An Electrometer Design and Characterization for a CubeSat Neutral Pressure Instrument
… of an ionization chamber and a logarithmic electrometer circuit. The Rev. 1 SNeuPI electrometer prototype does not function as designed. A Rev. 2 electrometer circuit must be designed and its performance characterized across specified operating temperature and input current ranges. This …

Advanced Faraday cage measurements of charge, short-circuit current and open-circuit voltage
… electrode of the electrode chamber with the electrometer, as water condensed. Positive current could have been produced by the evaporation of moisture from the center electrode of the electrode chamber. Dew point analysis is performed to show that for water to condense on metallic surfaces, …

Developing a labview based thermally stimulated current (tsc) controller to measure residual charge in electrospinning
… controller encapsulates the temperature and the electrometer control using RS- 485 and GPIB interfaces. The controller outputs a Temperature-Current plot which is the Thermally Stimulated Current spectrum. The current observed at the melting point of the electrospun material is a direct measure …

Characteristics of particles downstream of a partially failed diesel particulate filter.
… An electrostatic precipitator, DMA, electrometer and CPC were used to evaluate the aerosol charge distribution. Downstream measurements were repeated as the filter was progressively failed in a series of steps. These measurements were then used to evaluate the response of the …

Single-layer transport measurements of bilayer 2D electron and hole systems in GaAs heterostructures
… (2DES), we use the lower 2DES as a quantum Hall electrometer to measure the chemical potential of the upper 2DES. We track the evolution of the Landau levels in the upper 2DES, and extract an effective mass that is consistent with previous values. Secondly, we investigated the hysteresis in the …

The Influence of Food Physical Properties on Transfer Efficiency and Adhesion in a Tumble Drum Process
… exiting the test cell was measured using an electrometer (Model 614, Keithley Instruments, Inc., Cleveland, OH) and theresistivity was determined by the following equation: ¿ = (KV)/I, where ¿= resistivity, K is the cell constant which is equal to 0.014, V= the voltage applied to the test …

Particle Charging and Classification: The Mass Mobility Aerosol Spectrometer (M2AS)
… address this challenge, the Mobility Separator Electrometer (MSE) is introduced—a new classifier designed to measure average charge and average particle electrical mobility when combined with a condensation particle counter (CPC). The MSE enhances the performance of unipolar charger-classifier …
