CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
the full-scale.
5) Output: Check that the load resistance meets the de-
scribed specifications.
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 input fine adjustment.
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-5133-B), 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 display
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 sig-
nal 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).
