7. 5 Data - isoGraph

The isoGraph represents the chronological sequence of the insulation resistance over
time.
This graphical representation can be displayed over the following time periods: hour,
day, week, month and year.
The measured values for individual representations are stored in a separate memory.
Measured values for insulation, voltage, PGH current (current of the locating current in-
jector) and the temperature of the coupling and the locating current injector are indicat-
ed. You can switch the indication of the different measured values by pressing
100 measured values are available to represent each graph and the resolution of each
graph is determined by these values.

7. 6 History memory

Up to 1023 alarm messages and device errors are stored in the history memory with date
and time stamp. If the history memory is deleted, the minimum insulation resistance R
will also be reset at Menu/Data Measured values - Data insulation.

7. 7 Insulation fault location

When the EDS mode is activated, the ISOMETER® indicates the message "Ins. fault locat.".
Below, it indicates which EDS mode is activated. On the right side it indicates the polarity
change of the measuring pulses including the pause in between.
