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 2.3.2 on page 8 for
EDP port pin assignments; see Section 10.0 on
page 46 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
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
calibration is in progress.
4.3 Revolution Calibration
™
To calibrate the indicator using Revolution, the
indicator EDP port must be connected to a PC running
the Revolution configuration utility.
Use the following procedure to calibrate the indicator:
1. Place the indicator in setup mode (display
reads ) and remove all weight from
CONFIG
the scale platform.
2. Select
Calibrate Indicator
main menu.
3. On the Indicator Calibration display, select

commands to set and calibrate a single
linearization point:
WLIN.V1=nnnnn<CR>
WLIN.C1<CR>
The WLIN.V1 command sets the test weight
value (nnnnn) for linearization point 1. The
WLIN.C1 command calibrates the point.
Repeat using the WLIN.Vx and WLIN.Cx
commands as required
linearization points.
6. 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
while the zero and span calibrations are
adjusted.
7. Send the KUPARROW or KEXIT EDP
command to exit setup mode.
4. Revolution uploads calibration data from the
indicator then presents the information in a
display.

Yes No
7. The Zero Calibration dialog box prompts you
to remove all weight from the scale. Clear the
scale and click to begin zero calibration. If

your test weights require hooks or chains,
place the hooks or chains on the scale for zero
