RES
Resolution. Specifies reading resolution.
Syntax
RES [%_resolution]
%
For frequency and period measurements, the %_resolution parameter specifies
the digits of resolution and the gate time as shown below. (%_resolution also
affects the reading rate. Refer to the
more information.) If you default the %_resolution parameter for frequency or
period measurements, the multimeter uses .00001.

voltage range is ±12 VDC (autorange only). To specify ratio measurements,
you first select the measurement function (and the measurement method for
ACV or ACDCV) and then enable ratio measurements with the RATIO
command (see example below).
