Command notes (outputting voltage and current)

SENSe[1]:CURRent:RANGe <n>
SENSe2:CURRent:RANGe <n>
After specifying a current value, the instrument will go to the most sensitive range to
accommodate that reading. For example, if you are expecting a maximum current
reading of 750mA, you can let <n> = 0.75 (or 750e-3) to select the 5A range. Using the
:RANGe command to manually select a current range disables auto range. Another way
to select a range is to use the MINimum, MAXimum, and DEFault parameters as follows:
SENS:CURR:RANG MIN
SENS2:CURR:RANG MAX
SENS2:CURR:RANG DEF
The response for :RANGe? query returns the selected range value which is either 5.0000
or 0.0050.
SENSe[1]:CURRent:RANGe:AUTO <b> Applies to battery channel (#1)
SENSe2:CURRent:RANGe:AUTO <b>
This command is coupled to the :RANGe <n> command. When auto range is enabled,
the response for :RANGe? query returns the selected range value which is either 5.0000
or 0.0050. If you then disable auto range, the instrument will remain at the last selected
range.
[SOURce1]:VOLTage <n>
SOURce2:VOLTage <n>
This command sets voltage amplitude in volts: 0 to 15 (1mV resolution).
[SOURce1]:CURRent <n>
SOURce2:CURRent <n>
• With the 5mA measurement range selected, the maximum current limit is 1A.
• Sending a value that exceeds 1A is rejected, and the following message is displayed
briefly:
CURRENT LIMIT ON
mA RANGE ≤ 1A
