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 f anless DC ionizer (stati c eliminator) can eliminate static electricity from the weighing sample
before the measurement, reduc ing 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 re pl aced.
□ 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 ch arged with static electricity. The influence of the st atic electricity may cause a
weighing error of several milligrams. The ionizer effectively neutral iz es the electrical charge.

2. Peel off the connector that is affixed to th e panel with double-sided
tape and insert it into the socket of the option board.
3. Attach the option board to the balance.
Secure with the two screws remov ed in st ep 1.
4. Connect using the connection cable (60 cm) between the I/F
board and Ionizer.
