| Zusammenfassung | A new calibration setup for picoamperemeters is presented. Owing to the use of a novel voltage ramp generator with increased linearity, the useful measuring time is increased to about 35 min, which reduces the calibration uncertainty of picoamperemeters with long time constants. |
