MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Without linearization, 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. If the output signal is out
of accuracy, when the input display value is out of accuracy,
perform the input fine adjustment. When the input display
value is correct but the output is out of accuracy, perform
the output fine adjustment. Refer to this manual, when
adjusting with front buttons. Refer to the M2ECFG users
manual (EM-5147), when adjusting with M2E Configurator
Software (model: M2ECFG). And then follow the procedure
shown below.
• INPUT FINE ADJUSTMENT
1) Set the input signal to 0 %, and adjust the input display
to 0 % by [69] Input Zero fine adjust.
2) Set the input signal to 100 %, and adjust the input dis-
play to 100 % by [70] Input Span fine adjust.
3) Again set the simulated input to 0 %, confirm the input
display.
4) If input display is shifted, repeat the procedure from 1)
to 3).
• OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0 %, and adjust the output
signal to 0 % by [71] Output Zero fine adjust.
2) Set the simulated input to 100 %, and adjust the output
signal to 100 % by [72] Output Span fine adjust.
3) Again set the simulated input to 0 %, confirm the output
signal.
4) If output signal is shifted, repeat the procedure from 1)
to 3).
