Displays
Digital display With additional bar graph or pointer
depending on selection with a.disp
parameter, backlit (transflective);
leading zeros can be suppressed at the
digital display depending on 0.disp
parameter;
overranging indicated with 0L at display;

Limit LED LED lights up red to indicate an exceeded
limit value
LED lights up green to indicate adherence
to the limit value
LED LED lights up red to indicate:
– the presence of an external voltage
bevore insulation testing
(U > 50 V)
with the device switched on or off
(device switched off not with M550N)
– the presence of the test/measuring voltage
during (insulation) measurement (U > 50 V)
the presence of a residual voltage
after insulation testing (U > 50 V)
with the device switched on or off
at LCD Detection of external voltage at the LCD
with the device switched on where U DC >
50 V and U AC > 40 V (50 Hz) for all mea-
suring functions
