TRANSISTOR hFE MEASUREMENT

1. Set 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.

3. The meter will display the approximate hFE

value at the condition of base current 10μA

and V

1. Red lead to "VΩmA", Black lead to "COM".

2. RANGE switch to " " position.

3. Connect test leads to two points of circuit to

be tested. If the resistance is lower then 30Ω

±20Ω, the buzzer will sound.

BATTERY AND FUSE REPLACEMENT

Fuse rarely need replacement and blow almost

always as a result of operator error.

If "

" appears in display, it indicates that the

battery should be replaced.

To replace battery & Fuse (F500mA/250V for mA

terminal and F5A/250V for 5A terminal) remove

the 2 screws in the bottom of the case, simply

remove the old, and replace with a new one. Be

careful to observe polarity.

2.8V.
