Transistor Test
1. Set the rotary switch to the ‘’hFE’’ position.
2. Determine whether the transistor under testing is NPN or PNP and locate the
emitter, base and collector leads. Insert then leads into the proper holes of the
hFE socket on the front of the panel.
3. Read the approximate hFE value at the test condition of base current 10µA and
Vce 3V.
*Attention*
To avoid electrical shock, remove the test leads from measurement circuits
before testing a transistor.
Audible Continuity Test
1. Connect the red test lead to the VΩmA jack and the black test lead to the COM
jack.
2. Set the range switch to the ‘’ ’’ position.
3. Connect the test leads to two points of the circuit to be tested. If continuity
exists, the built-in buzzer will sound.
Battery & Fuse Replacement
If the battery symbol ‘ ’ appears on the display, it indicates that the battery
should be replaced.
The fuse rarely needs replacement. A blown fuse is almost always operator error.
To replace battery and fuse, remove the two screws on the back of the case.
Simply remove the old one and replace with a new one.
Be careful to observe battery polarity.
*Warning*
Before attempting to open the case, always be sure that the test leads have
been disconnected from measurement circuits. Close the case and tighten
screws completely before using the meter to avoid electric shock.
