706A/1 PORTABLE Electrostatic Voltmeter
The Trek Model 706A/1 portable electrostatic voltmeter is specifically designed as a field-service tool to perform ESD noncontacting surface voltage measurements. Applications include measurement of photoreceptor surfaces in copiers and laser printers. The Trek Model 706A/1 portable electrostatic voltmeter has a measurement range of 0 to +1 kV or 0 to -1 kV (switch selectable) and employs an easy to read 3? digit liquid crystal display to indicate the measured electrostatic potential in volts. Accurate electrostatic measurements can be performed by holding the probe at a distance of 1 mm to 5 mm from a surface.? Model 706A/1 employs a voltage-nulling technique that achieves DC stability and high accuracy even if the probe-to-measured surface spacing varies during use. For example, this permits measurement of rotating electrophotography drums without concern for the effects of measurement accuracy from drum run-out. 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 (72").? The Model 706A/1 is lightweight, battery operated, and packaged in rugged enclosure that provides a place for convenient probe storage.? ?
