4.2 EDP Command Calibration
To calibrate the indicator using EDP commands, the indicator COM 1 port must be connected to a terminal or
personal computer. See Section 6.0 on page 42 for more information about using EDP commands.
Once the indicator is connected to the sending device, use the following steps:
1. Place the indicator in configuration mode (display reads CONFIG ) and remove all weight from the scale
platform. If your test weights require hooks or chains, place them on the scale for zero calibration.
2. Send the SC.WZERO EDP command to calibrate zero. The indicator displays *CAL* while calibration is in
progress.
3. Place test weights on the scale and use the SC.WVAL command to enter the test weight value in the
following format:
WVAL=nnnnnn
4. Send the SC.WSPAN EDP command to calibrate span. The indicator displays *CAL* while calibration is in
progress.
5. To remove an offset value, clear all weight from the scale, including items used to hang test weights, and then
send the SC.REZERO EDP command. The indicator displays *CAL* while the zero and span calibrations are
adjusted.
6. Send the KUPARROW EDP command to exit configuration mode.
4.3 Revolution Calibration
To calibrate the indicator using Revolution, the indicator COM 1 port must be connected to a PC running the
Revolution configuration utility.
Use the following procedure to calibrate the indicator:
1. Select Calibration Wizard from the Revolution tools menu.
2. Revolution uploads calibration data from the indicator and presents the information in the calibration wizard,
as shown in Figure 4-1.

3. Enter the Value of Test Weight to be used for span calibration and click OK .
4. The Zero Calibration dialog box prompts you to remove all weight from the scale. Clear the scale and click
OK to begin zero calibration.
If your test weights require hooks or chains, place them on the scale for zero calibration.
5. When zero calibration is complete, the Span Calibration dialog box prompts you to place test weights on the
scale for span calibration. Place test weights on the scale and click OK .
6. When calibration is complete, the New Settings fields of the Indicator Calibration display are filled in. Click
Exit to save the new values and return to the Revolution main menu; to restore the previous calibration values,
click Restore Settings .
