Regular calibration procedure is explained below:
■
CALIBRATION
Without linearization, warm up the unit for at least 10 min-
utes. Apply 0%, 25%, 50%, 75% and 100% input signals in
this order. Check that the output signals for the respective
input signals remain within accuracy described in the data
sheet.
When the output signal is out of accuracy, perform input
fine adjustment if the displayed input value is out of ac-
curacy and perform output fine adjustment if the displayed
input value is correct.
To perform the input fine adjustment or the output fine
adjustment, take the following steps with referring to
this operating manual when adjusting with front buttons
or referring to the M1ECFG users manual (EM-5981)
when adjusting with M1E Configurator Software (model:
M1ECFG).
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0 %, and adjust the displayed in-
put value to 0 % by [81]/[181]/[281]/[381] Input Zero fine
adjust.
2) Set the input signal to 100 %, and adjust the displayed
input value to 100 % by [82]/[182]/[282]/[382] Input Span
fine adjust.
3) Again set the input signal to 0 %, confirm the displayed
input value.
4) If the input signal is shifted, repeat the procedure from 1)
to 3).
• OUTPUT FINE ADJUSTMENT
1) Set the input to 0 %, and adjust the output signal to 0 %
by [91]/[191]/[291]/[391] Output Zero fine adjust.
2) Set the input signal to 100 %, and adjust the output sig-
nal to 100 % by [92]/[192]/[292]/[392] Output Span fine
adjust.
3) Again set the input signal to 0 %, confirm the output sig-
nal.
4) If the output signal is shifted, repeat the procedure from
1) to 3).
