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

min

 will also 

be reset in the Data-isoGraph at 

Menu -> Data Measured values -> Reset Data-isoGraph

.

7.7   Insulation fault location

When EDS mode is activated, the ISOMETER® indicates the message "Ins. fault locat.". Below, 
on the left side it indicates which EDS mode is activated. On the right side, it indicates the po-
larity change of the measuring pulses including the pause in between. The different pulse 
phases are indicated by the corresponding symbols. *

Positive measuring pulse *

Pause

Negative measuring pulse *

The insulation fault location has been started manually and runs conti-
nuously. No insulation measurement takes place.

43 s

Insulation fault location in auto mode and 1 cycle. 
Time countdown of a measurement cycle.  

- - -

Time cannot be displayed

* Display for low-frequency measurements

In the LAB procedure, the pulse can last up to one minute. Therefore, there is
no constant "changing" of the display symbols. The respective symbols are
displayed continuously for the pulse time of up to 1 minute.
