When measuring in auto range, the value is unstable and the range
unconfirmed, therefore measurement data is not output.
Change to a fixed range and measure.
Cause:

5. The measurement
value is over range.
Cause:
Solution:
When the NULL calculation value becomes twice or more of the value
of full-scale.
Raise the source value or limiter range.
