11.2.4 Range
Range (MOhm)
- select the measurement range in which the insulation
resistance is to be evaluated. The range is dependent on the expected
resistance.
1 MOhm
measurement range
10 MOhm
measurement range
100 MOhm
measurement range
Rmin (MOhm)
: - lowest insulation resistance allowed. If the resistance
is less than this value, an insulation fault R<Rmin is indicated. The
Rmin is dependent on the measurement range and can be between
1 and 100 MOhm.
Contact monitoring „on/off
“ - switches on the evaluation for the insula-
tion resistance. During the testing the resistance must not drop below
a pre-defined insulation resistance. This ensures contact is made to
the test object.
off
- no evaluation of the Rmax
on
- evaluation of the Rmax active.
Rmax (MOhm)
: - largest insulation resistance allowed. If this value
is exceeded, a fault (kein Kontakt (no contact)) is indicated. This
