smuX.measure.autorangeY
X = SMU channel (a or b)
Y = SMU measure function (v or i) where v = voltage, i = current
Attribute Measure auto range setting.
Usage autorange = smuX.measure.autorangeY -- Reads measure auto range.
smuX.measure.autorangeY = autorange -- Writes measure auto range.
Set autorange to one of the following values:
0 or smuX.AUTORANGE_OFF Disables measure auto range.
1 or smuX.AUTORANGE_ON Enables measure auto range.
Remarks
• This attribute indicates the measurement auto range state. Its value will be
smuX.AUTORANGE_OFF when the SMU measure 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 range. The
fixed range used will be the range the SMU measure circuit was currently using.
• Setting this attribute to smuX.AUTORANGE_ON puts the SMU measure circuit into auto
range mode. It will remain on its present measure range until the next measurement
is requested.
Details See “Range” in Section 6.

Example
Enables voltage measure autoranging for SMU A:
smua.measure.autorangev = smua.AUTORANGE_ON
smuX.measure.autozero
X = SMU channel (a or b)
Attribute Behavior of the SMU’s A/D internal reference measurements (autozero).
Usage
azmode = smuX.measure.autozero -- Reads autozero.
smuX.measure.autozero = azmode -- Writes autozero.
Set azmode to be one of the following values:
0 or smuX.AUTOZERO_OFF Autozero disabled.
1 or smuX.AUTOZERO_ONCE Performs autozero once, then disables autozero.
2 or smuX.AUTOZERO_AUTO Automatic checking of reference and zero
measurements. An autozero is performed when
needed.
