Model No. ES-9080 Basic Electrostatics System

deflection (e.g., a setting of 30 means that a full-scale meter

deflection indicates a voltage of 30 volts).

Important Points for General Operation:

1. Between measurements, always press the Zero button to discharge all

current from the electrometer.

2. Shorting the test leads together is insufficient. There may still be

stray charges within the electrometer circuitry.

3. For good results, it is essential that the electrometer be connected to

an earth ground (a water pipe or the ground wire from a 120 VAC

socket). Only an earth ground provides a sufficient drain for excess

charges that may build up during an experiment. It is also helpful if

the experimenter is grounded. Just touch one hand to a good earth

ground just before, or during measurements.

More information on taking accurate measurements is provided in the

demonstrations on pages 14-34.
