>1.2E-3 to 12E-3

For DSAC or DSDC:
max._input

0 to .012
>.012 to .120
>.120 to 1.2
>1.2 to 12
>12 to 120
>120 to 1E3
Power-on max._input = AUTO.
Default max._input = AUTO.
%
For most measurement functions, you specify the %_resolution as a percentage of
the max._input parameter. (Refer to the
showing how %_resolution affects frequency and period measurements;
%_resolution is ignored when the function parameter is DSAC, DSDC, SSAC, or
SSDC.)
For all functions except FREQ, PER, DSAC, DSDC, SSAC, and SSDC, the
multimeter multiplies %_resolution times max._input to determine the
measurement's resolution. For example, suppose you are measuring DC voltage,
your maximum expected input is 10 V, and you want 1 mV of resolution. To
determine %_resolution, use the equation:
