Section 1. GENERAL DESCRIPTION
Simco-Ion Model FMX-004 Electrostatic Fieldmeter is a
compact instrument used for measuring electrostatic
potentials. It is small (pocket size), portable, handy and
easy to use.
It 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.
Simco-Ion Model FMX-004 can correctly measure static
voltages within 30 kV (30,000 V) range at a distance of±
25 . 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 revokable.
Model FMX-004 can be used for static voltage as well as
Ion Balance voltage measurements. Ion balance voltage
measurement to 300 V is possible by attaching a Ion±
Balance Plate and using a light blue push button switch
marked IB. The plate can be kept attached to either end of
FMX-004 when not in use.
Compact design of this unit makes measurements easy and
usable in relatively inaccessible work areas. It can be used
in various applications such as in deciding the location of
static eliminators, in investigating static charge levels, in
deciding the need for charge neutralization, as a support for
the maintenance of static eliminators etc.

5.1 Grounding connection
The accuracy might be affected by the static charge on the person making
the measurement if FMX-004 is ungrounded. For proper measurement,
the operator should be grounded using a wrist strap and/or FMX-004 shall
be grounded on the right side grounding socket by the grounding lead
provided with the equipment.
CAUTION
The plastic case of FMX-004 is made of conductive resin. The
grounding terminal provides the reference potential for the electrical
circuit. This terminal should be grounded properly for proper
measurement. If it is not properly grounded, the accuracy is not
guaranteed.
5.2 Selection of the measurement mode
There are 4 modes of operation based on whether Auto-off function is
operative or not.
5.2.1 Standard mode for static charge (voltage) measurement
Press the center of red circle button switch marked "POWER" once①after turning the sensor of FMX-004 toward an uncharged area. A
single beep (0.25 second) sounds once to inform that FMX-004 is
into standard mode.
As the power is turned on, LCD display shows digital numerical②value, polarity sign, unit of measurement "kV", bar graph scale and
battery condition. At this time, please confirm the state of the battery
from "Battery condition display" as described in Section 5. The two
red LEDs beside the sensor, also, turn on and FMX-004 is ready for
static charge measurement.--7

Five minutes after the power is turned on, FMX-004 will turn itself off③automatically. This is called "Auto power off function". In this case, a
combination of two beeps (0.15 second on and 0.1 second off) sounds
five times at one second interval to inform that FMX-004 will be turned
off soon.
When the power is on, if POWER button is pressed, FMX-004 turns off④and all indications disappear.
CAUTION
FMX-004 can be activated by pressing POWER button just once・lightly. There is no need to press it repeatedly. Frequent unnecessary
on/off operation or pressing by a nail may affect the life of switches
and the cover sheet.
In standard mode, the measurement cannot be done for more than five・minutes when "Auto power off function" is operative. For more than
five minutes measurement, select continuous measurement mode
when power is turned on as described in the next section.
5.2.2 Standard mode for ion balance measurement
FMX-004 can be used easily to measure ion balance voltage (offset voltage)
for many kind of ionizers using a ion balance plate provided.
5.2.2.1 Ion balance plate installation
During static charge measurement, the ion balance plate is attached to①the bottom end (opposite to that with the sensor) normally. For ion
balance measurement it should be removed and attached to the top end
having the sensor.
Press rear side release buttons from both side and draw out the ion②balance plate.
Insert the plate into the sensor side slots until it clicks into place and③stops as shown in the photograph below.
The plate should enter smoothly. It should not move when secured in④place properly. Forcible insertion could result in damage to the unit.
In order to remove the plate after ion balance measurement, press⑤sensor side release buttons from both sides and draw it out. The plate
can be kept attached to either end of FMX-004 when not in use.

CAUTION
Make certain that the surface of a white plastic plate under the ion・balance plate is clean before attaching it to FMX-004 for ion balance
measurement.
The ion balance plate should be stored or used in a place having less・than 60 %RH.
5.2.2.2 Grounding connection
FMX-004 can be used to measure low voltages up to ±300 V in the ion
balance mode. It is important to connect it to ground using the grounding
lead supplied, especially for ion balance measurement.
CAUTION
The plastic case of FMX-004 is made of conductive resin. The
grounding terminal provides the reference potential for the electrical
circuit. This terminal should be grounded for proper measurement. The
accuracy is not guaranteed for measurement with an ungrounded
FMX-004.
5.2.2.3 Ion balance measurement
Initially, ground the plate to remove any static charge. Press the center①of red circle button switch marked [POWER] once. A single beep (0.25
second) sounds to inform that FMX-004 is into standard mode.
Press the center of blue circle button switch marked [MODE] once.②LCD display shows "IB" along with digital numerical value, polarity
sign, unit of measurement "V", bar graph scale and battery condition.
FMX-004 is, now, ready for ion balance measurement. The two red
LEDs, located beside the sensor, do not light up. Please confirm state of
the battery from "Battery condition display" as described in Section 4.
Five minutes after the power is turned on, FMX-004 will turn itself off③automatically. This is called "Auto power off function". In this case, a
combination of two beeps (0.15 second on and 0.1 second off) sounds
five times at one second interval to inform that FMX-004 will be turned
off soon.
Press [POWER] button again to turn off FMX-004. All indications④disappear.
CAUTION
FMX-004 can be activated by pressing [POWER] button just once・lightly. There is no need to press it repeatedly. Frequent unnecessary
on/off operation or pressing by a nail may affect the life of switches
and the cover sheet.
