Usage
unitOfMeasure = smu.measure.unit
smu.measure.unit = unitOfMeasure
unitOfMeasure
The units of measure to be displayed for the measurement:
• Volts: smu.UNIT_VOLT (only available for voltage measurements)
• Resistance: smu.UNIT_OHM (only available for resistance measurements)
• Current: smu.UNIT_AMP (only available for current measurements)
•
Power: smu.UNIT_WATT (only available for voltage or current measurements)
Details
The change in measurement units is displayed when the next measurement occurs.
Example
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.unit = smu.UNIT_WATT
Changes the front-panel display and buffer readings for
voltage measurements to be displayed as power
readings in watts.
