MEASUREMENT OPERATION
21
1. Turn the rotary switch to the “hFE” position.
2. Put the multi-purpose socket into the terminal.
3. Check whether the transistor is either PNP or NPN or SMT, then connect the
transistor to be measured to the corresponding jacks.
4. The LCD display shows the hFE reference value. The testing requirement: basic
current 10µA,Vce of 2.3V.
Warning:
 To avoid damage to the Meter or to the DUT, do not input any voltage over
60V DC or 30V AC.
 Take off the multi-purpose socket after the measurement.
