Simco FMX-003 Instructions Manual page 6

Five minutes after the power is turned on, FMX-003 will turn itself off automatically.
③
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-003 will be turned off soon.
When the power is on, if POWER button is pressed, FMX-003 turns off and all
④
indications disappear.
CAUTION
FMX-003 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.
6.2.2 Continuous mode for static charge (voltage) measurement
Keep POWER button pressed for three seconds after turning the sensor side toward an
①
uncharged area. The number of red bars in the upper right side bar graph on the display
increases by one at one second interval. When three red bars appear, release POWER
button. Three beeps (0.15 second on and 0.1 second off) inform that FMX-003 is into
continuous measurement mode. This is called "Cancellation of the Auto power off
function". If POWER button is pressed for five seconds, a white LED at the lower side
turns on. This assists in reading the display in low room light level. This LED can also
be turned on by pressing POWER button more than one second and less than three
seconds. The LED does not turn on if pressing time is less than one second or more
than three seconds and less than five seconds. (See also page 20, section 8.4.)
In continuous measurement mode, LCD display shows digital numerical value, polarity
②
sign, unit of measurement "kV", bar graph scale, battery condition and "A.OFF". Please
confirm the state of the battery. The two red LEDs for assisting in working distance
adjustment should be turned on. FMX-003 is now ready for continuous static charge
measurement.

One minute after power is turned on, the red LED will be turned off automatically in
③
order to reduce the consumption of the battery. To turn the LEDs on again either press
HOLD button twice or ZERO button once. Once turned on, LEDs remain on for one
minute. (See page 20, section 8.3.)
Press POWER button once again to turn off the unit after measurement. All indications
④
disappear.
CAUTION
FMX-003 cannot be turned off without pressing POWER button in continuous
・
measurement mode. Confirm that power is turned off by observing the disappearance of
all indicators. If power is not turned off, the battery will be drained completely.
FMX-003 cannot return to this mode automatically, even if it is turned on again after
・
turning off in continuous mode. For going into continuous mode, the operation described
in 6.2.2 is should be carried out when power is turned on.
①
6.3 Zero adjustment by "Digital zero function"
A gray button switch marked "ZERO" on the front panel can be used to adjust the reading to
zero if the fieldmeter reading is not [0.00]. To make FMX-003 read [0.00] in this condition,
press the button once turning the sensor toward an uncharged area.
CAUTION
・ The digital zero function cannot be used for zero adjustment, if the reading of FMX-003
exceeds [±0.30] approximately. Also, when in hold mode, the function is inoperative.
・ If the reading is more than [±0.30] in a measurement, the digital zero function is
inoperative. However, if the reading is less than [±0.30], the real zero point would be
shifted by this function when ZERO button is pressed.
6.4 Measurement
FMX-003 has two red LEDs on the sensor side of the unit to help position the unit at the
right distance from a charged object. The measuring distance is 25 mm. With the sensor and
LEDs pointing towards the charged object, slowly bring FMX-003 close from far till two light
beams converge into a concentric circle.
