Depending on your measurements, connect the heavy duty moisture probe on the right hand side of this instrument and switch the instrument on by pressing the button. This instrument has eight calibration scales enabling the user to take accurate moisture measurements in 150 wood species. Select the appropriate wood calibration scale (A, B, C, E, F, G, H or J) by referring to the enclosed wood calibration table (see the manual for the calibration table for wood and common timber species) and by pressing the button. Push the needle pins or the heavy-duty moisture probe pins into the wood and observe the reading in the Moisture Meter’s LCD display. Measuring Without Temperature Probe By default, this Reed wood moisture meter is calibrated for wood at 20°C (68°F). If the timber is hotter than 20°C will give higher wood moisture readings and colder than 20°C will give lower readings. An approximate manual correction of 0.5% moisture content per 5°C may be subtracted from timber that is above 20°C. For timber that is below 20°C, a manual correction of 0.5. Automatically Temperature Corrected (ATC) Firstly, you need to made a 3mm diameter hole into the wood. In this hole, push the temperature probe until the tip is at the required depth. Now you can connect the temperature probe into the instrument via the temp socket. Using the instrument to measure timber you can obtain the automatically temperature corrected (ATC) moisture value. If you need to read the current temperature of the timber press the button, then the LCD will display the temperature. Press the button again and the LCD will display the other °C or °F temperature. Press the button and the LCD will display the moisture value again.
