Error Messages, Troubleshooting
11.1
Display is Off
Note: The L or N conductor connection is
probably faulty.
If the mains are OK, the internal fuse may
have blown.
11.2
Touch Current Measurement
Indicates 0.000 mA
This is not an error – there simply isn’t any
touch current.
11.3
Touch Current Measurement Greater
than 0.5 mA
Attention!
!
Voltage to accessible conductive
parts!
➭
Immediately disconnect the DUT from
the mains outlet!
Conduct an insulation resistance measure-
ment between accessible conductive parts
and the DUT’s mains connection. In order to
ensure that all insulation is tested, all switch-
ing elements must be closed during the
insulation measurement.
The measured value must be greater than
2 M
. After insulation measurement has
been successfully completed, measure
touch current. The measured value must be
less than 0.5 mA.
11.4
“F” Displayed for Differential Current
Measurement
If the test instrument’s power ratings and
those on the DUT’s serial plate are identical,
the DUT’s insulation performance is inade-
quate!
➭
Disconnect the DUT from the mains out-
let.
➭
Use an insulation measuring instrument
to locate the fault.
Line voltages are displayed incorrectly.
➭
Check line voltage with a measuring in-
strument.
If the test instrument is faulty, it must be sent
to the service department or replaced.
11.5
Bluetooth Communication
Bluetooth is always on.
Pairing is required during initial startup with a
PC.
The measuring instrument is not found.
The
METRALINE PAT
is still connected to
another device.
➭
Terminate the connection and try to con-
nect again – restart the measuring instru-
ment if necessary.
Bluetooth connection is interrupted or intermit-
tent.
➭
Make sure that the mobile device is not
in the economy mode.
Distance between the measuring instrument
and the mobile device may not exceed 10
meters.
➭
Make sure that no devices are close by
which emit electromagnetic interference
(e.g. switched-mode power supplies that
don’t comply with EMC standards, fre-
quency converters or switchgear).
Measured value transmission doesn’t work.
➭
Check the hardware keyboard settings
at the mobile device.
