(Note) Frequency measurement and revolution measurement are always set to the Auto-Range.
Ranges of continuity test (
), diode check (
), ADP, DCA and ACA measurement are always
fixed to the default ranges. Just after the power-on operation or mode changing, the range is set to the
default range.
In the ADP measurement, three units are displayed by setting of RC1 to RC3 terminals.
The R1 to R6 of above range control table are set as a range corresponding to below table.

Changing to DC400mA range or AC400mA is available by only manual operation. Auto-range operation cannot
change to these ranges.
