How do I Update the Voltage and Current Range for the PZ4000 and WT1600 Using Communication Commands?

To change the voltage range on element 1 to 30 V, send the "INPUT:VOLTAGE:RANGE:ELEMENT1 30V" command to the measuring instrument.
To change the current range on element 1 to the 1 A range, send the "INPUT:CURRENT:RANGE:ELEMENT1 1A" command to the measuring instrument.

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

  • To query the voltage on element 1: "INPUT:VOLTAGE:RANGE:ELEMENT1?"
  • To query the current on element 1: "INPUT:CURRENT:RANGE:ELEMENT1?" 

To set/query the ranges on all elements at once, use the following commands:

  1. Voltage global setting
    "INPUT:VOLTAGE:RANGE 30V"
  2. Voltage global query
    "INPUT:VOLTAGE:RANGE?"
  3. Current global setting
    "INPUT:CURRENT:RANGE 1A"
  4. Current global query
    "INPUT:CURRENT:RANGE?

For information on the voltage and current values that can be set using these commands, please refer to:
