Top view

Read the following cautions for safety use of the ionizer.
Operate the ionizer gently because of precision instrument.

INSTRUCTION MANUAL

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.

Caution Do not touch the discharge electrode unit to avoid
electric shock during neutralization.

How to Use

Preparing the AC adapter

reduced.

Static electricity
In general, nonconductors such as powder, filter,
medicine wrapping paper, plastic etc. easily become
electrostatically charged when the ambient humidity isless than 45 %RH. The static electricity may cause
weighing error of approximately few mg at weighing.
This ionizer can perform static elimination effectively.

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 #2
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#3
process stops automatically in 3 seconds and ION lamp turns off forfactory setting. Referring to "7. Optimizing the Ionizer", optimize
static elimination method and discharging time if the distance between #4
electrode needles and weighing sample is 10 cm or father.

Optimizing the Ionizer

Switch 1
Static elimination method

Example of the Outlet

This ionizer can be controlled by using built-in IR sensor,
option IR switch (AX-IR-SWITCH).

1. Remove the AC adapter 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.

Features

When the electrode needle wears out and static
elimination performance does not refresh by cleaning,
replace all of discharge electrode units to new ones ofoption. Life time of discharge electrode unit isapproximately 10000 hours.

Option IR switch

Connecting Options

Static elimination process can be controlled by using
option IR switch instead of the built-in IR sensor. The
ionizer cannot send PRINT and RE-ZERO commandto the balance by using option IR switch.

Optimizing switch

When the ionizer is used continuously, discharge
electrode needle and around may get dirty andneutralization performance may become weak. Clean theelectrode needle periodically using cotton swabs tomaintain performance.

Procedure of replacement

Caution Remove power supply cable when connecting peripherals tothe ionizer.

Static elimination operation can becontrolled by moving hand over the"SENSOR".

When switch 1 is selected "Timer mode", static elimination is
performed for "Discharging time" set by switch 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 turning the power on or responding the built-in IR
sensor or option IR switch.
