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.
Press POWER button again to tu rn off FMX-003. All indications disappear.④
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 fu nction" is operative. For more than five minutes measurement, select
continuous measurement mode when power is turned on as described in the next section.
7.3.2 Continuous mode for ion balance measurement
Ground the ion balance plate to remove any static charge. Keep POWER button pressed①
for three seconds. The number of red bars in the upper right side bar graph on the
display increases by one at each 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 t han 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.)
Press IB button once. LCD display shows digital numerical value, polarity sign, unit of②
measurement "V", bar graph scale, battery condition, "IB" and "A.OFF". FMX-003 is,
now, ready for continuous ion balance measurement. Focussing red LEDs do not light
up. Please confirm the state of the battery.

Press POWER button once again to turn off the unit after measurement. All indications③
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 ion balance measurement
mode, the operation described in 7.3.2 and should be carried out when power is①②
turned on.
7.4 Zero adjustment b y "Digital zero function"
Thegraybuttonswitchmarked"ZERO"onthefront panel can be used to adjust the reading
to zero if required. Press the button once after residual static charge is removed by grounding
the stainless steel plate.
CAUTION
The ion balance plate is not grounded by pressing ZERO button. It should be grounded to・
remove its static charge by making contact with grounded conductors.
The digital zero function cannot be used for zero adjustment, if the reading of FMX-003・
exceeds [±50] approximately in the i on balance measurement mode. And also, when in
hold mode, the function is inoperative.
If the reading is more than [±50], the digital zero function is inoperative. However, if the・
reading is less than [±50], the real zero point would be shifted by this function when
ZERO button is pressed.
