The settings are also applied to those in Sections 7.3 “ FFT Analyzer ” and 7.4 “ In-
rush Current Measurement .” Note, however, that Auto Range is not applied.
The peak current that can be measured is four times the range value in the 0.5 to 10 A
range and 2.5 times in the 20 A range.
•
If waveforms with a large crest factor are input while Auto Range is ON, the
range may not remain constant. In this case, set Auto Range to OFF.
•
The maximum value of input current is 50 Apeak. Exceeding this value
may burn the current detector.
•
If the current detector overheats, the OHP icon appears on the upper part
of the display. Immediately shut down the power to the EUT to cut the
input current of this product. Restart the test after the OHP icon
disappears.
