226 Chapter 6 Command Reference
For frequency or period measurements, the defau1t %_resolution is .00001
which selects a gate time of 1s and 7 digits of resolution.
For sampled ACV or ACDCV, the default %_resolution is 0.01% for
SETACV SYNC or 0.4% for SETACV RNDM.
For all other measurement functions, the default resolution is determined by
the present integration time.
•
For analog measurements, the %_resolution parameter of the RES command
operates slightly differently than the %_resolution parameter of a function
command (FUNC, ACV, DCV, etc.) or the RANGE command. When used with
the RES command, %_resolution is multiplied times the range to determine the
actual resolution. When used with a function command or the RANGE
command, %_resolution is multiplied times that command's max._input
parameter. The max._input parameter may or may not be the value of a
measurement range.
•
Query Command. The RES? query command returns the specified
%_resolution. Refer to "Query Commands" near the front of this chapter for
more information.

In the following program, line 10 allows %_resolution in line 30 to control the
resolution.
10 OUTPUT 722;"NPLC 0"
20 OUTPUT 722;"DCV 6,"
30 OUTPUT 722;"RES .001"
40 END
In the following program, line 10 sets the number of PLCs to 1000. This
corresponds to maximum resolution (7.5 digits) and prevents the RES command
in line 30 from affecting the measurement. The requested resolution in line 30 is
10m W . However, because of line 10, the actual resolution is 100µ
10 OUTPUT 722;"NPLC 1000"
20 OUTPUT 722;"OHM 1E3
30 OUTPUT 722;"RES .001
40 END
Allows you to set the multimeter to the power-on state without cycling power.

!SELECTS DC VOLTS, 10V RANGE
!100µV OF RESOLUTION ON THE 10V RANGE
!SETS PLCS TO MAXIMUM
