Introduction
This manual describes outline of the ionizer (AX
-
ION

25)
and how to use it correctly. Please thoroughly read this
manual before using the AX

Features
This ionizer eliminate static electricity on the weighing sample by
generating bipolar ions from 4 electrode needles.
The ionizer can eliminate static electricity on a charged
weighing sample without breeze. A weighing error can be
reduced.
AC adaptor is needless because power of the ionizer is
supplied from main unit of the balance.
This ionizer can be controlled by using built-in IR sensor,
option IR switch (AX
-
IR
-
SWITCH).
Electrode unit is removable. A unit can be cleaned and
replaced.
Static electricity
In general, nonconductors such as powder, filter,
medicine wrapping paper, plastic etc. easily become
electrostatically charged when the ambient humidity is
less than 45 %RH. The static electricity may cause
weighing error of approximately few mg at weighing.
This ionizer can perform static elimination effectively.
3.
Cautions before Use
Read the following cautions for safety use of the ionizer.
Operate the ionizer gently because of precision instrument.
Do not install the following place.
Place getting water, vibration, shock, direct sunshine. Dusty place, air
including salt or corrosive gas, a place in flammable gas.
Do not turn on power of the ionizer until the installation is finished. The
switch to turn off is not equipped in the ionizer.

Connecting to the balance
Caution
Disconnect the AC adapter before
installing the ionizer to the balance.
1. Connect the ionizer to the balance using
connection cable.
2. Connecting the AC adapter of the
balance, the power lamp lights up.
The ionizer supports only BA series as of
May 2021. Refer the following homepage

Static elimination
1. Put the weighing sample into the effective range shown in the figure 1.
2. Responding the IR sensor (touchless infrared proximity sensor) on the front
panel, option IR switch, the ION lamp lights up and static elimination starts.
3. Perform static elimination referring to the figure 1. Static elimination process
stops automatically in 3 seconds and ION lamp turns off for factory setting.
Referring to "
7. Optimizing the Ionizer
", optimize static elimination method
and discharging time if the distance between electrode needles and
weighing sample is 10 cm or father.

Connecting Options
Caution
Remove power supply cable when connecting peripherals to
the ionizer.
Static elimination process can be controlled by using
option IR switch instead of the built-in IR sensor. The
ionizer can not send PRINT and RE-ZERO command
to the balance by using option IR switch

7. Optimizing the Ionizer
Static elimination method can be optimized by using switches on the
rear. Refer to the following table for functions of switches. Change the
settings of the switch 1 and switch 2 eliminating static electricity
outside the effective range shown as in the figure 1.

When switch 1 is selected "Timer mode", static elimination is
performed for "Discharging time" set by switch 2.
#2
Once static elimination has started, it continues until built-in IR
sensor or option IR switch responds again when switch 1 is selected
"Manual mode". "Manual mode" does not stop static
elimination automatically.

The setting of the switch 2 is effective when switch 1 is
selected "Timer mode".

Buzzer sounds at power on and responding the built-in
IR sensor or option IR switch.

Maintenance
Caution
Do not touch the discharge electrode unit to avoid
electric shock during neutralization.
When the ionizer is used continuously, discharge
electrode needle and around may get dirty and
neutralization performance may become weak. Clean the
electrode needle periodically using cotton swabs to
maintain performance.
When the electrode needle wears out and static elimination
performance does not refresh by cleaning, replace all of
discharge electrode units to new ones of option. Life time of
discharge electrode unit is approximately 10000 hours.
Procedure of replacement
1. Remove the connection cable to turn off the ionizer.
2. Rotate a discharge electrode unit to 45 degree
counterclockwise. Remove it.
3. Insert new units and rotate them to 45 degree clockwise.
