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.
Model：520 Measurement Range
0 to ±2 kV DC.
Model 523 Measurement Range
0 to ±20 kV DC.
