Trek PD04002A Charged Plate Monitor Controller - Manual

Model 04002A PD
Charged Plate Monitor Controller
Trek’s PD04002A versatile microprocessor based charged
plate monitor is ideally suited to monitor the performance of
air ionizers that are used in critical wide temperature
operations associated with semiconductor, LCD, electronic
assembly, and other processes where static charge
accumulations pose a threat to production yields and/or
product quality.
The Model PD04002A utilizes a new technique which requires
less than 0.1 picoampere of ion field current to achieve full
accuracy and stability. Other product designs require up to
2000 times more ion current to be drawn from the ion field to
achieve stability.
The ultra sensitivity of the Model PD04002A makes it the ideal
choice in air ionizer monitor applications where small area ion
collecting sensors are used to meet the requirement for high
accuracy ion balance measurement to levels of less than one
volt. The voltage of the charged plate is initialized prior to
discharge time testing. Balance tests, positive discharge
tests, and negative discharge tests can be initialized from a
remote location through digital command signals.
The charged plate voltage can be remotely monitored through
a rear panel connection. The voltage output at the Output “HI”
terminal in reference to the Output “LO” terminal (ground) is a
proportional buffered representation of the charged plate
voltage at a scale factor of 1 to 22 (other scale factors are
available). The Model PD04002A wide temperature range
charged plate monitor functions with standard, custom, or
high temperature charged-plates. The monitor and high-
temperature charged-plate can be used on a table top or
securely mounted by fasteners to the bottom of the unit.
