4. Equipment and usage
This instrument is a conductivity moisture meter specifically designed for the timber
industry. The instrument has eight calibration scales, enabling the user to take accurate
moisture measurements in 150 wood species. Moisture measurements can be taken
using the integral pin electrodes, or using the heavy duty moisture probe. When used
with the temperature probe, the moisture measurements are automatically corrected
with respect to temperature. This instrument is switched on by pressing "
and switched off by pressing " " and holding for 3 seconds or more. The instrument
will switch off automatically after 5 minutes, the default automatically switch off time can
be setting range 1 to 9 minutes (see 5.5).
5. How to use device
5.1 Device description see page 13
5.2 Measuring Instruction
Remove the cap to expose the needle electrodes OR Connect the heavy
duty moisture probe socket on the right hand side of this instrument and
switch-on by pressing " ". Select the appropriate wood calibration scale
(A, B, C, E, F, G, H or J) by referring to the enclosed wood calibration table
and pressing " ". Push the needle pins or the heavy duty moisture probe pins into
the wood and observe the reading.
5.3 Using this instrument without the Temperature 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 rea-
dings. 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.
5.4 Automatically Temperature Corrected (ATC)
Switch the instrument on and select the appropriate wood calibration scale as
detailed in sections 5.2. 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 reading current temperature of timber press "T" button, then LCD will
display the temperature. Press "T" button the LCD will display the other °C or °F
temperature. Pressing " " button the LCD display moisture value again. (Tempe-
rature Range: -35°C ~ 80°C).
