Abstract:
A method for calibrating a test instrument having an initial output voltage level and an open output relay can include programming the test instrument for a certain current level, starting a timer, and stopping the timer (responsive to the test instrument entering compliance) to determine a time interval. The method can also include determining whether the time interval is within a desired range.
