To test the dc calibrator

To test the dc calibrator

The Aux Out BNC on the front panel is used for self-calibration and probe calibration. Though calibrator accuracy is not specified in the performance specifications, it must be within limits in order to provide accurate self-calibration.

Test Limits: -2.5 v to +2.5 v, Accuracy ±0.2% of delta voltage output
