Page 9: Device Set-Up And Adjustment For Measurement
4. DEVICE SET-UP AND ADJUSTMENT FOR MEASUREMENT Certain parameters which depend on measured sample and measurement conditions must be adjusted before measurement. This is crucial because measured moisture content greatly depends on parameter settings. 4.1 WOOD TYPE (or CONCRETE TYPE) parameter setting Information regarding type of wood (or concrete) is defined by the value of parameter TYPE , which represent the... -
Page 10: Wood Temperature (Or Concrete Temperature) Parameter Setting
WOOD TEMPERATURE (or CONCRETE TEMPERATURE) parameter setting Second data needed for correct wood moisture content measurement is wood temperature (most commonly wood temperature is equal to surrounding air temperature, so this data can also be used as relevant data for measurement). Temperature is entered in Therefore, it is necessary to measure wood or air temperature using appropriate thermometer, and enter that value as a TEMPERATURE... -

- Connect the probes and instrument using measurement cable: connect BNC connector on one side of cable to RVD-904, and free endings on the other side of cable to probes hammered in the wooden sample. Measurement circle is formed this way and system is ready for measurement;... -
Page 12: General Notes Regarding Wood Mc Measurement
5.1 General notes regarding wood MC measurement universal portable moisture meter RVD-904 operation principle is based on electric resistance measurement method. Electric resistance of the wood depends on wood moisture content, with almost linear dependancy in range 4% to 30% MC. For obtaining most accurate data, it is best to perform measurement in several points. -
