•
The density of the measured material is an important factor to the measured value. The
measured value increases with density.
•
A main field of application for this device is for comparative measurements, comparing
measured values against a reference value. The reference value is established by measur
-
ing a similar or identical material at a clearly dry area. If the subsequent measurements are
much higher than the reference value, it can be deduced that the areas being measured
are damp. This procedure is well suited for water damage assessment, to detect leaking
locations and areas of high humidity.
b) Measuring the moisture content
1.
Turn the measuring device on by using the on/off button
(5)
. The device automatically
switches into HOLD
(12)
mode, i.e. no measurement is possible at this stage.
2.
The measurement device has to be calibrated each time it is turned on. To calibrate it, hold
the measuring device up in the air, so that it does not touch any objects. The minimum
distance to any other surface should be 8 to 10 cm. Press the MEAS button
(7)
to start the
calibration.
3.
During calibration, the LCD will show <CAL>.
4.
After completion of the calibration, the LCD
(6)
will display the current humidity reading
(10)
. This value should be less than 0.5. If not, turn the measurement device off and repeat
the calibration.
5.
Position the humidity sensor’s spherical head
(1)
at a right angle to the surface. The display
will show the reading.
6.
Move the measurement device to conduct measurements of larger surface areas. The LCD
should thereby display the current reading as well as the maximum
(11)
and minimum
reading
(16)
.
7.
If required, press the MEAS button to freeze the readings on the display. The display will
show HOLD, in addition to the last measured reading.
8.
The readings are then displayed on the LCD for another 60 seconds, before the measure
-
ment device turns itself off.
9.
Alternatively, in HOLD mode press the MEAS button to continue measuring.
c) Setting the alert function
The meter also display three non-numerical formats of measurement : DRY, RISK and WET.
When the moisture status is at RISK and WET, the meter emits beeping alert noises.
At RISK level, the meter will beep about once every second.
At WET level, the meter will beep about three times every second.
By default, a moisture reading of < 30 is indicated by DRY; 30 - 60, by RISK; above 60, by WET.
Different materials have different tolerance of moisture. For more information, refer to Technical
Data under chapter 9. To program your threshold range:
1.
When the HOLD icon
(12)
is displayed, press SET to enter the alert mode.
2.
The RISK icon will blink. Press UP
(2)
or DOWN
(4)
to adjust the lower threshold value for
RISK. The value can be adjusted from 0 to 50. Press SET to confirm your choice.
3.
The WET icon will blink. Press UP
(2)
or DOWN
(4)
to adjust the lower threshold value for
WET. The value can be adjusted from 50 to 100. Press SET to confirm your choice.
4.
The LCD returns to the initial display.
5.
The threshold value is permanently stored until it is changed next time.
d) Backlight
When the HOLD icon is displayed, press UP to switch the backlight on or off.
Care
Clean the device as necessary with a soft damp cloth that is lint-free. Do not allow moisture to
penetrate into the housing. Do not use sprays, solvents, cleaning agents that contain alcohol or
abrasives; instead use only clean water to moisten the cloth.
Disposal
a) Product
Electronic devices are recyclable waste and must not be disposed of in the house
-
hold waste. At the end of its service life, dispose of the product in accordance with
applicable regulatory guidelines.
Remove any inserted batteries and dispose of them separately from the product.
b) Batteries / rechargeable batteries
You as the end user are required by law (Battery Ordinance) to return all used bat
-
teries. Disposing of them in the household waste is prohibited.
Contaminated batteries are labeled with this symbol to indicate that disposal in the
domestic waste is forbidden. The designations for the heavy metals involved are:
Cd = Cadmium, Hg = Mercury, Pb = Lead (name on batteries, e.g. below the trash
icon on the left).
Used batteries can be returned to collection points in your municipality, our stores or wherever
batteries are sold.
You thus fulfill your statutory obligations and contribute to the protection of the environment.
