4.0 KEYPAD [On / Off] Turns the scale on or off only [Print/Hold] Sends data via RS-232 and combines with Hold functions, if enabled Selects kilograms, pounds, ounces or pounds-ounces [Unit] [Tare/Zero] Sets the display to true zero or net zero by storing the current weight in the tare memory 5.0 DISPLAY 6.
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.
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.
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.
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.
The scale can be controlled by a computer using the following commands. The commands must be sent in upper case letters, i.e. “T” and not “t”. The input and output formats are as given below. Input commands format: Z H N G T Tares the scale to display the net weight- same as pressing [Tare/Zero] Sets the scale to hold if the hold function is enabled. Same as pressing the [Hold] key Sends the net weight to the RS-232 interface.
12.0 CALIBRATION • Occasionally the scale should be verified whether it is weighing correctly by measuring to a known mass. • Zero the scale. Place the mass on the centre of the platform and note the reading. Calibrate the scale, if necessary. PROCEDURE • While in the normal weighing mode, press and hold the [Tare/Zero] key for 4 seconds. • The display will show “CAL” along with the last selected unit. The unit can be changed by using the [Unit] key to calibrate in kg or lb. • Press the [Print/Hold] key.
• Place the correct calibration mass as selected by the user at the centre of the pan. • Press the [Unit]. The display will return to weighing mode. Note: If the mass loaded is more than ±20% of the factory calibration reference then an error message “CALEr” will be displayed and the scale will return to weighing without calibration being saved. Repeat the process correctly. • Remove the weight. • Verify the scale is calibrated correctly. Repeat the process, if necessary. 13.0 PARAMETER SETTING 13.
13.1.1 AUTO POWER OFF • The first parameter is to set the auto power off function. The display will show “Pr oFF” (DEFAULT SET). • Press [Tare/Zero] to toggle between “Pr on” and “Pr oFF”. Enables the Auto Power Off function. The power will be turned off after 2 minutes if a key has not been pressed for 2 minutes and the scale is at zero. If there is any weight on the scale or a key is pressed, the scale will continue to work. Disables the Auto Power Off function. The scale will not automatically turn off.
13.1.3 ENABLING OF UNITS • The third parameter is to enable or disable the weighing units so that the user can select the enabled units during the weighing operation.

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 [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.
