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
- Technical Specs
- Service & Support
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.
- Eliminate the need for manual adjustment with automatic gain feature
- Operate on a benchtop or, with optional hardware, in a standard 19-inch rack
- Utilize one-step, push-button zeroing
- Automatic gain
- Zero control
- Voltage monitor output
- Electrostatic field-nulling technique
