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 0.3-15.3 Scale (0.3-15.3m) Scale works in a similar way as the Relative with a range
from 0.3 til 15.3m.
7. Relative Scale 0-100% Relative scale may be used in humidity level comparison of various
materials. Obtained results should 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 VI-D4 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
measuring, 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
measurements.
Caution: Even single touching of sensor plate or electrodes during this mode will cause a highly
inaccurate outcome. 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.
