MF-100 MOISTURE METER
Item No. 2633257
1. 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.
Read the operating instructions carefully and store them in a safe place. Make this product
available to third parties only together with the operating instructions.

4. SAFETY INSTRUCTIONS
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on
proper handling in this manual, we assume no liability for any resulting per-
sonal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
Personal safety
• The product is not a toy and should be kept out of reach of children!
Product safety
• Condensation may form in the device when transported from a cold to warm
environment. This may result in false measurement. Allow the device to get
acclimated to the new environment before operation.
• The product must not be subjected to heavy mechanical stress.
• The product must not be exposed it to extreme temperatures, direct sunlight,
intense vibration, or dampness.
• If there is reason to believe that safe operation is no longer possible, the device
is to be put out of operation and secured against unintended operation. Safe
operation is no longer possible if the device:
- shows visible damages,
- no longer works,
- was stored under unfavourable conditions for a long period of time or
- was subject to considerable transport stress
Battery safety
• Correct polarity must be observed while inserting the batteries.
• Batteries should be removed from the device if it is not used for a long period
of time to avoid damage through leaking. Leaking or damaged batteries might
cause acid burns when in contact with skin, therefore use suitable protective
gloves to handle corrupted batteries.
• Batteries must be kept out of reach of children. Do not leave the battery lying
around, as there is risk, that children or pets swallow it.
• All the batteries should be replaced at the same time. Mixing old and new
batteries in the device can lead to battery leakage and device damage.
• Batteries must not be dismantled, short-circuited or thrown into fire. Never
recharge non-rechargeable batteries. There is a risk of explosion!
Miscellaneous
• Users are responsible for the measurement results from this device. We do not
guarantee not accept liability for the measurements. Under no circumstances
will we accept the liability for damages caused by the application of the
measurement results.
• Repair works must only be carried out by a specialist/ specialist workshop.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.

6. INSERTING BATTERIES
three AAA batteries.
This moisture meter is powered by
1. Using a screwdriver, remove the battery compartment cover at the back of the meter.
2. Insert three AAA batteries, while observing the correct polarity.
3. Replace the battery compartment cover.
4. Replace batteries when the low battery indicator (9) illuminates on the LCD panel.
7. 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.
