3 Product Description
1. Product Description
The Charge Plate Monitor CPM 374 with its built-in timer function consists of a high voltage unit
and an electrostatic field meter. Therefore it has an input resistance of 10 16
Ω
and is suited for
measuring static potentials and discharging times of air ionizers.
The CPM 374 corresponds to DIN EN 61340-5-1 and EOS/ESD S.3.1.
For measuring vertically the enclosed distance bolts have to be used.
Important: The high voltage unit is protected by high impedance and therefore touch-proof.
By the use of battery power and its compact design the CPM 374 is perfectly suited for mobile
application. Of course it can be operated by using the provided wall power supply. As the CPM
374 is menu-driven and operated by 2 pushbuttons the device is very user-friendly. For a better
orientation the selected parameters are displayed in the double-spaced LCD display.
The device can be operated computer-controlled by use of the provided Excel software.
