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.
