Conversion program using Scaling instruction (F282)
-
Appropriately interpolated data can be obtained from nonlinear data by creating the data table of digital
values after conversion and temperature and executing the scaling instruction (F282).

Do not connect anything with the 1/2 pin.
Voltage input value and digital conversion value
-
Use the following formula to convert the voltage input value and digital conversion value.
(Digital conversion value + 1)
Voltage input value (V) =
