OPERATING INSTRUCTIONS
- Power on the meter 4 .
- Press the MODE button 3 until the desired material type appears on the display.
- Scan the material by pressing sensor 6 against the material to be tested. To ensure the best accuracy, press the back of the meter against a flat area of the material. The sensor measures up to 3/4″ (19 mm) thick. The display will show the percentage of moisture numerically A, and segments of the Bar Graph 2 will illuminate as a visual reference of the level of moisture present in the material per the chart below.
NOTE: “OL” will appear on the display if the moisture content detected
lies outside the meter’s measurement range.
NOTE: “ER” will appear on the display if the material type is not
supported by the meter.
