4. Anhydrite Screed (0-3.5% H
This scale is meant for moisture measurements in anhydrite floors. The displayed value is an approxi-
mation of a value that normally would be indicated using a CM-measurement device.
5. Anhydrite Screed (0-1.9% CM)
This scale is used to measure the moisture content of Ascreed. The displayed value is an approximate
value that can be also determined using the Carbide Method (CM).
6. Caisson Skala 0.3-15.3 (0.3-15.3 m)
Scale works in a similar way as the Relative with a range from 0.3 til 15.3m.
7. Relative Skala 0-100%
Relative scale may be used in humidity level comparison of various materials. Obtained results sho-
uld not be interpreted as percentage content of water in tested surfaces. There is no linear correlation
between the outcomes and relative humidity. The scale should be used only as comparison technique.
Scale may be used on the surfaces where direct contact with pure concrete is impossible because
of some layer/covering.
5. Modes & Functions
Normal mode
The main measuring method of PCE-PMI 4 meter is Normal mode. In this setting the
measured value is refreshed continuously.
Max. Hold mode
If the measured area is not easily reachable and it is impossible to read the value while me-
asuring, the Max. Hold mode may be used. After choosing that mode the measured value
is not refreshed continuously. The meter will show only the highest value gained from numerous me-
asurements. After switching to normal mode and then back to max hold operation, the value measured
in this mode is set to zero.
Caution: Even single touching of sensor plate or electrodes during this mode will cause a highly inaccurate outco-
me. That in turn will result in the need of repeating the whole measurement process. The measurement in that set
may be repeated by switching the mode into Normal and then into Max.Hold again.
Auto turn-off
In order to maximize batteries lifetime, the meter automatically turns off after 12 minutes.
This function is always active and can't be switched off.
Service Info
This mode enables to check some meter service information which include:
•
total working time,
•
quantity of switching-on,
•
software version,
•
date of production,
•
batteries voltage.
This mode may be accessed by pressing and holding the SET button for 5 seconds and then by
pressing ON/HOLD button simultaneously. All the information will be shown as long as the SET
button will be held.
