6.1.6 Transistor hFE test

Set the measurement range dial to hFE.

Insert the adapter for transistor test into the
the measurement sockets "COM" and "
A/Ω/hFE".

Make sure the transistor is "NPN" or "PNP"
type. Insert the transistor correctly into the
corresponding transistor test socket.
Display reading is approx. transistor hFE value
(0 – 1000). Base current approx. 10 µA, V
approx.2.8 V.
7. Maintenance
Turn off the meter and remove the test
leads before you service or clean the
device.
Beyond replacing batteries and fuses, do not
attempt to repair or service your meter unless
you are qualified to do so and have the relevant
calibration, performance test, and service in-
structions.
7.1 Battery and fuse replacement
Batteries which are discharged and have not
been used for a while may leak.
Replace the battery as soon as the flat
battery icon (
Remove from the multimeter any bat-
teries which are flat or starting to disin-
tegrate.
Also remove batteries from the multi-
meter if it has not been used for a long
period of time.
Turn off the meter and remove the test
leads before opening the case.

Loosen screws with suitable screwdriver and
remove case bottom.

Replace the battery or the fuse.

7.2 Cleaning

Periodically wipe the case with a damp cloth
and mild detergent.

Do not use abrasives or solvents.
Dirt or moisture in the measurement sockets can
affect readings.

Shake out any dirt that may be in the meas-
urement sockets.

Soak a new swab with isopropyl alcohol and
CE work around the inside of each measure-
ment socket.

The packaging should be disposed of at
local recycling points.

Should you need to
dispose of the equip-
ment itself,
throw it away in nor-
mal domestic waste.
Local regulations for
the disposal of electri-
cal equipment will ap-
ply.
