FMX-004 5201236 Rev.A
2. INTRODUCTION
The FMX-004 Electrostatic Fieldmeter is a compact instrument used for measuring
electrostatic potentials. It is compact (pocket size), portable, handy and easy to use.
The FMX-004 has a micro-computer inside. The fieldmeter can be turned on/off by a push
button POWER switch (red). A grey push button switch marked ZERO is used for zero
adjustment. A green push button switch marked HOLD holds the display and is especially
useful where the display is difficult to see during a measurement.
Model FMX-004 can correctly measure static voltages within 30 kV (30,000V) range at
a distance of 1” (25 mm). Two LED guide ring lights are provided on the sensor side of
the unit to help position the instrument at the right distance from a charged object. The
conductive case and ground lead facilitate grounding for proper measurement. Whenever
the MODE button is pushed, the measurement mode is revocable.
Model FMX-004 can be used for static voltage as well as Ion Balance voltage
measurements. By attaching the Ion Balance charge plate to the top of the unit then
pushing the blue button marked IB, the unit will switch to Ion Balance mode. Here, ion
balance voltage measurement can reach up to ±300V.
The compact design of this unit makes measurements easy and usable in relatively
inaccessible work areas. It can be used in various applications such as deciding the
location of static eliminators, investigating static charge levels, deciding the need for
charge neutralization, as a support for the maintenance of static eliminators, etc.
