The CPM-766 is an advanced Charged Plate Monitor that utilizes a microprocessor for assessing the effectiveness of air ionizers in neutralizing static charge within ionization systems. It offers the capability to conduct positive and negative decay tests, as well as balance (offset voltage) tests, enabling the determination of the operational efficiency of an ionization system. Compliant with the ESD Association Standard ANSI/ESD STM3.1 and IEC 61340-4-7 Ionization, the CPM-766 is suitable for testing various types of ionization systems.
The CPM-766 conducts both manual and automatic decay and balance tests to qualify and periodically verify ionizers. Its internal memory is capable of storing up to 200 test data. The test data includes balance averages, temperature and humidity, date and time and can be saved under specified locations and areas.
The CPM-766 is equipped with a Li-ion battery pack that can be recharged through a USB connection. With a battery life of over 250 hours when in standby, it enables you to conduct around 1000 tests on average.
When operating in Decay mode, an internal high voltage generator is utilized to charge the plate to a voltage up of 1250 volts. During the test, the CPM-766 observes the duration required for the conductive plate to decay from 1000 volts to the stopping voltage selected by the user.
In the Balance mode, the Charged Plate Monitor will measure the offset voltage on the floating plate to determine an imbalance of positive and negative ions of an ionizer. An offset voltage threshold can be set to 35, 100 volts or 200 volts, where the information on the display during the test turns red to notify the user.
The CPM-766 provides the ability to perform automated Decay tests that can include a Balance test, in sequence. The number of Decay cycles and Decay sequences are determined by the user.
In Manual Operation you will be able to isolate the plate, charge the plate up to ±1,250 volts, ground the plate and control the timer for custom testing.
Using a large 5” color touchscreen LCD display, the CPM-766 displays clear, easy-to-use controls and a full keyboard that allows customization of labels, even while wearing gloves.
The CPM-766 is equipped with 2 standard ground jacks, an analog output jack, and a single USB-C port that provides connectivity to your PC for software updates and charging.
The 6” x 6” isolated plate is not detachable and cannot be removed.
