FUNCTIONAL DESCRIPTION

4.1.

RANGE / AC+DC key

The RANGE key is operative in following positions of the selector switch :
This key makes it possible :
• In AUTO (Autoraging) mode to switch to MANUAL mode (short press).
• In MANUAL mode, to select the next range (short press) or return to AUTO mode
