Setup
Installazzjoni tal-batterija
- Locate the battery compartment on the back of the MO55 meter.
- Iftaħ l-għatu tal-kompartiment tal-batterija.
- Daħħal batterija waħda ta' 9V, waqt li tiżgura l-polarità korretta (+/-).
- Agħlaq l-għatu tal-kompartiment tal-batterija sew.
Qawwa Inizjali Mixgħula
Agħfas il-buttuna tal-enerġija (⑂) to turn on the device. The display will illuminate, and the meter will be ready for use.
Istruzzjonijiet Operattivi
Selecting Measurement Mode (Pin vs. Pinless)
The MO55 offers two measurement modes:
- Pin Mode: For direct contact measurements using the integrated pins. Ideal for wood and building materials where penetration is acceptable.
- Pinless Mode: For non-invasive measurements, suitable for detecting moisture behind surfaces like tiles or walls without causing damage.
To switch between modes, refer to the mode selection button on your device. The display will indicate the active mode.
Taking Pin Measurements
- Remove the protective cap from the pins.
- Gently push the pins into the material you wish to measure. Ensure both pins make firm contact.
- Read the moisture content percentage murija fuq l-iskrin.
- The audible alert will beep faster as moisture levels increase.
- Press the Data Hold button to freeze the reading if needed.

Figure 6: A hand holding the Extech MO55, with its pins inserted into an OSB (Oriented Strand Board) panel, likely checking for moisture. The display shows a reading of 28.5%.
Taking Pinless Measurements
- Ensure the meter is in pinless mode.
- Place the back of the meter flat against the surface of the material.
- Move the meter slowly across the surface to scan for moisture.
- Observe the moisture content percentage on the display. The meter can read up to 1 inch (25mm) deep.
- The audible alert will indicate increasing moisture levels.

Interpreting Moisture Readings
The MO55 provides visual moisture icons (water droplets) on the display to indicate low, medium, and high moisture levels. Consult the material-specific moisture content chart (often found on the back of the device or in the full user manual) for accurate interpretation of readings for different materials.
Manutenzjoni
Tindif
Wipe the meter with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the pins are clean and free of debris after each use.
Sostituzzjoni tal-batterija
When the battery indicator shows low power, replace the 9V battery as described in the "Setup" section. Remove the battery if the meter will not be used for an extended period to prevent leakage.
Ħażna
Store the MO55 in a cool, dry place, away from direct sunlight and extreme temperatures. Always replace the protective cap over the pins when not in use to prevent damage and injury.
