The Trek Model 323 Electrostatic Voltmeter performs highly

sensitive voltage measurements using a variety of Trek side-

view probes with various body types (round, square).

The Model 323 is a versatile instrument used for a variety of

electrostatic applications including materials evaluation,

electret studies, charge accumulation on disk drive

assemblies, and other extremely sensitive ESD sensitive

components.

The Model 323 is specifically designed for high sensitivity

applications and performs highly accurate, noncontacting

measurement of electrostatic potentials of 0 to 100 V over a

wide range of probe-to-surface distances.

The Model 323 has adjustments to compensate for many

sensitive testing conditions. The response Speed control

adjusts the speed/noise tradeoff of the AC response. The

Drift/Spacing Null Adjustment

Trek patented low impedance probes assure measurement

accuracy essentially independent of probe-to-test-surface

spacing, humidity conditions, and contamination such as

airborne dust, toner, ions and chemicals.

minimizes the variation in zero

offset voltage as the probe to test surface spacing changes.

The front panel has an easy to read 3½ digit LED display. The

detected output voltage can be monitored through a 1:1

voltage monitor output and a switch selectable scale of 10:1

or 20:1 voltage monitor output.
