have made too many errors during configuration and you decided to re-configure the instrument, it is possible to restore
the factory configuration. This action allows to put the instrument in a defined condition (the same it was at the first power

shows 0;
2. Using and buttons set the value -481;
3. Push button;
4. The instrument will turn OFF all LEDs for a few seconds, then the upper display will show dFLt (default) and
then all LEDs are turned ON for 2 seconds. At this point the instrument restarts as for a new power ON.
The procedure is complete.
