Concrete Encounter CME 4
User Guide
24/08/04
floor slab obtained on this scale indicate moisture
content measurement
and should not be confused with
lbs emission
or any other unit of measurement obtained
by other moisture testing methods or meters. It should
also be noted that there seems to be no linear correlation
between moisture content measurements and lbs
emission measurements as obtained using calcium
chloride testing methods.
4. For gypsum and other floor screeds, comparative or
qualitative readings should be taken from the middle, 0
to 10, scale of the meter dial.
5. Alternatively, the lower, 0 to 100, reference scale can be
used for comparative readings. This scale is not to be
interpreted as a measurement of percentage moisture
content, or relative humidity. It is not a relative humidity
reading and it does not have any linear correlation with
Relative Humidity measurements. This scale should be
regarded as a comparative or qualitative scale only. This
scale is included to facilitate comparative testing of
different areas where direct contact with the bare
concrete surfaces may not be possible due to some form
of thin coating or covering on the concrete, or additive
in the concrete that could influence the readings.
Readings from the reference or relative scale are
comparative only and of help in identifying areas with
moisture problems.
6. The CME 4 will automatically power-off after four
minutes if no button is pressed or if no change in meter
reading is detected. If a button is pressed or the meter
reading changes, the power-off will be extended for an
additional four minutes.
7. To freeze readings press the HOLD button once.
While
on HOLD, the upper LED will flash slowly. If the unit
powers OFF while on HOLD, the frozen meter reading
is digitally memorized and restored next time ON is
selected. To remove freeze, press HOLD button again.
