Insert a shock-proof plug (IP 2x with shrouded contacts) in the socket of
the
EP4
continuity tester when performing measurements on measuring
points that may be energised.
When the device is switched on and connected to a voltage of more than 15 V,
an acoustic and visual alarm is provided (see 4.4). In this case, the test object
must be de-energised before performing resistance measurements.
3. Initial operation
A 9 V battery (IEC 6 LR 61) is already included in the scope of delivery of the
EP4
continuity tester. The device is thus operational. Observe section 5 of these
instructions for use prior to initial operation of the device or after extended
periods of storage.
Switching the device on:
⇒
Shortly press the button (
+1
is displayed and the middle LED lights
up).
+1
indicates that the device is operational.
Switch the device off:
⇒
Press the button again. The device switches off automatically after
about 20 seconds if no button is pressed.
Self-test:
⇒
Keep the button pressed when switching on the device; the device is
in good order and condition if all LCD segments are displayed, the three
LEDs light up, an acoustic signal sounds and the middle LED lights up
when releasing the
+1
button.
If the display fails during a self-test (completely or partly) or the device
does not indicate readiness for operation, the
EP4
continuity tester must
be refrained from use and send in for repair.
⇒
If the
“Fuse ERR”
fault message is displayed, the device is no longer
operational and the fuse must be replaced by the manufacturer.
