1. Features-----------------------------------------------------------------------------------------------------------------------------------------This software “Windows Communication Tools for data transmission with the GX-AE/GX-A/GF-A Filter”(hereinafter referred to as “WinCT-GXA-Filter”) can change the A&D electronic balance GX-AE/GX-A/GFA series filter settings on PC.
・The setting data can be read from the balance and changed all at once.
・The setting contents can be saved in CSV file format.
・The saved CSV file can be read and the setting contents can be written to the balance.
・The extended function (filter detailed setting) can be switched on and off.

Note・This software cannot be used unless the software version of the balance is 1.320 or later.
For instructions on how to confirm the software version of the balance, refer to the instruction manualof the balance.
・This software cannot be used for communication with the USB interface of a balance with software
version 1.320. Connect the balance to a PC with an RS-232C interface.
(Balances with software version 1.400 or later can also be connected with the USB interface.)・This software cannot be used when the password lock function of the balance is enabled. Also, it cannot
be used to switch the function from disabled to enabled state. Use the keys on the balance to set thepassword lock function.

These are items that can be changed in User Setting Mode.
If the weighing value is within a certain range (stable detection range)
and a certain time (stable detection time) has passed, it is judged to bestable. If it is judged to be stable, the display will show a circle indicating
the value is stable.
If it is judged to be unstable, that circle will disappear.
In this setting, set the stable detection range. If you want to judge
strictly until stable, set the numerical value to a smaller one.
For loose judgement, set the numerical value to a larger one.

5・6789[Averaging range]

Averaging begins when weight variation is within a designated range.
When filling very small amounts, if the averaging range is large, theweight will not deviate from the averaging range and the response canbe slow. You can reduce the averaging range to increase the response
speed. On the other hand, when the averaging range is small, themeasured weight can become unstable. In this case, you can increase
the averaging range.
Note: Averaging ranges are different depending on the digital filter
settings. This table shows reference values.
