Figure 3-9. Current Measurement 200 mA to 10 A
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.
Diode / Continuity Testing
Press G to toggle between the continuity and diode test functions for the primary
display. (These functions cannot be selected for the secondary display.)
To perform a continuity test:
1. If required, press G to select the continuity test function.
