transformer jaw, The Meter can only measure one conductor at a time.
When the measuring current >1A, press Hz button to step through AC current,
frequency and duty cycle measurement mode. But the frequency or duty cycle
readings obtained from this range is only for reference.
Press SELECT to carry out surge current measurement.
Set the rotary switch to 1000A
Press SELECT when the Meter displays the minimum readings. The Meter then
displays “-----’’ indicating it is ready to carry out surge current measurement.
Turn on the electrical equipments at that time to measure the moment start up
current.
Turn on the electrical equipment at this time to measure the momentary start up
current.
When the Meter is at surge current measurement, it is locked to the highest
measurement range.
