Smux.measure.autozero - Keithley 2601B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
Details
This attribute indicates the measurement autorange state. Its value is smuX.AUTORANGE_OFF when the SMU
measure circuit is on a fixed range and smuX.AUTORANGE_ON when it is in autorange mode.
Setting this attribute to smuX.AUTORANGE_OFF puts the SMU on a fixed range. The fixed range is the present
SMU measure range.
Setting this attribute to smuX.AUTORANGE_ON puts the SMU measure circuit in autorange mode. It remains on
its present measure range until the next measurement is requested.
If source highC mode is enabled, current autorange is set to smuX.AUTORANGE_FOLLOW_LIMIT and cannot be
changed.
Example
smua.measure.autorangev = 1

Recall setup
Indicates status of autozero; set to 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
Source-measure unit (SMU) channel (for example, smua.measure.autozero
applies to SMU channel A)
Section 7: TSP command reference
Enables voltage measurement autoranging for SMU
channel A. Alternatively, the value 1 may be replaced with
smua.AUTORANGE_ON.
