Model 6517B Electrometer Reference Manual Section 15: Calibration procedure
6517B-901-01 Rev. C / August 2015 15-15
Current offset partial calibration
It is recommended that all calibration steps be performed if performing individual current offset steps.
If a single current offset step is performed, the ranges affected by the voltage offset calibration require
re-calibration before a valid calibration can be saved.
Ranges affect by partial current offset calibration
Current offset step
performed Ranges that require recalibration
1 All current ranges except 20 pA and 200 pA
2 20 pA and 200 pA current ranges
3 2 nC and 20 nC charge ranges
4 200 nC and 2 uC charge ranges
5 2 V, 20 V, and 200 V voltage ranges
Current ranges partial calibration
If an individual current range of the Model 6517B is calibrated, the three steps corresponding to a
single current range need to be performed:
1. Calibration of the range zero.
2. Calibration of the positive full scale range.
3. Calibration of the negative full scale range.
Voltage ranges partial calibration
If an individual voltage range of the Model 6517B is calibrated, the three steps corresponding to a
single voltage range need to be performed:
1. Calibration of the range zero.
2. Calibration of the positive full scale range.
3. Calibration of the negative full scale range.
Charge ranges partial calibration
If an individual charge range of the Model 6517B is calibrated, the four steps corresponding to a
single charge range need to be performed:
1. Starting the positive full scale calibration step.
2. Calibration of the positive full scale range.
3. Starting the negative full scale calibration step.
4. Calibration of the negative full scale range.
