How to perform “Individual Calibration”?

The advantage of doing the individual calibration is that you can, without doing a new calibration, switch between doing an electrical measurement, measure with amplifier and measure with transducer.

If you are not already in the Output level calibration dialog box, go to Measurement->Calibration…, click the  button to the right of the Use output calibration check box is shown below

In the dialog, follow each step to complete the calibration. E.g. in step 2, you must select Individual as shown below.
