2.2.1 Digital display.
The main digital display indicates the values for insulation measurement: resistance, DAR PI, DD or
capacity).
The small digital display indicates the voltage measured or applied by the instrument.
During the insulation measurement, the elapsed time or
After the recording of a group of data (C.A 6547), the small display also indicates the date and time in
MR (Memory recall) mode. It is also used to indicate the memory address using the OBJ number. TEST
(see § 2.2.3 Symbols).
2.2.2 Bargraph
The bargraph is active during insulation measurement (0.1 MΩ to 1 TΩ). It is also used, to indicate the
battery charge, and the memory space, a segment representing approximately 50 groups of storable
values.
2.2.3 Symbols
MEM/MR indicates the memorisation (MEM) or memory reading (MR) operations (C.A 6547)
OBJ: TEST Memory address (C.A 6547): the number is displayed above, on the small digital display.
COM Flashes on the screen when the data is transmitted to the serial interface (C.A 6547) or is
