What is a Electrostatic field meter?
This instrument could be analogue or digital and is a portable device which is utilised to measure charges field on materials, people or machinery, it also assesses the polarity, this without touching the object, a common range in a field meter is +/-20KV to some +/-30KV, at a known distance from de object, say 1in, at a manufacturer’s specified tolerance, typically the box is made of a conductive material. Usually provides buttons for the hold and zeroing functions. As the distance from the measured object is difficult to assess a mechanism may be provided to aid. Grounding of the meter is achieved by the user using a wrist strap connected to ground with the same hand which is holding the device and operating the buttons as to do the measurements. They use batteries to operate.
