model 520 series hand-held electrostatic voltmeter the model 520 series includes the model 520 and model 523.
the trek model 520 hand-held electrostatic voltmeter (esvm) series products provide accurate, noncontacting measurements of electrostatic surface voltage for esd applications in either ionized or non-ionized environments. industrial applications include measuring charge accumulation in the lcd manufacturing process or measuring static charge in semiconductor production. the model 520 series esvms utilize a new measurement technique that overcomes the disadvantage of the typical hand-held fieldmeter by providing surface voltage measurements which are essentially independent of the sensor probe-to-measured surface spacing. model 520-1 esvm over a spacing range of 5 mm to 25 mm, the 520 voltmeter provides better than a 5% voltage measurement accuracy, while the typical fieldmeter provides a voltage measurement error in excess of 50%. an optional voltage monitor output is available (model 520-2). model 523 esvm over a spacing range of 30 mm to 60 mm, the 523 voltmeter provides greater than a 5% voltage measurement accuracy, while the typical fieldmeter provides a voltage measurement error in excess of 50%.
the 520 series provides a measurement system which complies with standardized calibration equipment traceable to the national institute of standards and technology. the 520 series hand-held voltmeters employ a slender sensor probe design that provides flexibility to make measurements in many locations which are impossible to reach using the large, bulky sensing surfaces of the typical hand-held fieldmeter. the slender design also allows for higher spatial resolution capability by allowing the measurement of small surface areas. a hold pushbutton retains the displayed measured voltage value for recording purposes.
