Continuity test
Warning of electrical voltage
Before carrying out resistance, continuity or diode
measurements, switch off the current of the electric
circuit and discharge all capacitors.
1. Set the rotary switch to position
and use the
MODE
button to select the continuity test (
indication).
2. Insert the plug of the red measuring tip into the
V/Ω
measuring socket and the plug of the black measuring
tip into the
COM
measuring socket.
3. Connect the measuring lines to the circuit to be tested.
ð
When the circuit is closed and the resistance is smaller
than 150 Ω, an acoustic signal is emitted.
ð
When the circuit is open, OL is displayed.
Hold function
Press the
HOLD
button (2) to freeze the currently measured
value on the display. The
HOLD
indication on the display shows

Maintenance and repair
Battery change
A battery change is required when the battery status indication
displays an empty battery symbol, when incorrect measured
values are displayed or when the device can no longer be
switched on (see chapter Inserting the battery).
Info
In case of a low battery the displayed values may be
inaccurate or incorrect! If so, stop using the measuring
device and exchange the batteries immediately.
Fuse replacement
Caution
Switch the device off and remove the measuring tips
from the measuring sockets before opening the device!
Internal fuses may only ever be replaced with fuses of
the same type, never with one of a higher amperage or
with a provisional solution! Otherwise the
consequences include the risk of accidents, the
destruction of the device and the loss of warranty.
Note
Only replace fuses of the same type!
1. Fold out the stand at the rear of the device.
2. Loosen the screw of the fuse compartment and remove the
fuse compartment cover.
3. Remove the defective fuse.
