Default at DC. Press SELECT button momentarily to select AC.
*Note: When measuring a 3-phase system, special attention should be taken to the
phase-to-phase voltage which is significantly higher than the phase-to-earth voltage.
To avoid exceeding the voltage rating of the protection fuse(s) accidentally, always
consider the phase-to-phase voltage as the working voltage for the protection fuse(s).
