2. Bring the your hand close to the IR (touchless) switch located at the center of the ionizer.
When the IR switch responds to the hand, the ION mark on the balance’s display and the ionizer’s
LED light up and neutralization starts. When an interval (three seconds at factory settings) set in
the balance’s function settings beforehand has passed, neutralization stops automatically. While
neutralizing, make sure that the weighing sample is lifted up approx. 2 cm or more and is
neutralized until the ION mark at the balance’s display and the LED at the ionizer turn off.
Lift up the weighing
sample approx.
2 cm or more.
□
When a balance with a minimum display of 0.001g is used, the balance operates using a
minimum display of 0.01g while the ionizer is operated, and then the balance automatically
returns to the previous weighing mode when operations for the ionizer are completed..
□ While neutralizing, make sure that the weighing sample is lifted up and is neutralized until the
ION mark at the balance’s display and the LED at the ionizer turn off. Failure to do so may
result in the weighing sample not being sufficiently neutralized and cause weighing errors.
□
The neutralization interval can be changed using the balance’s function settings. (Refer to “2.
Function Settings of the Balance”)
(Reference) at 4kV electrical charge
Distance 10 cm 20 cm 30 cm
Neutralization interval 1 second 3 seconds 10 seconds
□ If the IR switch is kept at ON after neutralizing, the ionizer indicates a warning by blinking the
LED.
□ When the neutralization interval is set to “manual”, the ionizer can only be controlled externally.
The “manual” neutralization interval is up to 10 minutes.
