Supply voltage warning
Possible causes:

No earth connection.

Instrument is connected to an IT earthing system. Press
YES to continue normally or NO to continue in a limited
mode (measurements are disabled).
Warning:
The instrument must be earthed properly to work safely!
Resistance L-N > 30
kΩ
In pre-test a high input resistance was measured. Possible causes:

Device under test is not connected or switched on

Input fuse of device under test is blown.
Select YES to proceed with or NO to cancel measurement.
Resistance L-
N < 10 Ω
In pre-test a very low resistance of the device under test supply input
was measured. This can result in a high current after applying power
to the device under test. If the too high current is only of short
duration (caused by a short inrush current) the test can be performed
otherwise not.
Select YES to proceed with or NO to cancel measurement

Warning for improper supply voltage condition. If pressing OK
instrument will continue to work in a limited mode (measurements
are disabled).
In pre-test an external voltage between C1/P1 and C2/P2 terminals
was detected. The measurement was cancelled. Press
OK to
continue.
In pre-test a too high external voltage was detected between P and
PE terminals. The measurement was cancelled. Press
OK to
continue.
