Measuring principle
The electrostatic field meter is a parametric amplifier. The electric field influences a current
proportional to the electrostatic field. The current is amplified and measured with a selective
amplifier. No energy is taken from the field over time means.
No radioactive matters are used!
Application Areas
Detection
and
Control
of electrostatic fields resp. charges,
measuring
of electric charges, electro-
static charges, very high-resistance voltage sources.
Button Features
On
Press «function/on» 1 time briefly
Hold
Press «function/on» 1 time briefly to switch on or off
Distance
Press «function/on» until „change cm“ appears
Press «function/on» 1 time briefly to change to a new distance or to CPS mode,
wait approx. 2s to select the displayed function
Aus
Press «function/on» 2 times in quick succession
Initiation
By pressing the «function/on» button on the front panel the device is switched on. By pressing
the «function/on» button twice in normal operation the device is switched off.
The black cover cap on the modulator system has to be removed before measuring!
If the «function/on» button is not pressed for about 3.5 min, the device switches off to save
power and to prevent discharge of the accumulator.
Hold
The device has a hold function to freeze the current measuring value. By pressing the
«function/on» one time the value measured at that time remains in the display. The upper line
shows „Hold“ and in the bottom line the result is displayed. By pressing the «function/on» but-
ton again the hold function is switched off and the current result is displayed.
