Section 6: SCPI command reference
When the zero output-off state is selected, when you turn off the output:
• The measurement sense is changed to 2-wire sense
• The source function is set to voltage
• The source voltage is set to 0
Set the range to the presently selected range (turn off autorange)
•
• Program the voltage DAC to zero, and the current DAC to full scale of the present current range.
When the zero output-off state is selected, you can use the instrument as an ammeter because it is outputting
0 V.
When the guard output-off state is selected and the output is turned off, the following actions occur:
• The measurement sense is changed to 2-wire sense
• The current source is selected and set to 0 A
• The voltage limit is set to 10% full scale of the present voltage range
If you send this command without the <function> parameter, it will set the output-off state for all
functions.
