Examples
In the following program, line 10 allows %_resolution in line 20 to control the
resolution. The resolution specified by line 20 is 6 V × .0000167 = 100 µV.
10 OUTPUT 722;"NPLC 0" !SETS PLCS TO MINIMUM
20 OUTPUT 722;"FUNC DCV,6,.00167" !SELECTS DC VOLTS, 6 V MAX,
30 END !100 µV RESOLUTION
In the following program, line 10 sets the number of PLCs to 1000. This
corresponds to maximum resolution (7.5 digits) and prevents %_resolution in line
20 from affecting the measurement. The requested resolution from line 20 is
10 μW. However. because of line 10, the actual resolution is 100 µW.
10 OUTPUT 722;"NPLC 1000" !SETS PLCS TO MAXIMUM
20 OUTPUT 722;"FUNC OHM,1E3,.001" !SELECTS 2-WIRE OHMS,
30 END !1 kW MAX, 10 mW RESOLUTION
ID?
Identity query. The multimeter responds to the ID? command by sending the
string "Keysight 3458A". This feature allows the GPIB controller to locate the
multimeter by its address.
