The Static Meter electrofield meter is a small hand-held field strength meter with digital display for measuring electrostatic charges in Volt. It perfectly combines easy operation with accurate measuring technique.
The Static Meter measures charges according to the field influence principle C: The influenced charges, caused by the electrical field, generate an alternating current proportional to the electrical field strength. The selective amplifier converts this value into the corresponding field strength or electrical potential – without withdrawing energy from the electric field over the averaged time.
A minimum voltage of 3600 volts is required to insure that a static elimination system is working. The Multicheck light will turn green if you have that voltage. AC Testers will NOT do this and are not an adequate indicator so be wary of marketing ploys which may offer AC testers as an accurate device for testing power supplies or static bars.
For testing power packs, the red measuring probe is inserted into the high-voltage socket as far as it will go. After pressing the red push button the LED will illuminate green if the unit functions correctly. In case of malfunction, the LED will illuminate in red or no display at all is visible
Hand Held Static 1 Digital Static Meter Model 80303 –
The Static 1 is a small hand-held field strength meter with digital
display for measuring electrostatic charges in Volts and is used if more
accurate readings are required than with the standard hand held meter.
In order to obtain optimum results, the distance between test object and
sensor head – depending on the degree of charge and the condition of
the objects’ surface – can be selected incrementally. The device is
equipped with a Hold function to keep the measured value stored on the
display. The integrated micro-computer automatically converts the
measured field
strength into the equivalent charge in Volt
Mode of Operation:
Field pattern of a uniformly charged film A and of a uniformly charged
film above the earthed/grounded metal plate B: The electric field of the
electrostatic charge is converted into a measuring alternating current
through the cyclical covering of the sensor plates. The display shows a
tension proportional to the intensity and polarity of the field to be
measured.
Field strength meters that work according to this principle have a high measuring sensitivity and allow very accurate measuring.
