8.6 TRANSISTOR TESTING
1. Set the measurement function range switch to the ‘hFE’ position.
2. Determine whether the transistor under testing is NPN or PNP. Insert the leads into the
correct holes of hFE socket on the front panel.
8.7 DIODE TEST
1. Connect the black test lead to COM probe socket and the red to VΩmA probe socket.
2.
Set the measurement function range switch to F position.
Note:
A) The meter will show approximate forward voltage drop of the diode.
8.8 CONTINUITY TESTING
1. Connect the black test lead to COM probe socket and the red to VΩmA probe socket.
2.
Set the measurement function range switch to the position.
Note:
If the circuit is open, figure ‘1’ will be displayed.
