Charge Plate Monitor CPM 374

The Charge Plate Monitor CPM 374 measures the voltage potential on its integrated plate electrode according to the fieldmill influence principle. The device is suitable to determine the static decay time from a selected higher voltage threshold to a lower voltage threshold level. It consists of a integrated timer, a high voltage unit and a electro fieldmill sensor and achieves therefore the high impedance of 10 15 ? to measure electrostatic voltage potentials and static decay times of air ionizer equipment.

The unit complies to EN 61340-5-1 and EOS/ESD S.3.1

The high voltage unit is protected by a high-ohmic resistor and therefor touch safe.

The CPM 374 is battery powered and due to its compact design, it is very suitable for the mobile use in industrial areas. It can also be run on the power supply (230/115 VAC). The CPM 374 is menu-driven and controlled by means of 2 switches for simple operation. All selected parameters are shown in the 2-line LC-display for a better orientation of the operator.
