Automatic measurement up to
10
Ω
Tests with 200 mA and automatic polarity change
according to EN/IEC 61557-4
.
Attention!
First switch on the EP 4 and afterwards
contact the measuring point with the test
electrode. Button may
not
be pressed
thereby, otherwise the EP can be damaged
by external voltages.
1. Measurement setup:
Connect the insulated 4 mm-connector of the
the
measuring line to the socket of the EP.
Contact the reference earth with the test
electrode of the measuring line (e.g. by clamp).
2. Zero balancing:
The tester has to be switched off for zero
balancing.
Contact the test electrode of the EP 4 to
the reference earth and ensure
safe contact
.
Press button
and then the button
at the
same time. The zero balance will be performed.
3. Select automatic measurement:
Hold button
+/-
pressed until POL +/- LEDs light
up quickly and “AuTo“ appears on the display.
4. Automatic measurement:
Short press button to start automatic
measurement. The pole changing is carried out
automatically.
5. Querying of stored measured / - :
Press button
+/-
to switch between the
measured resistance value with + polarity and
– polarity.
External voltage warning
Acoustic warning and red LED for interference vol-
tage from 15 V to 400 V (voltage is displayed in V)
Continuity signal
An acoustic signal sounds for 2 seconds during
measurement for resistance values < 2 Ω.
