Comparator - Fluke BT5300 Series User Manual

If the 300 mA measurement current is used, the Instrument will be more sensitive
to the eddy current of the measuring loop circuit. If the test can't be completed
with a large measurement current, you can reduce the effects of eddy current on
test cables, or the system refer to
Suggested Solution, or reduce the measurement current, to complete the test.
