. Verify the scale is calibrated correctly.
SET FUNCTIONS
The scale can be set as desired for the user. The settings that can be changed are:

calibration. Normally se t this parameter to OFF.
Advance to and then press the Gross/Net key to exit the menu.
