Trek 541A Non-Contacting Electrostatic Voltmeter for EOS-ESD - Manual

Typical Applications Include
! Semiconductor
! LCD
! Electronic assembly
! ESD-sensitive processes
The T rek Model 541A Electrostatic Voltmeter (pictured at left with
the Model 541PR-S probe) provides accurate non-contacting
measurements of the electrostatic surface voltage associated
with EOS/ESD processes. The instrument is configured with a
miniature electrostatic field chopper probe that 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. A 20x4 alphanumeric LCD screen displays the
present measured voltage, the positive peak voltage, the negative
peak voltage and additional menu information.
