TRANSISTOR hFE MEASUREMENT 1. RANGE switch to the hFE position. 2. Determine whether the transistor is PNP of NPN type and locate the Emitter, Base and Collector leads. Insert the leads into the proper holes of the hFE Socket on the front panel. 3. The meter will display the approximate hFE value at the condition of base current 10 μA and Vᴄᴇ 2.8V.
