Non-Contacting Electrostatic Voltmeter for EOS and ESD Processes

Advanced Energy’s Trek 542A provides accurate electrostatic surface measurements. Typical uses include semiconductor, LCD, electronic assembly, and ESD-sensitive applications.

Measurement Range: ±20 kV DC or peak AC
Measurement Accuracy: Better than ±5% of the reading ±0.2% of full-scale over a probe-to-surface separation of 15 to 60 mm
Alphanumeric LCD Display: 20 x 4 characters

*Specifications dependent on model

Overview

The Trek® 542A electrostatic voltmeter (pictured with the Model 542P-S probe) is configured with a miniature electrostatic field chopper probe. The probe can be remotely located and easily positioned within process equipment to provide highly accurate, non-contacting, DC-stable, spacing-independent voltage measurements in either ionized or non-ionized environments. The unit’s 20 x 4 alphanumeric LCD screen displays the present measured voltage, positive and negative peak voltage values, and additional menu information.

Benefits

Enable drift-free measurements
Benefit from visual and audible alarms that activate when preset voltage-threshold levels are reached
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
Walking test adapter kit available
