56 Counterpart Counting Scale Indicator

If you do not want to calibrate span, press Menu to exit.

6. After the Calibrate softkey is pressed, the indicator displays CALIBRATING when complete. Press TARE

(Enter)

or and the Save Exit softkey or proceed to WLIN.

To view the new AD count, navigate back to the WSPAN, and repeat Step 6; however, instead of pressing the

Calibrate softkey while viewing the value, press Save/Exit to exit.

4.2 Five-point Linearization

Five-point linearization (using the WLIN parameter) provides increased scale accuracy by calibrating the indicator

at up to five additional points between the zero and span calibrations.

Linearization is optional: if you choose not to perform linearization, skip the WLIN parameter; if linearization

values have previously been entered, these values are reset to zero during calibration. WZERO and WSPAN must

be calibrated before adding linearization points; WLIN values must be less than the WSPAN value and must not

duplicate WZERO or WSPAN.

To perform linearization, follow the procedure below:

With WLIN displayed, press Down to go to the first linearization point (POINT 1) and then press Down again to show

the weight value prompt (

WGT 1). Then press Down to show the weight value. Place test weights on the scale, and

use the numeric keypad to enter the actual test weight value. Press

enter to save the value and move to the

calibration (

CAL 1) prompt. Press down to show the current calibration value, and then press the Calibrate softkey to

calibrate the linearization point. When complete, the AD count for the linear calibration is displayed. Press

enter

again to save the calibration value and go to the next prompt (POINT 2).

Repeat for up to five linearization points. To exit the linearization parameters, press the Up key to return to WLIN.

4.3 Rezero

The optional rezero function is used to remove a calibration offset when hooks or chains are used to hang the test

weights.

The rezero function cannot be used with five-point linear calibration.

If no other apparatus was used to hang the test weights during calibration, remove the test weights and press Up to

return to the CALIBR sub-menu.

If hooks or chains were used during calibration, remove these and the test weights from the scale. With all weight

removed, go to the REZERO parameter, and press

Down to show the current zero value. Press the Calibrate softkey

to adjust the zero and span calibration values. Press

enter or Up to return to the CALIBR sub-menu.

Press Up to return to the SCALES menu, or press the Save and Exit softkey to exit setup mode.

4.4 EDP Command Calibration

To calibrate the indicator using EDP commands, the indicator EDP port must be connected to a terminal or

personal computer. See

Section 2.8.1 on page 12 for EDP port pin assignments.

Once the indicator is connected to the sending device, do the following:

1. Place the indicator in config mode (display must read SCALE — see Figure 3-8 on page 28) and remove all

weight from the scale platform. If your test weights require hooks or chains, place the hooks or chains on

the scale for zero calibration.

2. Send the SC.WZERO#n command to calibrate zero. The indicator displays CALIBRATING while calibration

is in progress.

3. Place test weights on the scale and use the SC.WVAL#n command to enter the test weight value in the

following format:

SC.WVAL=nnnnnn<CR>

4. Send the SC.WSPAN#n command to calibrate span. The indicator displays CALIBRATING while calibration

is in progress.
