INTENDED USE

This non-invasive digital moisture meter is ideal for measuring moisture content in concrete, wood and other building materials. This helps to check if the surface is ready for  painting or covering. Large surface areas can also be quickly and effectively measured by using the alert function. The user can concentrate on the measured object without  having to constantly read the measurement values on the display. The device produces a beeping noise if the moisture level exceeds the threshold value. This device features a  wide measuring range, with a penetration depth of about 20 – 40 mm. It has min / max display and a low battery indicator.
The device is powered by three AAA batteries.  The product complies with the statutory national and European requirements. For safety and approval purposes, you must not rebuild and/or modify the product.

OPERATION

General information before measurement

1. The moisture level is an average value, which is influenced by the moisture at the exterior surface and the interior core of the material. If there is visible surface moisture  or water, wipe off any excess and let dry for a couple of minutes before measuring.
2. Other elements may also affect the reading. Before measurement, the measuring surface must be cleaned of any residual paint, dust, etc.
3. Hold the meter as far back as possible to avoid moisture influence from your hand.
4. The meter is not designed to measure metal or other materials which are strong conductors. If embedded metal (e.g. nails, screws, cables, pipes) is within the measuring  field of the sensor, the readings will increase significantly.
5. If the spherical head is placed at a wall corner, the reading may be higher as two or three surfaces are within measuring distance. To avoid interference, maintain a  minimum distance of 8 to 10 cm from other surfaces.
6. Place the spherical head on smooth surfaces. Rough surfaces will cause inaccurate readings.
7. The penetration depth of the device is 20 to 40 mm. Depending on the density of the material, reading of inner depth is not possible. If the material is less than 2 cm  thick, the moisture content value may not be as accurate due to influence from adjacent material.
8. The spherical head must be kept perpendicular to the surface being measured.
9. The density of the measured material is an important factor to the measured value. The measured value increases with density.
10. A main field of application for this device is for comparative measurements, comparing measured values against a reference value. The reference value is established by  measuring a similar or identical material at a clearly dry area. If the subsequent measurements are much higher than the reference value, it can be deduced that the areas  being measured are damp. This procedure is well suited for water damage assessment, to detect leaking locations and areas of high humidity.

Measuring the moisture content

1. Turn the measuring device on by using the ON/OFF button (5). The device automatically switches into HOLD (12) mode, i.e. no measurement is possible at this stage.
2. The measurement device has to be calibrated each time it is turned on. To calibrate it, hold the measuring device up in the air, so that it does not touch any objects. The  minimum distance to any other surface should be 8 to 10 cm. Press the MEAS button (7) to start the calibration.
3. During calibration, the LCD will show .
4. After completion of the calibration, the LCD (6) will display the current moisture reading (10). This value should be less than 0.5. If not, turn the measurement device  off and repeat the calibration.
5. Position the moisture sensor’s spherical head (1) at a right angle to the surface. The display will show the reading.
6. Move the measurement device to conduct measurements of larger surface areas. The LCD should thereby display the current reading as well as the max. moisture  reading (11) and min. moisture reading (16).
7. If required, press the MEAS button to freeze the readings on the display. The display will show HOLD, in addition to the last measured reading.
8. The readings are then displayed on the LCD for another 60 seconds, before the measurement device turns itself off.
9. Alternatively, in HOLD mode press the MEAS button to continue measuring.

Setting the alert function
The meter also display three non-numerical formats of measurement: DRY, RISK and WET.
When the moisture status is at RISK and WET, the meter emits beeping alert noises.
At RISK level, the meter will beep about once every second.
At WET level, the meter will beep about three times every second.
By default, a moisture reading of < 30 is indicated by DRY; 30 – 60, by RISK; above 60, by WET.
Different materials have different tolerance of moisture. For more information, refer to Technical
Data. To program your threshold range:

1. When the HOLD icon (12) is displayed, press SET to enter the alert mode.
2. The RISK icon will blink. Press UP (2) or DOWN (4) to adjust the lower threshold value for RISK. The value can be adjusted from 0 to 50. Press SET to confirm your choice.
3. The WET icon will blink. Press UP (2) or DOWN (4) to adjust the lower threshold value for WET. The value can be adjusted from 50 to 100. Press SET to confirm your  choice.
4. The LCD returns to the initial display.
5. The threshold value is permanently stored until it is changed next time.

Backlight
When the HOLD icon is displayed, press UP to switch the backlight on or off.

CARE

Clean the device as necessary with a soft damp cloth that is lint-free. Do not allow moisture to penetrate into the housing. Do not use sprays, solvents, cleaning agents that  contain alcohol or abrasives; instead use only clean water to moisten the cloth.
