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.
