smuX.reset
Function Turns off the output and resets the SMU to the default settings.
Usage smuX.reset()
Returns the SMU to the default settings listed in

smuX.sense
Attribute Remote/local sense mode.
Usage sense = smuX.sense
smuX.sense = sense
Set

Remarks • Source-measure operations are performed using either 2-wire local sense connections or
4-wire remote sense connections. Writing to this attribute selects the sense mode.
The
• smuX.SENSE_CALA mode is only used for calibration and may only be selected
when calibration is enabled.
• The sense mode can be changed between local and remote while the output is on.
• The calibration sense mode cannot be selected while the output is on.

smuX.source.autorangeY
Attribute Source auto range control (on/off).
Usage sautorange = smuX.source.autorangeY -- Reads source auto range.
smuX.source.autorangeY = sautorange -- Writes source auto range.
Set autorange to one of the following values:
or
0 smuX.AUTORANGE_OFF
or
1 smuX.AUTORANGE_ON
Remarks • This attribute indicates the source auto range state. Its value will be
smuX.AUTORANGE_OFF when the SMU source circuit is on a fixed range and
smuX.AUTORANGE_ON when it is in auto range mode.
• Setting this attribute to smuX.AUTORANGE_OFF puts the SMU on a fixed source range.
The fixed range used will be the range the SMU source circuit was currently using.
• Setting this attribute to smuX.AUTORANGE_ON puts the SMU source circuit into auto
range mode. If the source output is on, the SMU will immediately change range to the
range most appropriate for the value being sourced if that range is different from the SMU
range.
• Auto range will disable if the source level is edited from the front panel.
