When I acquire DI input with the BFD32 and perform statistical computation (averaging) on the Viewer software, I get computation errors 0 and 1.

The Viewer cannot determine the numbers after the decimal with statistical computation on DI input. Data acquired and results computed by the BFD32 are affected by the decimal of the specified measurement range. For DI (contact input), a 4.2 µA current (using a power supply for burnout) flows and the open/close determination is made. It is set so that less than 10 KΩ is 1 (close), and 10 KΩ or over is 0 (open). For the range, the number of places after the decimal is fixed at 0. Therefore, if the Viewer calculates statistics on DI input data acquired by the BFD32, the range's number of decimal places is 0, and the computed value's decimal places are rounded to either 0 or 1.
