Displays

Digital Display With additional bar graphs or pointer

depending on selection with a.disp

parameter, backlit (transflective);

leading zeros can be suppressed at the

digital display depending on selection with

0.disp parameter;

overranging indicated with 0L at display;

dimensions: 65 x 36 mm

Cable resistance

If measurement results for the two direc-

tions of current flow (polarity reversal) differ

by more than 10% (this corresponds to

typical measuring error for the instru-

ments), both measured values are dis-

played next to each other with reduced

resolution.

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
