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)
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.
