Introduction This manual describes how the GXA-25 External Fanless Ionizer (static eliminator) works and how to get the most out of it in terms of performance. Read this manual thoroughly before using the ionizer and keep it at hand for future reference. 1. Features □ The fanless ionizer (static eliminator) can eliminate static electricity from the weighing sample before weighing, reducing errors.
1.1. Part Names External input connector Connector for the ionizer IR (touchless) switch Connector for the option board Electrodes Connector for the external IR switch LED (Not to be used) Ionizer (rear side) Ionizer (front side) Option board Double-sided tape (To secure the ionizer) Electrodes Connection cable (60 cm) Stand 1.2. Installing the Ionizer Caution Disconnect the AC adapter before installing the ionizer to the balance. 1.
5. Place the ionizer on the stand and set it up on the side of the balance. (Secure the ionizer to the stand using the double-sided tape if necessary) Double-sided tape Stand 1.3. Using the Ionizer Note: Keep the weighing sample away from the electrodes while neutralizing. Placing the sample too close to the electrodes may cause the sample to become charged. Remove any obstacle between the electrodes and the weighing sample. The electrodes must not be touched with tweezers, etc., while neutralizing. 1.
2. Bring 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.
・ 1.4. Controlling the Ionizer Externally By using the foot switch (AX-SW137-PRINT or AX-SW137-REZERO), PRINT or RE-ZERO or the neutralization function for the ionizer can be operated. □ Connect the foot switch to the external input connector.
2. Function Settings of the Balance The function table stores parameters that specify how to operate the balance, and it is used to monitor or update the parameters. In the function settings, specify the GXA-25 operations. The parameters are stored in memory even if the AC adapter is removed and are retained until updated. The function table menu consists of two layers as shown in the diagram below. The first layer is the “Class” and the second layer is the “Item”. Each item stores a "parameter".
2.2. Function Table Note: Functions available differ by the balance model. Class ba5fnc Environment display CladjJ Clock adjustment Cp fnc Comparator Item Description Parameter Comparator value Cp beepEEP Comparator buzzer dout Data output 5if Serial interface U5b USB interface Refer to the balance instruction manual.
3. Maintenance of the Electrode Unit When using the ionizer for a long time, dust and stains may stick to the electrodes. Clean them periodically to maintain performance. 1 2 When needles of the electrodes are worn down and neutralization ability is not restored after cleaning them, replace both electrode units with new ones. The standard life of an electrode unit is approximately Cleaning Electrode needle 10,000 hours.
5. Options Electrode Unit AX-BM-NEEDLESET (4 pieces) □ Replacement electrode units □ Replace both units with new ones at the same time. □ Refer to "3. Maintenance of the Electrode Unit " for the replacement method. Foot switch with a plug (PRINT) □ AX-SW137-PRINT Controls the balance PRINT operation and the ionizer operations. Foot switch with a plug (REZERO) □ AX-SW137-REZERO Controls the balance RE-ZERO operation and the ionizer operations.
