    [Calibration sample] can be displayed in a form of numerical expression, graph, list and etc. The criterion calibration set in HB-300 is a numeric expression of correlation of moisture and electric resistance. It was obtained by measuring electric resistance of a timber with a 4needle probe and its actual moisture measured by the drying process.

    9-2. How to produce the calibration curve • Use the same probe that will be used to measure the sample later. Do not change the setting of "Constant" or "Fix" if using the standard probe. Using different probes or different ways of measurement such as angle of the probe and depth may affect accuracy. • While making a calibration, tr y to make the environment of measurement as equal as possible to the environment at the site where you will be using the instrument later. Especially difference of temperature will affect accuracy. • It is necessary to make multiple calibrations and register them respectively if seasonal temperature changes of the sample are expected.
