The Trek Model 344 is a precision electrostatic voltmeter for making noncontacting surface voltage measurements in the range of 0 to ±2 kV DC or peak AC.
The Model 344 employs a field-nulling technique for noncontacting voltage measurement that achieves DC stability and high accuracy even if the probe-to-surface spacing changes. This permits measurements of either stationary or moving surfaces without the need to establish fixed spacing to maintain accuracy.
The Model 344 patented probe design eliminates the need for close tolerance components. This significantly improves noise and drift performance, both in the presence of contaminating particulates and under conditions of high humidity and wide temperature ranges.
A precision voltage 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.
The Model 344 can be operated on a bench top or, with optional hardware, in a standard 19-inch rack. The rack adapter allows two 344 units to be mounted together.
The Digital Enable feature provides a connection for a remote device to turn on and off the high voltage of the instrument. This makes the 344 suitable for automated or computer-controlled systems.
The Model 344 is designed to be operated on a bench top.
