• Notes

• An Electrometer, in essence, is a multimeter with an incredibly high input impedance. In this case, in the order of 10¹² Ω, or 1TΩ. This electrometer has a digital readout unit with nixie tubes, made by Analogic, 2000 counts and a +/- sign.

  This electrometer can measure Voltage, Resistance, Current and Charge, in the following settings:

  DC Voltage ranges: 0.2V, 2V, 20V, 200V

  Resistance ranges: 2×10⁵ - 2×10¹² Ω (in steps 10×)

  Current ranges: 2×10⁻¹² - 2×10⁻² A (in steps 10×)

  Charge ranges: 2×10⁻¹º - 2×10⁻⁷ C (in steps 10×; 1C = 1 coulomb = 1 ampere×second)
