How do I Update the Voltage and Current Range on the Instrument Using Pre-IEEE488.2 Command Types?

To change the voltage range on element 1 to the 30 V range, send the "RV1,4" command to the measuring instrument.
To change the current range on element 1 to the 1 A range, send the "RA1,5" command to the measuring instrument.
To set the ranges on all elements at once, use: Voltage global setting "RV0,4" or Current global setting "RA0,5"

After entering settings, confirm the settings by sending the following commands:

  • To query the voltage on element 1: "RV1?"
  • To query the current on element 1: "RA1?" 

For more information on the correspondence between voltage values, current values, and parameters, please refer to:
