MODEL 370 DC STABLE ELECTROSTATIC VOLTMETER
The Trek Model 370 is a precision electrostatic meter with the unique capability of making noncontacting surface voltage measurements in the range of 0 to ±3 kV DC or peak AC.
The 370 employs an electrostatic field-nulling technique which achieves high DC stability and high measurement accuracy even if the probe to measured surface spacing changes. This permits measurements of either stationary or moving surfaces without the need to establish fixed spacing to maintain accuracy.
An automatic gain feature of the Model 370 eliminates the need for manual adjustment when changing probes or when changing the probe to measured surface separation.
The Model 370 also features one-step, push-button zeroing. When the ZERO button on the front panel is pressed, the Model 370 automatically adjusts the output to zero volts when the probe is coupled to a known zero volt surface.
A precision voltage monitor provides a low-voltage representation of the measured electrostatic voltage for external monitoring purposes, or for use as a feedback signal in a closed-loop system.
An optional data acquisition module is available, featuring an IEEE-488 compatible interface, 14-bit resolution, 12-bit accuracy, and a programmable sampling period from 10 µs to 30 minutes.
The Model 370 can be operated on a bench top or, with optional hardware, in a standard 19-inch rack.
DATA ACQUISITION MODULE (OPTIONAL)Provides data output using an IEEE-488 compatible interface. PERFORMANCEAll specifications are with a 3800E-2 probe with a probe-to-surface separation of 2 mm unless otherwise noted. Measurement Range Measurement Accuracy Speed of Response (10% to 90%) Stability |
