Press CME4 fully aginst the surface of the concrete slab or screed. (Surface should be smooth and free of coatings/contaminants)
Readings are instant and dispayed on analog dial.
To freeze readings press the HOLD button once. In HOLD mode the upper LED will flash continuously. If CME4 is shut down in HOLD it will retain the stored reading when powered up next and remain in HOLD with the upper light flashing until the button is pressed again.
Automatic power timeout (10 mins) conserves battery life.
SCALES
Top Scale - Red - for use with Concrete Slabs & Sand/Cement screeds.
Equivalent reading to Moisture Content (MC%) or moisture by mass/weight as per the oven dry/gravimetric method.
Middle Scale - Yellow - for use on Gypsum Floor/Screeds.
Reference readings replicating measurements using concrete scale on concrete & sand/cement floors/screeds.
Bottom Scale - 0-100 - intended for use with materials other than concrete & screeds, such as stone & tiles etc.
This scale is for reference only and is not to be interpreted as moisture content or relative humidity.
Annual calibrations are recommended as best practice to ensure continued accuracy and reliability. Calibration Check Plates can be purchased for more regular checks. The Tramex Calibration Check Plate can be used to test the CME4 & CMEX2 instruments.
