Details
When auto clear is set to on for a measure function, limit conditions are cleared automatically after
each measurement. If you are making a series of measurements, the instrument shows the limit test
result of the last measurement for the pass or fail indication for the limit.
If you want to know if any of a series of measurements failed the limit, set the auto clear setting to off.
When this set to off, a failed indication is not cleared automatically. It remains set until it is cleared
with the clear command.
The auto clear setting affects both the high and low limits.
Example
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.limit[1].autoclear = smu.ON
Turns on autoclear for limit 1 when
measuring DC current.
