I built a measuring device with which I can measure the insulation in MOhm. Up to a value of 10MOhm, the device is very precise, the only way to make it more and more inaccurate. from a measured value of 10, the measured value deviates more and more from the real value.
I set up a series of measurements with the deviation in percent.
|real value||measured value||Deviation in percent %|
Is it possible to correct the value with Node red so that I can not only measure exactly up to 10 but up to 200?
