©2020 Advanced Energy Industries, Inc. The Trek® 347 non-contacting electrostatic voltmeter provides precise surface voltage measurements in the range of ±3 kVDC or peak AC. The Trek 347 utilizes a field-nulling technique for non-contacting voltage measurement that achieves DC stability and high accuracy, with no need for fixed probe-to-surface spacing. This permits the accurate measuring of stationary or moving surfaces. Patented probe design enhances noise and drift performance in the presence of contaminating particulate or under conditions of high humidity and/or wide temperature ranges. PRODUCT HIGHLIGHTS Superb noise and drift performance Precision voltage monitor output Monitor provides a low voltage replica of the measured electrostatic potential for monitoring purposes or for use as a feedback signal in a closed loop system Digitalenable allows an external device to turn the internal HV power supply on/off Well suited for automated or computer-controlled systems Easy-to-read LED display Large selection of optional probes offer versatility (order separately) Operated on a bench top, or with optional hardware, in a standard 19-inch rack NIST-traceable Certificate of Calibration provided with each unit TYPICAL APPLICATIONS Surface voltage measurements of photoconductors or dielectric surfaces Charge monitoring in semiconductor production Measuring of electrostatic potentials on film, polymers, and paper Measurement Range 0 to ±3 kVDC or peak AC Measurement Accuracy Better than ±0.05% of full scale Speed of Response Less than 3 ms for a 1 kV step (10 to 90%) AT A GLANCE TREK 347 Non-contacting electrostatic voltmeter provides precision and value for surface voltage measurements in the range of ±3 kVDC or peak AC.

Features
Zero Control A multi-turn control to produce zero volts output when the probe is coupled to a known zero volt surface Automatic Gain Control A ten-position push-button switch that adjusts the gain of the Trek 347 to optimize the AC response. The response control is normally adjusted when changing the type of probe being used or when changing the probe- to-surface separation. Digital Enable An open collector, TTL compatible input to turn on and off the internal high voltage power supply. A TTL high will turn off the high voltage. A TTL low will turn on the high voltage. 1Measured using the true rms feature of the Hewlett Packard Model 34401A digital multimeter
