Material ModeTypical Inspection ApplicationWoodTimber panels, suitable wooden surfacesBrickBrick walls and compatible masonryConcreteConcrete walls and floorsStoneCompatible stone surfaces
Important: The material modes use different instrument scales.
A displayed reading from wood mode should not automatically be compared with a reading from concrete mode.
Step 6 - Perform Zero Adjustment
Follow the GT611 manual to perform the recommended zero adjustment.
The instrument should be positioned as specified by the manufacturer during this process.
Avoid placing the sensor against the test material during zero adjustment unless the manual specifically instructs otherwise.
Proper zero adjustment helps improve measurement consistency.
Step 7 - Select a Reference Area
Before measuring a suspected damp area, identify an apparently unaffected location made from similar material.
For example, when inspecting a brick wall, select a nearby brick wall section with similar plaster and surface finish.
Take several readings and record them.
These values provide a reference for comparison.
An apparently dry reference area is not necessarily completely moisture-free.
Step 8 - Position the Sensor Correctly
Place the GT611 ball-shaped sensing head against the accessible surface according to the manufacturer's instructions.
Maintain consistent sensor contact and positioning.
Avoid excessive force that could damage the instrument or delicate surface finishes.
Step 9 - Take Multiple Measurements
Measure several locations rather than relying on a single reading.
For example, when checking a suspected damp wall:
Measure an apparently unaffected reference area.
Measure the centre of the suspicious patch.
Measure the area above the patch.
Measure the area below the patch.
Measure nearby sections of similar material.
Record the displayed readings and measurement locations.
Step 10 - Compare the Results
Compare readings from similar materials and surface conditions.
An area showing a noticeably different response may require further investigation.
However, a high reading does not automatically confirm water leakage.
Differences in material composition, concealed metal, or construction layers may affect the result.
Step 11 - Use the Data Hold Function
Where useful, activate the GT611 data hold function according to the supplied manual.
This allows the displayed reading to be observed or recorded.
Step 12 - Record the Inspection Findings
For professional inspection work, document:
Inspection date
Building location
Material type
Instrument model
Selected material mode
Reference readings
Suspected damp-area readings
Visible damage
Relevant environmental conditions
Recommended follow-up actions
Photographs and simple inspection diagrams can help identify the same locations during future checks.
Step 13 - Switch Off and Store the Instrument
After completing the inspection:
Switch off the instrument.
Clean the sensing head using a suitable dry, soft cloth.
Store the instrument in a clean, dry location.
Avoid exposing it to excessive heat, moisture, or physical impact.
Remove the batteries for extended storage where appropriate.
Follow the manufacturer's maintenance instructions.
