SAFETYOPERATIONMAINTENANCE SETUP
Transistor (hFE) Measurement
Test transistors to ensure proper function.
1. Turn the Range Selector Switch to the
hFE position. Turn Multimeter ON.
2. Insert transistor pins into the
appropriate holes of the hFE
testing socket (NPN or PNP)
according to the EBC (Emitter,
Base, Collector) sequence.
3. The meter will show the
approximate hFE value.
4. When testing is complete, turn
Multimeter OFF, remove and store
Transistor and Multimeter.
Diode Measurement
Test the voltage drop in diodes.
WARNING! To prevent electric shock, turn
off all power and fully discharge capacitors
in the circuit under test before measuring.
1. Turn the Range Selector Switch
to the Diode ( ) position.
2. Plug the black lead into the COM
Jack. Plug the red lead into the
VΩmA Jack. Turn Multimeter ON.
3. Connect red probe to the anode of the
diode and the black to the cathode.
4. The approximate forward voltage
drop of the diode will be displayed
in mV. If the connection is
reversed, only “1” will be shown.
5. When testing is complete, turn
Multimeter OFF, remove Test
Leads and store with Multimeter.
