6 Command Reference
Remarks
– For analog measurements, the %_resolution parameter of the RES command
– Query command: The RES? query command returns the specified
– Related command s: ACDCI, ACDCV, ACI, ACV, APER, DCI, DCV, FREQ, FUNC,
Examples
In the following program, line 10 allows %_resolution in line 30 to control the
resolution.
10 OUTPUT 722;"NPLC 0" !SETS PLCS TO MINIMUM
20 OUTPUT 722;"DCV 6," !SELECTS DC VOLTS, 10 V RANGE
30 OUTPUT 722;"RES .001" !100 µV OF RESOLUTION ON THE 10 V RANGE
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
10 mW. However, because of line 10, the actual resolution is 100 µW.
10 OUTPUT 722;"NPLC 1000" !SETS PLCS TO MAXIMUM
20 OUTPUT 722;"OHM 1E3 !SELECTS 2-WIRE OHMS, 1 kW RANGE
30 OUTPUT 722;"RES .001 !REQUESTS 10 mW RESOLUTION
40 END

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.
