Using MEASure? for a Single Measurement
The following example uses the MEASure? command to make a single
ac current measurement. This is the easiest way to program the
multimeter for measurements. However, MEASure? does not offer much
flexibility. The example is shown in BASIC and QuickBASIC.
10 REAL Rdg
20 ASSIGN @Dmm TO 722
30 CLEAR 7 ! Clear GPIB and dmm
40 OUTPUT @Dmm; "*RST" ! Reset dmm
50 OUTPUT @Dmm; "*CLS" ! Clear dmm status registers
60 OUTPUT @Dmm; "MEASURE:CURRENT:AC? 1A,0.001MA" ! Set to 1 amp ac range
70 ENTER @Dmm; Rdg
80 PRINT Rdg
90 END
