10.
Press ENTER. Model 6514 will prompt for the negative full-scale charge value:
-20.0000nC
11.
Set the calibrator output voltage to -20.00000V. Calculate the actual charge from the cal-
ibrator voltage and actual standard capacitor value: Q = CV. Adjust Model 6514 display
to agree with the calculated charge value, then press ENTER to complete calibration of
the present range.
12.
Press EXIT to return to normal display.
13.
Repeat steps 4 through 12 for the 200nC through 20
µ
C ranges using Table 19-6 as a
guide.

Based on nominal capacitance values. Calculate actual charge from calibrator voltage and actual standard
capacitance value: Q = CV. Calibrate positive full-scale, and negative full-scale values for each range.
