personal computer. See Section 5.0 on page 44 for more information about using EDP commands.

CONFIG
).
2. Remove all weight from the scale platform.
3. If your test weights require hooks or chains, place the hooks or chains on the scale for zero calibration.
4. Send the WZERO EDP command to calibrate zero. The indicator displays
*CAL*
while calibration is in
progress.

*CAL*
while calibration is in
progress.
8. To remove an offset value, clear all weight from the scale, including hooks or chains used to hang test

*CAL*
while the zero and span
calibrations are adjusted.
