MAINTENANCE
Regular calibration procedure is explained below:
■
CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out
of tolerance, recalibrate the unit as explained in the users
manual of the M2ECFG configurator software. Or follow
the procedure shown below.
•
INPUT FINE ADJUSTMENT
Set the input signal to 0 %, and adjust the input to 0 % by
[06] Angle offset.
•
OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0 %, and adjust the output to
0 % by [71] Output Zero fine adjust.
2) Set the simulated input to 100 %, and adjust the output
to 100 % by [72] Output Span fine adjust.
3) Again set the simulated input to 0 %, confirm the output.
4) If output is shifted, repeat the procedure from 1) to 3).
