The Trek Model 706B portable electrostatic voltmeter is designed to perform highly accurate noncontacting surface electrostatic voltage measurements. Applications include measurement of photoreceptor surfaces in copiers and laser printers.
The Trek Model 706B E.S. [Electrostatic] Voltmeter provides measurement ranges of 0 to +1 kV or 0 to -1 kV (switch selectable) and employs an easy to read 3½ digit liquid crystal display to indicate the measured electrostatic voltage. Accurate electrostatic measurements can be performed over a probe to test surface spacing of 1 mm to 5 mm.
A voltage-nulling technique is employed in the Model 706B that achieves DC stability and high accuracy even if the probe-tomeasured surface spacing varies during use, this permits measurement of rotating electrophotography drums without concern for the effects of measurement accuracy due to drum eccentricities.
The probe design provides low noise and drift performance even in the presence of contaminating toner particles or under conditions of high humidity and temperature. The small durable probe has a cable length of 183 cm (72²).
The Model 706B is lightweight, battery operated, and packaged in a rugged enclosure that provides a convenient probe storage area.
