Technical data
Description
The unit is housed into an EMV - plastic enclosure . The Influence Measuring Electrode is star
shaped. In front to it in a small distance apart a rotating grounded modulation propeller-wheel with
the them shape is located. The Influence Electrode is jacket by a ring electrode system used also
as mechanical shield for the propeller wheel and the sensor - plate. The measurement display is
located on top of the unit. It is an 2x12 digit alphanumeric LC - display.
The unit consists of a built in microprocessor for the following tasks as:
• it considers automatically the measured field strength (V/m) and the pre-selected distance
(cm) to calculate the voltage potential (Volt)
• single push - button control
• permanent Battery – voltage - control with automatic switch off
• CPS - mode

Operating instruction
Principle of operation
The Electro-Fieldmeter is working with a parametric amplifier. The charge caused by electrostatic
induction is converted to an alternating current proportional to the field strength.
A selective working amplifier measures the current without loss in relation to the field strength.
There is no use of any radioactive materials in the unit
Applications
Detection and control of electrostatic fields or charges.
Measuring: electric field strength electric charges, electrostatic charges, extremely high-resistent
voltage sources.
