Err1
All measurements
with protective
conductor
Potential difference U

PE (earthing contact)
(frequency f 50 Hz)
Remedy: inspect PE connection
Note: only if appears: Measurement can nevertheless be started by pressing
the ON/START key again.

1) Voltage too high (U > 253 V) for RCD test with direct current
2) U always U > 550 V with 500 mA
3) U > 440 V for I

with 500 mA
Err3 I
N
RCD is tripped too early or is defective.
Remedy: test circuit for bias current.
Err4 Z
L-PE
RCD is tripped too early or is defective.
Remedy: test with “DC + positive half-wave”.
Err5 I
N
/ I
F
RCD tripped during touch voltage measurement.
Remedy: check selected nominal test current.
Err6 EXTRA PRCD
The PRCD has been tripped.
Reason: poor contact or defective PRCD.
Err7 All except for U
Externally accessible fuse is blown.
The voltage ranges remain functional even if fuses have blown.
Special case, R
LO
: Interference voltage during measurement may result in a blown
fuse.
Remedy: replace fuse
Observe notes regarding fuse replacement in section 18.3!

Frequency out of permissible range.
Remedy: Inspect mains connection.
Err9 All
Excessive temperature inside the test instrument.
Remedy: wait for test instrument to cool down.
Err9
RINS
/ RLO
Interference voltage
Remedy: device under test must be disconnected from all sources of voltage.
Err11
