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 6 for
EDP port pin assignments; see Section 6.0 on page 29
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.
