Introduction
This manual describes how the GXA-25 External fanless ionizer (static eliminator) work and how to
get the most out of them in terms of performance. Read this manual thoroughly before using the
ionizer and keep it at hand for future reference.
１．
Features of the Option
□
A fanless DC ionizer (static eliminator) can eliminate static electricity from the weighing sample
before the measurement, reducing weighing error.
(Bipolar ions are generated by DC corona discharge and the target is irradiated by those to
neutralize it.)
□
Each electrode unit of the ionizer is designed to be removed, cleaned and replaced.
□
An IR (touchless) switch is attached to the ionizer, and neutralization can be started without
touching the ionizer.
□
Power is supplied from the balance to allow the ionizer to be operated without using an AC
adapter.
□
PRINT or RE-ZERO or the neutralization function for the ionizer can be operated by using the
accessory foot switch (AX-SW137-PRINT or AX-SW137-REZERO).
Static electricity
In general, when the ambient humidity is less than 45%RH, powders, paper, plastic, nonconductors,
etc., easily become charged with static electricity. The influence of the static electricity may cause a
weighing error of several milligrams. The ionizer effectively neutralizes the electrical charge.
