Overvoltage Protection (OVP) is a feature that prevents excessive voltage from being applied to a device under test (DUT) connected to an SMU or power supply. When voltage output exceeds a certain limit, the device output shuts down and NI-DCPower generates an error.
To clear an OVP error condition, first identify and fix the
cause of the error and then use the niDCPower Reset VI or the niDCPower_Reset function.
