4. Connect the red test lead to the anode of the diode to
be tested, and the black test lead to the cathode.
5. The display will show the approximate forward voltage
of the diode. If the connection is reversed,
"
OL
"
will be
shown on the display.
Transistor hFE
1. Set the range switch to
"
hFE
"
position.
2. Refer to the Figure 2, connect the adapter to the
"
COM
"
jack and the
"
V Hz
"
jack.
3. Identify whether the transistor is NPN or PNP type and
locate emitter, base and collector lead. Insert leads of
the transistor to be tested into proper holes of the
transistor test socket of the adapter.
4. LCD display will show the approximate hFE value.
Note:
This measurement can be used to determine whether the
transistor is good, and be used to compare the hFE of one
transistor with the hFE of another transistor, the reading on
the display is only for reference.
If you want to measure a transistor accurately, please use
a professional measurement tool.
