The sensor measures up to 3/4" (19 mm) thick. The display will show the percentage of moisture numerically , and segments of the Bar Graph 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.

MAINTENANCE

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

1. Loosen screw to remove battery door .
2. Remove and recycle exhausted 9V battery.
