(2-2-2) Range setting ( Push type switch : KMS = " L ", RMS = " X " )
The range setting shown in below table is available with the " RANGE " switch.
When the switch is pressed once, the range is changed from auto to manual, and itโs range is held.
Then, the range is changed in every time by the switch operation. When the switch is pressed over
than 1 second, the range always returns to Auto-range is possible from any range statuses.

Ranges of continuity test (
), diode check (
), ADP, DCA and ACA measurements are
always fixed to their default ranges.
Just after power-on operation or changing mode, their ranges are set to the default range.
In the ADP measurement, 3 units are displayed by setting of RC1 to RC3 terminals.
The R1 to R6 of above range control table are set a range corresponding to below table.

Changing to DC400mV range or AC400mV range is available by only manual operation. Auto-range operation
cannot change to these ranges.
When the auto-range is switched in DC400mV or AC400mV range, measurement is continued in the 400mV
range. When overflow occurs in 400mV of the auto-range, its range changes to 4V range automatically.
