Safety Considerations

Caution note for the WME pins – The Pin Moisture Calibration of unit – The accuracy specifications of Calibration of unit – The accuracy specifications of the product are valid for one year from the date of calibration. Periodic calibration checking, as outlined in section 4, is advised.
Calibration of unit – The accuracy specifications of the product are valid for one year from the date of calibration. Periodic calibration checking, as outlined in section 4, is advised.
Only operate the measuring instrument properly, for its intended purpose and within the parameters specified in the technical data. Readings from moisture meters are not definitive but are used to help a professional make informed judgement to the material’s moisture condition. Conductive material such as salts, carbon and metal can give false positive readings.

Pin (WME) Mode Operation

The Protimeter TimberMaster is a conductivity moisture meter designed for use in wood. Moisture measurements can be taken using the integral pin electrodes. When used with the temperature probe, the moisture measurements are automatically corrected with respect to temperature. This feature is particularly relevant for users testing wood that is significantly above or below 20°C (68°F).
TimberMaster is switched on by pressing and holding it for a few seconds.
To switch OFF, press and hold for 3 seconds.
Unit turns off automatically after few minutes (can be set) when no key press is detected.

Using the Protimeter TimberMaster without the

Temperature Probe
The TimberMaster is calibrated for wood at 20°C (68°F).
In general, the effect of temperature on the moisture measurement calibration can be approximately compensated as follows:
For every 5°C above 20°C, subtract 0.5%mc from the value displayed.
For every 5°C below 20°C, add 0.5%mc from the value displayed.

Examples:

Wood temp: 20°C,
Moisture value: 15.5%.
Temp correction: 0
moisture content: 15.5%
Wood temp: 25°C,
Moisture value: 15.5%.
Temp correction: -0.5
moisture content: 15%
Wood temp: 15°C,
Moisture value: 15.5%
Temp correction: +0.5
moisture content: 16%
Wood temp: 30°C,
Moisture value: 15.5%.
Temp correction: -1
moisture content: 14.5%
Wood temp: 10°C,
Moisture value: 15.5%.
Temp correction: +1
moisture content: 16.5%

Reading with Integral Electrode Pins
Remove the cap to expose the needle electrodes and switch the instrument ON by pressing . Select the appropriate wood calibration scale (A, B, C, D, E, F, G, H or J) by referring to the enclosed Protimeter wood calibration tables and pressing . Push the pins in to the surface of the wood and observe the reading.

Reading with Moisture Probe or Hammer Electrode
Connect the moisture probe or (optional) hammer electrode to the 3.5mm socket at the right hand side of the TimberMaster, and switch ON by pressing . Select the appropriate wood calibration scale (A, B, C, D, E, F, G, H or J) by referring to the enclosed Protimeter wood calibration tables and pressing . Drive the moisture probe pins or hammer electrode needles in to the wood and observe the reading.

Using the Protimeter TimberMaster with the Temperature Probe

If the timber being measured is significantly above or below 20°C (68°F), the TimberMaster should be used in conjunction with the Temperature Probe. When this probe is connected the TimberMaster, it automatically corrects the measured moisture value with respect to temperature.

Automatically Temperature Corrected (ATC) Readings

Switch the TimberMaster ON and select the appropriate wood calibration scale as detailed in section 3.1 or 3.2. Using either a hammer electrode, or a hammer and nail of nominal 2mm diameter, make a hole in the wood to be tested. Remove the hammer electrode or nail, and push the temperature probe into the hole until the tip is at the required depth. Connect the temperature probe to the TimberMaster via the 2.5mm socket. To obtain the ATC moisture value, take moisture readings as detailed in sections 3.1 or 3.2 while the temperature probe is positioned in the wood and connected to
the TimberMaster. If the temperature of the wood is assumed to be equal to the ambient air temperature, ATC moisture values can be obtained by holding the connected temperature probe in air. Switch between temperature and moisture displays by pressing .

Calibration Check

The calibration of the TimberMaster is checked by holding the electrode needles across the exposed wires of the “calcheck” device (supplied) or across the terminals of the protimeter check box (optional accessory). When checking the calibration, the A scale should be selected and the temperature probe must be disconnected. Correctly calibrated TimberMaster will register a (%MC) value in the range of 18.0 ± 1%.

Care and Maintenance

When the TimberMaster is not in use, keep it in its pouch together with its accessories. Store the kit in a stable, dust-free environment out of direct sunlight. Remove the battery from the instrument if it is to be stored for periods of more than four weeks, or when the low battery power symbol appears on the display. Check the condition of accessories used with the TimberMaster instrument on a regular basis and replace them if they become worn or damaged.

Reference Mode

Measure the material until the meter’s reading is stable then press for 2 seconds. This will store the reading until the mode changes or the meter turns off. Now all readings taken after will be displayed as normal, but below you will see a second reading that shows you if the material is measured above or below the original reading. Reference mode can be useful when trying to establish what materials are above or below a point of reference or dry standard. See page 6 for further information.
