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
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.
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.
