[295475] Study of Intermediate Checking of the Calibration of Electrometers with Capacitors
Autores: Liana Machado, Ricardo Amorim Barbosa
Resumo: In this article we will show the performance of electrometers when the current source came from a capacitor. This device is called “capacitance current source”. We use a QuadTech capacitor of 1000 pF and a voltage of 1V. The performance of the electrometers was very different. One of the electrometers was tested with the “earth button” on at the FLUKE 5500A calibrator; and your performance was better. The measurements were made manually. It is possible that, with the automation of measurements, the performance of electrometers, for the intermediate checking of calibration, will reach a value not yet seen in this study.
