Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a precision management method for a moisture measuring device, capable of always simply confirming whether the precision is good or not usually so as to simplify and facilitate precision management. SOLUTION: In this precision management method for the moisture measuring device, moisture content of material to be measured such as freshly mixed concrete, mortar, and sand is obtained by a means for measuring the electrostatic capacity of the material to be measured. The precision of the moisture measuring device is confirmed by measuring the electrostatic capacity of the material having known electrostatic capacity built in a calibrating reference body 140, and comparing the measured value with a reference value.
