4.7.1

Memory deletion

In the SET-UP, press the MEM key:
- The MEM symbol flashes
- ALL is shown flashing on the small display
- The main display indicates cLR
To delete the entire memory, press again on the MEM key for 2 seconds:
- The MEM symbol is displayed steady.
- ALL is shown constant on the small display
- The main display indicates FrEE
To delete the content of an OBJ: Specific TEST:
- Select the number using keys
- FrEE or OCC is shown on the main display
Press again on the MEM key for 2 seconds to delete:
- The OBJ: TEST is indicated on the small display
- The main display indicates FrEE
4.7.2 Output in bauds (RS 232)
In the SET-UP, press the PRINT key:
The main display indicates the output in bauds, i.e. 300, 600, 1200, 2400, 4800, 9600 or Parallel.
On the small display, baud appears. The value may be modified using the keys
The «Parallel» display means that the parallel mode is selected, to print on parallel printers via the
series-parallel adapter (RS 232-Centronics).

4.7.4 Voltage disturbance limit

In the SET-UP, 5 press on the
- The small display indicates dISt
- The main display shows 0.03U (flashing)
- Modify this value if necessary using the key (possible choice between: 0,10 - 0,20 - 0,03)
Note: This adjustment provides the best compromise between the measurement build-up time and the
presence of external parasite voltages (§ 3.2).
If no parasite voltage is present, this value will be chosen equal to 0.03 to obtain a rapid
measurement build-up time.
Example: If an insulation measurement is performed under a test voltage of 5000 V and the limit
equals 0.10 it will be possible to perform a correct measurement with the presence of an external
parasite voltage ≤ 500 V, to the detriment of a longer measurement build-up time.
