Programming example — range and digits

The following command sequence selects the 200V range and sets display resolution to 3:

*RST ‘ Restore RST defaults.

VOLT:RANG 200 ‘ Set V function to 200V range.

DISP:DIG 3.5 ‘ Set display resolution to 3½ digits.

Commands Description Default

:CURRent Measure current:

:RANGe Range selection:

[:UPPer] <n> Specify expected reading; -0.021 to 0.021 (A). 200µA

: AUTO <b> Enable or disable autorange. (see Note)

:ULIMit <n> Specify upper range limit for autorange; -0.021 to 0.021 (A). 20mA

:LLIMit <n> Specify lower range limit for autorange; -0.021 to 0.021 (A). 20pA

:RESistance Measure resistance:

:RANGe Range selection:

[:UPPer] <n> Specify expected reading; 0 to 2.1e11 (Ω). 200kΩ

: AUTO <b> Enable or disable autorange. (see Note)

:ULIMit <n> Specify upper range limit for autorange; 0 to 2.1e11 (Ω). 200GΩ

:LLIMit <n> Specify lower range limit for autorange; 0 to 2.1e11 (Ω). 2kΩ

:CHARge Measure charge:

:RANGe Range selection:

[:UPPer] <n> Specify expected reading; -21e-6 to 21e-6 (C). 200nC

: AUTO <b> Enable or disable autorange. (see Note)

:LGRoup <name> Select autorange group; HIGH or LOW HIGH

For Digits:

DISPlay DISPlay Subsystem:

:DIGITs <n> Set display resolution; 4 to 7, where: 6

4 = 3½-digit resolution

5 = 4½-digit resolution

6 = 5½-digit resolution

7 = 6½-digit resolution

Note: Rational numbers can be used. For example, to set 4

resolution, send a value of 4.5 (the 6514 rounds it to 5).

Note: *RST default is ON and SYSTem:PRESet default is OFF.
