test start, based upon the fact that the minimum measurement
current is not sensed.
The High IDC current module has a thermal protection: at the
intervention, the measurement current is taken to zero, and the
test interrupted.
Remember that if you test with a current more than 100 A the
test will have a limited duration, as per the following table.
CURRENT

100 600 STEADY - 2.8
200 1000 4 min 15 5.6
400 1600 15 5 11.3
Keep the test duration as short as possible: if you exceed the
above table, the test set stops automatically the test, and you
have to wait until the recover time is elapsed. Also, consider that
you are sinking power from the mains supply: the supply cable
wires should have a cross section suitable for a current supply of
10 to 20 A. The table lists the current supply.
When you are satisfied with the result, press SAVE: test result is
saved. Return to zero the adjustment knob (6).
WHEN YOU DISCONNECT THE PRIMARY CABLES, PLEASE
CONSIDER THE TEST DURATION. IF IT WAS LONG,
CONNECTION VICE AND CABLE CAN BE VERY HOT: USE
PROTECTION GLOVES!
If, during the test, you suddenly see that you cannot generate
the current, this means that you have over-heated the module,
and the thermal protection is intervened, cutting the measurement
output. All you have to do is to wait until the module is cooled
down, and the measurement comes back.
