3. Does not output or
display the measure-
ment values.
Cause:

The output status is Standby or Suspend.
Set the output status to Operate and check that the
OPR
indicator on the
front panel is ON.
Cause:
Solution:
Measurement is OFF.
Verify measurement ON/OFF setting.
Cause:
Solution:
When measuring in the auto range, the value is unstable and the range
unconfirmed, therefore measurement data is not output.
Change to the fixed range and measure.
Cause:
Solution:
A trigger signal is not input although the trigger signal cable is con-
nected to the external trigger.
Verify the TRIG INPUT connection cable and the signal.

Incorrect cable connection.
Check cable connections again.
Cause:
Solution:
Disconnected cable.
Verify the cables with a tester. If in error, replace it.
Cause:
Solution:
Some cable is connected to a wrong terminal.
Check cable connections again.
Cause:
Solution:
The induction noise scatters the measured values.
Set the integration time to 1 PLC or longer.
5. The measurement
value is over range.
Cause:
Solution:
The measured value after NULL calculation becomes twice or more of
the full-scale value.
Raise the source value or limiter range.
