Section 16: Verification procedure Model 6517B Electrometer Reference Manual16-8 6517B-901-01 Rev. C / August 2015Coulombs verificationCoulombs verification is performed by applying accurately known charge values (derived from avoltage source and capacitor) to the Model 6517B input jack, and then verifying that the Model 6517Breadings fall within specified limits.1. Connect the Model 6517B to the calibrator and capacitor as shown in the following figure, usingthe appropriate capacitor value from the standard capacitor column in the table below.Figure 137: Model 6517B coulombs verification
