A Keithley picoammeter is used to measure the leakage current of a GEM foil
Unfortunately, the Keithley can be damaged if I sees a potential difference of 240 Volts or more.
The Circuit below is designed to protect the Keithley in case the GEM foil capacitor becomes a direct short during the measurement.
