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.
2. Connect the test leads between the Meter and the circuit under test as shown in
Figure 3-10.
The beeper emits a continuous tone if the input is below 20 Ω.
To perform a diode or transistor junction test:
1. If required, press G to select the diode test function.
2. Connect the test leads between the Meter and the diode or transistor junction as
shown in Figure 3-11.
The forward voltage of the semiconductor junction (or junctions) is measured.
Readings are displayed in the 2 V range at the fast measurement rate. The Meter
displays 0L if the input is above +2 V.
