6.6.1 Menu 1: Alarm/meas. values
EDS... displays the following for each measuring channel: Alarm status,
test current I(ds), residual current I(d).
Column 1: Channel number 1…12
Column 2: Alarm status:
No alarm
Alarm
Column 3: I(ds): Currently measured test current.
Column 4: I(d): Currently measured residual current.
The accuracy of the displayed test current depends on the
system leakage capacitances.
The IRDH575 / PGH... test current is limited. Consequently,
the insulation fault resistance may in fact be lower than
the displayed test current suggests.
