MEASURING MOISTURE LEVEL

To measure the moisture level of wood or a building material, first make sure
that its icon appears on the left side of the display. If it does not, press the
button briefly to toggle between wood and building materials. Next,
decide which sensor to use (the meter's pins or pad) after considering their pros
and cons presented in the introduction. Either 1) Gently press or push the pins at the
top of the meter on or into the material or 2) Press the split pad sensor on the back
against a flat area of the material, making sure that both sides of the pad touch the
surface being measured.
The MMH800 provides three indications of a material's measured moisture content:
1. A percentage reading on the upper display.
2. One, two or three droplet icons (
whether the reading is low, medium or high for the material. The moisture-level
range for each category is different for wood/paper and building materials; see the
Specifications section for the exact percentages.
3. If enabled (the factory default), the meter's repeating beeper will sound at one of
three rates (slow, medium or fast) corresponding to the measured moisture level
(low, medium or high). The audible changes make it very easy to pinpoint areas of
peak wetness.
To hold a measurement, press the

The meter's beeper is enabled by default. To disable the beeper, press the

button again for at least three seconds. Each time the meter is powered on, the unit
reverts to the default state: beeper enabled.
Some measurement tips:
1. To locate the source of a leak behind wood, plaster, drywall or a ceiling, make
measurements at different locations. The leak is where the meter displays the
highest reading.
2. Never use force to drive the test pins into a hard surface.
3. When measuring the moisture level of soil, surface readings will be lower than
readings with the test pins deep in the soil.
