摘要

A device and method for calibrating an apparatus to measure the moisture of a sample (e.g. wood) by measuring its impedance. The device contains an antenna and an adjustable impedance (resistor and capacitor).
The impedance of the calibrating device is set a reference value. Then the calibrating device is inserted into the moisture measurement apparatus and the difference between the measured value at the reference value is recorded. This is carried out for at least two reference values. Those at least two calibration points are used to calibrate the measurement apparatus.
