WARNING: Disconnect the test leads from any source of voltage
before removing the back cover or the battery/fuse door. Do not operate
your meter until the rear housing is in place and fastened
securely.

4.8. Iceo (LEAKAGE CURRENT) TEST
1. Insert the test leads into COM (Black lead) and "+" socket (Red lead).
2. Set the function switch to X10 (15mA) for small size transistor, or to X1
(150mA) for big size transistor.
3. Short the test leads and turn on adjusting knob to set the pointer to
the zero position.
4. Making Measurement:
A. For NPN transistor, the "N" terminal of the tester is connected to the
COLLECTOR (C) of the transistor, the "P" terminal is connected to the
EMITTER (E) of the transistor.
B. For PNP transistor, reverse the connection of NPN transistor connect.
5. For the lceo range, if the pointer is not within the LEAK zone or the
pointer moves up near to the full scale, it means that the transistor is
not good. Otherwise, it is a good transistor.
4.9. hFE (DC AMPLIFICATION) TEST
1. Insert the test leads into COM (Black lead) and "+" socket (Red lead).
2. Set the function switch to X10.
3. Short the test leads and turn on 0
Ω adjusting knob to set the pointer to
zero position.
4. Making Measurement:
A. For NPN FE transistor.
ii. Plug the hFE connector into "N" terminal and connect its red clip
to the collector and the black one to the base of the transistor.
B. For the PNP transistor,
i. Connect the "N" terminal of the tester to the emitter of the
transistor.
ii. Plug the hFE connector into the "P" terminal and connect the clips
in the same way as NPN transistor connection.
5. Read the hFE scale. The value of the reading is lc/lb, which is the DC
amplication degree of the transistor.
5. BATTERY REPLACEMENT
1. Take out the plastic protection cover first
2. Remove Philips head screw and lift off the rear housing of the meter.
3. Replace old battery with fresh 9V and AA type battery.
4. Replace the rear cover and secure the screw.
