Model 156A & Model 156A/1 CHARGED-PLATE MONITOR
The Trek Model 156A Charged-Plate Monitor System is designed
to provide quantitative measurements of the effectiveness of
air ionization systems, as to audit ionizer performance.
The Model 156A employs a revolutionary charged-plate monitor
design that utilizes an ultrahigh-impedance, high-voltage
follower to monitor the ion collecting plate voltage. This
technique provides very high accuracy and virtually infinite
impedance loading of the plate, while allowing the ion
collecting plate to be charged and monitored through the same
small-diameter connection. This technique also makes the
measurement capacitance independent of the physical size and
 shape of the ion plate. Therefore, the size and shape of an
 ion collecting plate, as well as the measurement capacitance,
 may be customer specified to match a particular ESD-sensitive
 device within a manufacturing process, or it may be made to
 conform to the EOS/ESD Association Standard STM3.1-2000.
The Model 156A features two modes of operation, a decay mode
with easy-to-program start and stop voltages, and a float mode. For decay mode operation, the ion collecting plate is precharged to a level above the programmed START voltage. The time required to discharge the ion collecting plate from the programmed START voltage to the programmed STOP voltage due to incident ion flow to the ion collecting plate from the measured ion field is indicated by the Model 156A. In the float mode of operation, the plate is initially discharged to zero and then allowed to float to the voltage level dictated by incident ion flow to the ion collecting plate from the measured ion field.
The simplicity of the design of the Model 156A makes it very
reliable and completely portable. The Model 156A is powered by
 an internal rechargeable battery that offers 8 hours of
operation from a full charge.
The Trek Model 156A/1 has a serial interface port to connect
with a computer. Computer Software allows the operator to
program test sequences, save, or retrieve test results. Any
series of tests can be duplicated, analyzed, programmed or
retrieved using PC based software.
