Quick user guide METRAOHM 413
This is a brief instruction. Observe
the entire operating instruction
of the METRAOHM 413 and
follow all instruction contained
therein.
Standard measurment up to 2 M
Tests with 200 mA according to EN/IEC 61557-4
only at resistance < 10 Ω, polarity change has to be
performed manual
.
Attention!
First switch on the METRAOHM 413 and
afterwards contact the measuring point
with the test electrode. Button
may not
be pressed thereby, otherwise the
METRAOHM 413 may be damaged by
external voltages.
1. Measurement setup:
Connect the insulated 4 mm-connector of the
the measuring line to the socket of the
METRAOHM 413.
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 o for zero
balancing.
Contact the test electrode of the METRAOHM 413
with the reference earth and ensure safe contact.
Press button
and then button
at the
same time. Zero balancing will be performed.
3. Standard measurment:
Press button
shortly to start the
measurement.
4. Change of polarity:
Press button
+/-
, the polarity is indicated by the
green LEDs as well as the “+ Rdy“ or “- Rdy
indication.
