7.0 BATTERY

• CPWplus standard can be operated from 6x AA batteries, if
desired.

• CPWplus-M and CPWplus-L scales have an internal
rechargeable battery. When the battery needs charging a

symbol on the display will turn on. The battery should be
charged when the symbol is on.

• To charge the battery, connect the power supply module to
the rear of the indicator and apply power. The scale need not
be turned on.

• The battery should be charged for 12 hours for full capacity.
The battery life is approximately 60 hours.

8.0 BACKLIGHT

The backlight for the LCD can be set by the user to always off, always
on or automatic (on only when the scale is in use or a key is pressed).
See setting of the parameter in section 13.1.2.

9.0 AUTO POWER OFF

The auto power off can be set by the user to disable the feature or to a
pre-set time interval. See setting of the parameter in section 13.1.1.

10.0 OPERATIONS

10.1 SWITCHING ON THE SCALE

• To switch on the scale, press the [On/Off] key.

• The display will show the software revision number and then

flash all the digits and symbols before counting down to zero.
This ensures all LCD segments are working. The last active
weighing unit will be displayed.

• The scale will turn off automatically to conserve battery life if

the automatic turn off parameter is set (see section 13.1.1).
To turn off the scale press the [On/Off] key.

• A battery symbol will be on when the internal battery needs
to be re-charged. Connect the power supply module to the
rear of the indicator and switch on the mains.

10.2 ZEROING

• The ZERO and TARE function is combined into one key

[Tare/Zero].

• You can press the [Tare/Zero] key at any time to set a new

zero point. Re-zeroing the scale may be necessary if a small
amount of weight is still shown when the platform is empty.

• If the scale is less than 2% of the maximum capacity,

pressing [Tare/Zero] will zero the scale. However, if the
weight on the scale is more than 2%, pressing [Tare/Zero]
will tare the scale. See the next section on taring the scale.

• The scale has an automatic zero tracking function to account
for shifting of the zero point due to the environment change
or accumulation of dust on the platform.

© Adam Equipment Company 2008

11

10.3 TARING

• Zero the scale by pressing the [Tare/ Zero] 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/Zero] key to tare the scale. The weight that
was displayed is stored as the tare value. This value is
subtracted from the display, leaving zero on the display. The
indicator “Net” will be on.

• As a product is added to the container, 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 of the product 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. The zero indicator will also be on because the
platform is back to the same condition as it was when the

[Tare/Zero] key was pressed last.

Note: If the capacity of the scale is 6000g and a container

weighing 2450g is used and tared, the scale can then be
used to weigh the material of up to 3550g.

10.4 SELECTING THE UNIT

To select the weighing unit press the [Unit] key to move form one unit to
another. The weighing unit must be enabled by the users beforehand
(see section 13.1.3). If a unit is disabled it cannot be selected by using
the [Unit] key.

10.5 WEIGHING

• When the scale is at zero, place an item to be weighed on
the platform. The display will show the weight in the unit
selected previously. The weighing result can be viewed in
other enabled units using the [Unit] key.

• If a container is used, this can be tared as described in 10.3.
The scale then shows the net weight of the material added.

13.2.1 FILTER

This parameter is for setting the speed of the display filter. For poor
environments the filter should be set at its slowest to minimise external
influences on the scale. For weighing small samples or gradual filling,
the filter should be set at a faster setting.

• Press [Tare/Zero] to scroll through the options. The display

will show “Fi 1” to “Fi 3”. If it is set to “F1 1” then the display is at
its slowest setting and at “F1 3” the display is in its fastest
setting.

• Press [Unit] to confirm the selection and move to the next

parameter.

13.2.2 ZERO TRACKING

This parameter is for setting the range of the zero tracking. Zero tracking
will aid the scale to hold or return to zero and should be increased if
large weights are left on the scale or temperature is not consistent.

• Press [Tare/Zero] to scroll through the settings. The display

will show “ZEo 1” to “ZEo 8”. If it is set to “ZEo 1” the zero tracking
is at its smallest range and “ZEo 8” the highest.

• Press [Unit] to confirm the selection and move to the next

parameter.

13.2.3 STABILIZATION RANGE

This parameter is for setting the range of the stability indicator. This is
used to determine when the scale will print automatically as well as
indicate that the weight is stable.

• Press [Tare/Zero] to scroll through the settings. The display

will show “StA 1” to “StA 8”. If it is set to “StA 8” then the stability
is at its fastest and “StA 1” the slowest.

• Press [Unit] to confirm the selection and move to the next

parameter.

13.2.4 STABILIZATION TRACKING

This parameter is for setting the size of the tracking range to indicate the
stability. This is used to stable the scale once a weighing result is
achieved.

• Press [Tare/Zero] to scroll through the settings. The display

will show “Str 1” to “Str 5”. If it is set to “Str 1” then the stability
range is at its smallest and “Str 5” the highest.

• When the desired value is displayed, press the [Print/Hold]

key to select the value and exit the Technical Parameters.
The display will count down to zero and the scale will return
to normal weighing.

• If [Unit] is pressed instead of the [Print/Hold] key, the

display will ask for Pin for entering into the Factory
Parameters. Switch off the scale.

• Switch on the scale to start the operation.

13.3 FACTORY PARAMETERS

If after the last Technical Parameter [Unit] key is pressed, the scale will
advance to the Factory Parameter section. This section contains critical
calibration reference information and is protected by a Pin Code which
can only be accessed by a qualified technician. To exit, the user must
switch off the scale when the display shows “Pi”.
