smu.measure.autorangehigh
When autorange is selected, this attribute represents the highest measurement range that is used when the
instrument selects the measurement range automatically.

Details
This command can be written to and read for resistance measurements. For current and voltage
measurements, it can only be read.
For current and voltage measurements, the upper limit is controlled by the current or voltage limit.
For resistance measurements, you can use this command when automatic range selection is enabled
to put an upper bound on the range that is used for resistance measurements.
The upper limit must be more than the lower limit.
If the lower limit is equal to the upper limit, automatic range setting is effectively disabled.
Example
smu.measure.func = smu.FUNC_DC_VOLTAGE
smu.measure.autorange = smu.ON
print(smu.measure.autorangehigh)
Sets the measurement function to voltage and turn
autorange on. Check the high range for voltage
measurements.
