Measurement principle
The electrofieldmeter is a parametric operating amplifier. The influenced
charges, caused by the electrical field, generate an alternating current
proportional to the electrical field strength. The selective operating amplifier
measures the current without taking energy over the averaged time.
There are no radioactive components used inside the unit.

Calculating the electrical field strength
In order to compare to field strength measuring instruments, the shown
tension can be converted into the equivalent field strength. To do this, the
shown value has to be divided by the actual measuring distance (in meter).
Example:
Shown value:
2 kV
Actual measuring distance:
2 cm = 0,02 m
Calculated electrical field strength:
E = 2 kV/0,02 m = 100 kV/m
