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 sig-
nal remains within accuracy described in the data sheet. If
the output signal is out of accuracy, when the input display
value is out of accuracy, perform the teach, when the input
display value is correct but the output is out of accuracy,
perform the output fine adjustment. Refer to the operating
manual (EM-5983-B), when adjusting with front buttons.
Refer to the M1ECFG users manual (EM-5981), when ad-
justing with M1E Configurator Software (model: M1ECFG).
And then follow the procedure shown below.
• OUTPUT FINE ADJUSTMENT
1) Set the simulated input to 0 %, and adjust the output
signal to 0 % by [82]/[182] Output Zero fine adjust.
2) Set the simulated input to 100 %, and adjust the output
signal to 100 % by [83]/[183] 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).
