Basic Electrostatics System
Model No. ES-9080
12
!
Five binding posts allow the voltage source and/or the electrometer to
be connected to components.
Electrometer Operation and Setup
Requirements
The controls on the front panel of the electrometer are explained in
Figure 1. Whether you are using the electrometer to measure voltage,
current or charge, the setup procedure should be followed each time
you turn on the electrometer.
Warning:
To avoid electrical shock and/or injury, observe the following safety
precautions:
1.
Never use the electrometer for measuring potentials more than 100
volts.
2.
Never connect the electrometer to an electrostatic generator, such as
a Van de Graff generator of a Wimshurst machine.
3.
Never touch the input leads until you have grounded yourself to an
earth ground. A person walking across a rug on a cool, dry day can
easily acquire a potential of several thousand volts.
Setup
1.
Before turning on the electrometer, check to ensure that the meter reads
zero. If not turn the Mechanical Zero Adjust screw, located just below
the electrometer face, until it does.
2.
Connect the test lead to the input connector of the electrometer.
3.
Connect the ground post of the electrometer to an earth ground.
4.
Push the power button ON. One of the range switch LEDs will
blink twice in quick succession.
5.
To zero the meter, press the ZERO button. You’re now ready to use
the electrometer to measure charge, current or voltage.
6.
Set the range switch to the desired voltage range. The range setting
refers to the voltage input required to produce a full-scale meter
