c. If the sensitivity of the selected clamp is high
(0.1A/1mV), the indicated value will be 10 times
higher than the measured value. For example, the
measured current is 10A, then the indicated value
will be 100.0A.
At the manual range mode, when only the figure 'OL'
is displayed, it indicates overrange situation and the
higher range has to be selected.
At the manual range mode, when the value scale to
be measured is unknown beforehand, set the range
selector at the highest position.
Matching problem about the meter and the sensitivity
of the clamp:
a. The sensitivity of 200A range is 200mV, that of
2000A is 2V; the sensitivity of the matching clamp is
0.1A/0.1mV. The present indicated value is same to
the measured value.
b. If the sensitivity of the selected clamp is low
(0.1A/0.01mV), the indicated value will be 10 times
lower than the measured value. For example, the
measured current is 100A, then the indicated value
will be 10.0A.
