Trek Model 520 Series Hand-Held Non-Contacting Electrostatic Voltmeters The Trek Model 520 (±2kV) and Model 523 (±20kV) Hand-Held Electrostatic Voltmeters provide accurate, noncontacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments. These two voltmeters utilize a measurement technique that overcomes the disadvantage of the typical hand-held field-meter by providing surface voltage measurements which are essentially independent of the sensor probe-to-measured surface spacing. Model 520 is available in two versions. The 520-1 has a digital meter to display the measured voltage. The 520-2 has an analog output monitor in addition to the digital display. This analog output monitor can be used to record the measured voltage or to view it on an oscilloscope. Model 520 Key Specifications . Measurement Range: 0 to ±2 kV DC . Measurement Accuracy: Better than ±5% of full scale over the entire recommended probe-to-surface separation range of 5 mm to 25 mm . Speed of Response (10% - 90%): Less than 25 ms for a 0 to ±2 kV input step change (520-2 Voltage Monitor Output) Model 523 Key Specifications . Measurement Range: 0 to ±20 kV DC . Measurement Accuracy: Better than ±5% of full scale over the entire recommended probe-to-surface separation range of 30 mm to 60 mm . Sampling Rate: 2.5 readings per second Typical Applications Include . Measurement of electrostatic surface charge build up • Manufacturing processes • Electronic assembly testing • Semiconductor material testing • Dissipative material testing • Automotive electronics testing • ESD Auditing and troubleshooting Features and Benefits • Accurately measures surface voltage at a wide range of spacings • No need to maintain a fixed spacing • Chopper stabilized for drift-free operation in ionized environments • NIST-traceable Certificate of Calibration provided with each unit . compliant TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com • sales@t
