4.2 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 2.3.3 on page 5 for
EDP port pin assignments; see Section 5.0 on page 24
for more information about using EDP commands.
Once the indicator is connected to the sending device,
do the following:
1. Place the indicator in setup mode (display
reads CONFIG ) 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 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
WVAL command to enter the test weight
value in the following format:
WVAL=nnnnnn<CR>
4. Send the 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 hooks or chains used
to hang test weights, then send the REZERO
EDP command. The indicator displays
*CAL*
while the zero and span calibrations are
adjusted.
6. Send the KUPARROW EDP command to exit
setup mode.
4.3 Revolution ™ Calibration
To calibrate the indicator using Revolution, the
indicator EDP port must be connected to a PC running

display like that shown in Figure 4-3.
Figure 4-3. Revolution Calibration Display
4. Enter the Value of Test Weight to be used for
span calibration then click OK .
5. The Zero Calibration dialog box prompts you
to remove all weight from the scale. Clear the
scale and click
OK to begin zero calibration.
NOTE: If your test weights require hooks or
chains, place the hooks or chains on the scale
for zero calibration.
6. When zero calibration is complete, the Span
Calibration dialog box prompts you to place
test weights on the scale for span calibration.
Place tests weights on the scale then click
OK .
7. When span calibration is complete, the
Rezero dialog box prompts you to remove
weights from the scale. Remove the weights
then click
OK .
8. 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 .
