Automatic Input Terminal Detection
For ac and dc current measurement functions, the Meter automatically detects the signal
input between the
mA
and
10 A
input terminals. A front-panel annunciator indicates
whether the Meter is in the mA or A ranges.
If a test lead is inserted in to the
mA
input terminal and there isn’t a test lead in the
10 A
terminal, then only the 200 μA to 200 mA ranges are selectable. If the
10 A
terminal has
a test lead, then only the 2 A and 10 A ranges are selectable.
