niDCPower commit VI should change the range when output is in the off state

Status: Declined

Any idea that has not received any kudos within a year after posting will be automatically declined.

Measure range is not commited to SMU instrument while the output is in off state. niDCPower commit VI should change range of device even when output is in off state.

 

In cases where UUT has external voltage applied to it, SMU device will give an overvoltage error even if UUT voltage is within SMU voltage range. This occurs due to the range settings not being commited when the output has been turned off.

I'd call that a bug

I think you have to do a DCPower initiate to apply range changes.
