To measure a transistor:
1.
Set the rotary switch to the "hFE" position.
2.
Connect the black test lead to the "COM" socket and the red test lead to
the "VΩmAhFE" socket.
3.
Connect the test probes to the transistor adapter socket with correct
polarity: the "COM" probe (black) goes into the "COM" socket of the
adapter; the red probe goes into the other socket. Push the probes into
the adapter as far as they go.
4.
Determine whether the transistor is of the NPN or PNP type and locate
the emitter, the base and the collector. Insert the leads into the proper
holes in the included adaptor socket.
The display shows the approximate hFE-value (current gain).
7.10 Cable Test
Never use the tester on live wires; this will damage the tester.
Use the DMM with the remote cable unit tester for testing network or
telephone cables (RJ45 (8P8C), RJ12 (6P6C), RJ11 (6P4C)) and USB cables.
1.
Slide the terminal cover into the upper position (see illustration on
page 2).
2.
Set the rotary switch to the "AUTO" position.
3.
Plug in the cable to be tested as follows:
o USB cable: plug one end into the USB jack [8] on the DMM; plug the
other end into the USB jack [11] of the remote unit.
o Twisted pair: plug one end into the jack [9] on the DMM; plug the
other end into the jack [12] of the remote unit.
The cable test lights on the DMM [10] and on the remote unit [13] light up
in sequence.
You can interpret the cable test lights as follows:
Description
Good connection: all indicators
light up in sequence.
Notes: Indicator G lights up only
for cables with a ground (GND). For
RJ11 cables, the lights on the
remote light up in reverse
sequence.
Open circuit: wire 2 is broken;
indicator 2 does not light up on
DMM and remote.
