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
correct holes of the hFE Socket.
3. The meter will display the approximate hFE value at the
condition of base current 10μA and VCE2.8V.
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
Fuses rarely need replacement. They usually blow when the tester
is used incorrectly.
If “ ” appears in on the 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 back of the
case, simply remove the old fuse or battery, and replace with a
new one. Be careful to observe the correct polarity.
