It is recommended to repeat the measurement in a few points situated next to each other as humidity
has a tendency of uneven distribution. If the measurements vary, only the highest outcomes should
be used.

To switch off the meter press ON/HOLD button for around 2 seconds.
3. Preparation of the surface before measuring
All concrete heating/drying equipment should be switched off at least 96 hours before taking the fi-
nal measurements. Otherwise the outcome may not reflect the actual humidity level or displacement
of humidity in tested material. Before the measurement may be taken, the analyzed surface should
be cleaned- there should not be any foreign substances like plastic films, dust etc.. In case of measuring
concrete floors all covering materials like: concrete additives, primers, paints, etc., should be removed
in order to reveal pure concrete that is going to be measured. All cleaning and cover-removing works
should be finished at least 48 hours before taking the measurement. PCE-PMI 4 meter should not be used
to measure concrete on which there is water in a liquid state. Measurements should be avoided in areas
exposed to direct sunlight or other sources of heat.
4. Available scales
1. Concrete (0-6% H
Concrete scale may be used only for concrete surfaces. It shows the relation between weight of pure
water contained in the tested material with its dry weight. The scale range varies between 0 and 6%
as 6% is about maximal physically possible content of water in the concrete. The obtained results sho-
uld not be confused with moisture emission or any other humiditymeasurement methods.
2. Cement Screed (0-6% H
This scale is used to measure the moisture content of cement screed. The content of water isexpressed
as a percentage of weight.
3. Cement Screed (0-4% CM)
This scale is used to measure the moisture content of cement screed. The displayed value is an approxi-
mate value that can be also determined using the Carbide Method (CM).
