HFE measuring:
1. Insert the accessories of the measured transistor into the mA and COM input terminals
2. Spin the function switch to the HFE range
3. Judge the polarity of the measured transistor and insert its metal pins into the corresponding
EBC jacks of the (NPN or PNP) transistor.
4. Check the amplification (HFE value) displayed on the screen. If there is no display on the
LCD, check whether the transistor pins are contacted correctly, if not, it indicates that the
measured transistor may have been damaged.
Attention!
You can’t measure the voltage signal with the input terminal if you haven’t
inserted the accessories, otherwise, the meter will be damaged!
