Trek 542A Non-Contacting Electrostatic Voltmeter for EOS-ESD - Manual

Typical Applications Include
! Semiconductor
! LCD
! Electronic assembly
! ESD-sensitive processes
The T rek Model 542A Electrostatic Voltmeter (pictured at left
with the Model 542P-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 value, the negative peak
voltage value and additional menu information.
