How do I Update the Voltage and Current Range on the WT100/WT200 Series Instrument Using IEEE488.2 Commands?

To change the voltage range on element 1 to the 30 V range, send the "RV4" command to the measuring instrument.
To change the current range on element 1 to the 1 A range, send the "RA5" command to the measuring instrument.

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

To query the voltage: "RV?"
To query the current: "RA?"

For information on the correspondence between voltage values, current values, and parameters, see the following:
