Trek 541A

Non-Contacting Electrostatic Voltmeter for EOS and ESD Processes

Advanced Energy's Trek 541A provides highly accurate, non-contacting, DC-stable, spacing-independent voltage measurements in either ionized or non-ionized environments. Typical uses include semiconductor, LCD, electronic assembly, and ESD-sensitive applications. 

  • Measurement Range:
    • 541A-1: ±1 kV DC or peak AC
    • 541A-2: ±100 V DC or peak AC
  • Measurement Accuracy: Better than ±1% of full scale over a probe-
    to-surface separation of 2.5 mm ±1 mm
  • Alphanumeric LCD Display: 20 x 4 characters

Overview

The Trek® 541A (pictured with the Model 541PR-S probe) electrostatic voltmeter is configured with a miniature electrostatic field chopper probe. The probe can be remotely located and easily positioned within process equipment. The unit's 20 x 4 alphanumeric LCD screen displays the present measured voltage, positive and negative peak voltage values, and additional menu information. Visual and audible alarms activate when preset voltage-threshold levels are reached.

Benefits

  • Enable drift-free measurements
  • Remotely locate or easily position miniature field chopper probe
  • Use in ionized or non-ionized environments
  • Take spacing-independent voltage measurements

 

 

Features

  • Chopper probe is DC-stable with or without incident airflow
  • Analog voltage monitor output
  • USB and RS-232 serial ports
  • NIST-traceable calibration certificate provided with each unit
