FUNCTION BUTTONS

POWER ON/OFF BUTTON 4
Press the Power On/Off Button to turn the meter on or off. Press and hold the Power On/Off Button for 2 seconds to turn the meter off.
NOTE: To conserve battery life, the meter will automatically power off after 10 minutes of inactivity.

MODE BUTTON 3
Repeated presses of the MODE button will toggle through the available material types: Drywall, Masonry, Hardwood, and Softwood, in that order. Select the desired material prior to testing.
HOLD BUTTON 5
Press the HOLD button to lock the current reading. The reading will remain on the display until the HOLD button is pressed again, or until the meter automatically powers off.

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.

BAR GRAPH MOISTURE INDICATORS
MATERIAL	GREEN LEDs	YELLOW LEDs	RED LEDs
DRYWALL	0 to 40%	40 to 70%	70% +
MASONRY	0 to 36%	36 to 63%	63% +
HARDWOOD	0 to 14%	14 to 24.5%	24.5% +
SOFTWOOD	0 to 21%	21 to 39%	39% +

MAINTENANCE

BATTERY REPLACEMENT
When the Low Battery indicator is displayed on the LCD, the batteries must be replaced to avoid inaccurate measurements. the batteries must be replaced to avoid inaccurate measurements.

Loosen the screw to remove the battery door 7 .
Remove and recycle the exhausted 9V battery.
Install the new battery.
Replace the battery door and tighten the screw.

To avoid the risk of electric shock, do not operate the meter while the battery door is removed.
