OPERATING INSTRUCTIONS

ON /OFF

1. Press the button to turn the device ON, press and hold the button for about 3 seconds to turn the device OFF.

Temperature measurement

The measurement of the temperature performing continuously, and the display shows the present environment temperature directly.
Temperature measurement performed by Celsius scale - "°C" or Fahrenheit scale - "°F".
Press button to switch between °C and °F.

Moisture measurement

1. Accuracy check:
   Before taking the first measurement check device's accuracy using the Test Aid.
   
   NOTE: The moisture meter maintains its declared accuracy of ± 2% inside of the operating temperature range 0 - 40°C. Outside of this range the accuracy of the moisture measurement degrades
   The Test Aid placed inside the protective cup and there are two measurement holes to use it:
   Switch to "WOOD" measurement mode and choose A calibration scale (see chapters b and c).
   Insert the measuring pins into the measurement holes and read the measured value. If the measured value on the display is between 16.6% to 20.6% - the meter is calibrated and ready for use.
2. Selecting desired Measurement Mode:
   There are two measurement modes available:
   • Timber moisture measurement - "WOOD"
   • Building material moisture measurement - "BLDG"

Press the button to select the desired measurement mode.

3. Selecting Calibration Scale (For Timber only):
   Timber moisture measurement performed by one of 8 calibration scales (A, B, C, D, E, F, G, H) for different kinds of wood materials. Refer to the Calibration Table for the scale that suits the wood type, and switch to the correspondent calibration scale by pressing the button.
   Chosen scale indicated at the bottom of the LCD screen.
4. Performing moisture measurement:
   Press hard both pins into the wood or material to be measured, read the value on the display. In addition to measured value on the LCD screen, the Red, Yellow, or Green LED lights will indicate the level of moisture in material:
   Timber:
   Green: Low moisture (< 12%)
   Yellow: Mid moisture (12% - 15.9%)
   Red: High moisture (16%-60%)
   Building material:
   Green: Low moisture (< 17%)
   Yellow: Mid moisture (17% - 19.9%)
   Red: High moisture (20%-33%)

Hold the measured value

Press the button to hold the measured value, "HOLD" icon will appear on the screen. Return to the regular measuring mode by pressing the or or .

Automatic Power-Off

If you will not operate the tool or the reading will not change for about 3 minutes, the instrument will be turned off automatically.

Low battery indicator

When the icon appears on LCD, it indicates that the charge of the batteries is low, and they should be replaced.

MAINTENANCE

The moisture meter has been designed to be a low maintenance tool. However, in order to maintain its performance, you must always follow these simple rules:

• Avoid exposing the tool to shock, continuous vibration or extreme hot or cold temperatures.
• Always attach the protective cap when not in use.
• Always keep the tool clean of dust and liquids.
• Check the battery regularly to avoid deterioration.
• Always remove the battery when storing the tool.
• Do not attempt to change any part of the unit.
• Do not disassemble the tool. This will void the warranty.
• Store the tool in a dry place.
• After measurement, clean the probes and the case using a clean cloth.
