PROBE

The instrument is calibrated for wood at 20°C (68°F). In general, timber

that is hotter than 20°C will give higher readings and timber 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%

moisture content per 5°C may be added to the measured value.

Switch the instrument on and select the appropriate wood calibration

scale as detailed in sections 1. Using a hammer and nail of nominal 3 mm

diameter, make a hole in the wood to be tested. Remove the nail and

push the Temperature Probe into the hole until the tip is at the required

depth. Connect the Temperature Probe into the instrument via the "Temp"

socket. Then using this instrument to measure timber can obtain the

automatically temperature corrected (ATC) moisture value. If you need to

read current temperature of timber press "T" button, then LCD will display

the temperature. Press "T" button the LCD will display either °C or °F

temperature. Pressing "
