Trek 323

Highly Sensitive, Versatile Electrostatic Voltmeter, Measure 0 to ±100 V

Advanced Energy's Trek 323 electrostatic voltmeter is ideal for highly sensitive voltage measurements and can be used with various side-view probes.

  • Measurement Range: 0 to ±100 V DC or peak AC
  • Accuracy: Better than 0.05% of full-scale
  • Speed of Response (10 to 90%): Less than 300 ms for a 100 V step (adjustable)

Overview

The Trek® 323 is a versatile instrument. Use in various electrostatic applications, including materials evaluation, electret studies, charge accumulation on disk drive assemblies, and other extremely sensitive ESD sensitive components.

The Trek 323 features adjustments to compensate for many sensitive testing conditions. Response speed control adjusts the speed/noise tradeoff of the AC response. And the drift/spacing null adjustment minimizes the variation in zero-offset voltages as the probe-to-test surface spacing changes. 

Benefits

  • Utilize low impedance probe sensor that assures high accuracy in high humidity and contaminated environments (e.g. airborne dust, toner, ions, and chemicals)
  • Monitor detected output voltage through a 1:1 voltage monitor output and a switch-selectable scale of 10:1 or 20:1 voltage monitor output
  • Use with various shaped probes (e.g. round, square)

Features

  • Sensitivity: 5 mV
  • Drift spacing/null adjustment
  • Response speed control
  • Additional probes available
  • CE compliant

  • Typical Applications

    • Materials evaluation
    • Electret studies
    • Charge accumulation on disk drive assemblies
  • EPA Regulation 40 C.F.R. 86.1312-2007

    The Model 323 meets the requirements described for an electrostatic monitor under the Environmental Protection Agency (EPA); Title 40 Part 86 – Control of Emissions from New and In-Use Highway Vehicles and Engines. Specifically 40 C.F.R. 86.1312-2007 - Filter stabilization and microbalance workstation environmental conditions, microbalance specifications, and particulate matter filter handling and weighing procedures.

    This EPA regulation for emission control describes the procedure for measuring particulates from vehicle emissions that are accumulated on a filter for weighing. During the weighing process static neutralizers such as Po-210 sources are used to neutralize any charge build up on the filter that could interfere with the filter weighing. To insure the Po-210 sources (or other static neutralizers) are operating properly a static monitor is used to measure residual charge on the filter before weighing. Static charge on the filter needs to be less than ±2V DC which requires the use of a static measuring device having sufficient low voltage resolution, low zero offset, and good sensitivity. The Model 323 with 0.01V of resolution and 5mV of sensitivity meets these requirements to insure accurate and repeatable measurements required by EPA regulation 40 C.F.R. 86.1312-2007.
