Auto Power OFF

The meter will automatically power OFF if the reading stays 0% for 3 minutes. If the meter detects

readings, other than 0%, it will not automatically power OFF.

Display (Hold) Lock

Short press the Display Lock button to freeze the displayed reading. The icon is visible on

the display when Display Lock is active. Press again to return to the normal operating mode.

Beeper ON/OFF

The beeper defaults to ON. To switch the beeper OFF, long press the Display Lock/Audible Beeper

button . When the beeper is active, the audio display icon will be visible.

Pinless Moisture Measurements

1. Short press the Material Select button ( ) to toggle the Wood and Building Material

modes of operation. The displayed icon indicates the selected mode.

2. To take a measurement, hold the meter and position the sensor so that it is directly touching

the surface under test (at any angle). The meter can sense moisture to a depth of 10.2cm (4”).

NOTE: The position of your hand can affect the reading. Do not move or reposition the hand

that holds the meter while taking measurements or when powering the unit.

3. Observe the displayed relative readings, view the displayed moisture droplet icon(s)

(more

drops indicate higher moisture levels), and listen for the audible beeping (faster beeping

indicates higher moisture; there are eight intensity levels). As discussed in the Measurement

Considerations section, the displayed reading is an average of the moisture measured over the

tested surface area to the maximum penetration depth.

4. Long press the power button to power OFF the meter.
