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
Equipment Required
Procedure
1
Connect the multimeter to the front panel Aux Out BNC.
Use the BNC cable and the BNC to banana plug adapter.
2 Enable the graphical interface.
Use the mouse to click on the button in the upper right-hand corner of the display. See figure 3-1.
