What is modification used for?

DRAMINSKI TwistGrain gives possibility of modifying calibration curves. Moisture meter users can calibrate the device on their own, i.e. modify preset moisture curves for each species, which curves have been created based on comparative studies with the use of an oven-drying method.

Calibration consists in modifying (correcting) meter readings by increasing or decreasing the value of readings for a given species by the same amount within the entire measurement range. Modification is made, if the user finds that for a given species a device tends to overestimate or underestimate the results by a similar value within the entire moisture range.
