Trek 370

Precision, Non-Contact Electrostatic Voltmeter

Advanced Energy's Trek 370 stable electrostatic voltmeter features the unique capability to take non-contact surface voltage measurements in the range of 0 to ±3 kV DC or peak AC.

  • Very High Speed of Response: Less than 50 ms for a 1 kV step
  • Measurement Range: 0 to ±3 kV DC or peak AC
  • Measurement Accuracy: Better than 0.05% of full-scale

Overview

The Trek® 370 employs an electrostatic field-nulling technique to achieve high DC stability and high measurement accuracy — regardless of probe-to-measured surface spacing changes. This permits highly accurate stationary or moving-surface measurement without fixed-spacing. An automatic gain feature eliminates the need for manual adjustment when changing probes or probe-to-surface distance. A precision voltage monitor provides low voltage representation of the measured electrostatic voltage for external monitoring purposes, or use as a feedback signal in a closed-loop system.

Benefits

  • Eliminate the need for manual adjustment with automatic gain feature
  • Operate on a benchtop or, with optional hardware, in a standard 19-inch rack
  • Add optional data acquisition module that features and IEEE-488 compatible interface, 14-bit resolution, 12-bit accuracy, and a programmable sampling period from 10 µs to 30 minutes
  • Utilize one-step, push-button zeroing
