Continuity Test
1. Turn the rotary switch to the measurement function “ ” and
select the continuity test function with the "FUNC." button. The
display will show “
”, “OL” and the “
W
” symbol.
2. Insert the red probe in the “ ” socket and insert the black
probe in the “COM” socket.
3. Connect the probes’ tips to the measuring object.
4. The buzzer will signal if continuity is present (resistance is less
than 30 ±5
W
.) and the LED-indicator of the device will turn
green. In addition the resistance will be shown on the screen.
The LED-indicator will turn red, if the resistance is between
30
W
and 50
W
. If the screen shows “OL”, the measurement
range has been exceeded or the measuring circuit is defective.
WARNING:
When testing for continuity on the line, disconnect the power
supply, ensure there is no source of voltage, and discharge
all capacitors. Otherwise, the instrument might get damaged
and might be in danger of an electric shock. When measuring
is finished, always remove the probes from the measuring
object and the device.
