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
CE
AUDIBLE CONTINUITY TEST
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.
