CAUTION
It is important that these instructions be read and understood
before attempting to install or operate the equipment. Failure to
do so could result in serious personal injury and/or damage to
the equipment. At the end of this manual, a written warranty is
provided. This should be preserved carefully.

Notes to users
WARNING
This equipment is not constructed for classified hazardous environment. It cannot be used()
where it will be exposed to ignitable or corrosive materials and gases.
CAUTION
This equipment is intended for use in electrostatic processes that are free from water, oil,
solvent and other conductive contaminants. Exposure to such contaminantswillcausefailure
of the electrical insulation system in the product. Special care should be taken to ensure that
there is no dew formation. This equipment should be stored or used in a place less than
60 %RH.
Do not insert any object in the opening for the sensor located at the measuring side of the
instrument; no foreign substance should ever enter into the sensor opening.
This equipment should not be operated in an ambient with corrosive fumes of acid/alkali or
corrosive gases such as chlorine.
When not in use, please switch off the instrument.
This equipment must have proper grounding for accurate measurement.
This equipment is likely to be damaged by a fall. In such an event, it should be carefully
examined and any necessary repairs be made by an authorized technician. This is an
electronic instrument and contains sensor that is sensitive to mechanical vibrations and shock.
As it also contains a microcomputer chip and electronic circuitry it should not be used in an
environment where there is a lot of electromagnetic noise.
Suspend measurement when the voltage reading is outside the measuring range. If the value
is exceeds the range there is a possibility of damaging the sensor.
Do not exert any pressure on the LCD display from the top.
Clean the sensor plate and supported insulators for accurate measurement.
The equipment was assembled and inspected at Simco Japan, Inc. Do not attempt to
disassemble or modify its construction. If you are not clear about its operation and
maintenance, call Simco Japan's authorized agent in your area.

Section 1. General description
Simco-Ion Model EA-5J Charge Plate Monitor CPM is a compact instrument usedfor()
measuring the ionizer's performance. It is small, portable, handy and easytouse.
It was designed to provide quantitative, accurate measurements for a variety of air
ionization tests. It can be easily used for Discharge time Decay time and Ion Balance()
measurements for the ionizers. It is the most suitable for the routine inspection as a
support for the maintenance of ionizers, the selection and the evaluation of the ionizers
and soon.
It has a micro-computer inside and it is a multi-function instrument. Seven color button
switches placed on the surface make measurements easy.
There are two measurement modes such as Manual mode and automatic mode Auto(
mode .)
Manual mode is used for individual measurement Discharge time / Ion Balance.The()
measurement conditions can be changed by a SET button placed below LCD.
In Auto mode, both measurements of discharge time and ion balance can be done
automatically by pressing a Plate Control button once. The measurement conditions are
according as the set in the manual mode. After the measurements, each measuring data
can be memorized up to 1,000 by pressing a SAVE button. The saved data can be
down-loaded to a personal computer as CSV or TXT form using a USB cable. It will be
help for reduction of the input work to a personal computer of the measurement data.
A large digital LCD helps to confirm the measured value. The plastic enclosure must be
grounded using a grounding lead provided for accurate measuring.
