Measuring procedure
1.) For a correct measurement please ensure that the device has
the same temperature than the material under test (+/-3°C). For
that reason, let your humimeter SLW adjust to the surrounding
temperature of the material for at least half an hour before
measuring.
2.) Switch on the device: Press the key for 3
seconds.
3.) Changing the calibration curve: Press the
key once and then the or key. The name
of the calibration curve can be seen at the
head of the display.
4.) Push the electrodes into the yarn or textile.
Within a second the water content is shown
on the display.
6.) To save the results in the save menu
press the ( button). The storage was
successful when the number in front of the
symbol increases. To reach the store menu
please press ( ) until the appears.
7) To name the saved results press the button.

List of calibration curves
Pressing the or key during the
measurement for at least 3 seconds a list with
all available sorts will appear. Select your sort
by pressing or and confirm it with the
key. The measurement will continue
automatically.
Measuring value
The measuring value shown on your humimeter SLW represents
the “water content” of the testing material (textile). This means that
no conversion from “textile moisture” into “water content” is
necessary. If you prefer to change the shown value into “textile
moisture”, please contact
Definitions:
Water content
The water content is the amount of water in a textile referred to its
total weight. For example: 1kg of a textile with 40% water content
consists of 0.4 kg water and 0,6 kg textile.
Textile Moisture
The textile moisture is the amount of water in a textile referred to its
dry weight. The same example: 0.6 kg textile with 0.4 kg water; the
0.6 kg of the textile represents 100%, so the 0.4 kg of water are
66.7% textile moisture.

Transfer of saved data to the PC
To send your saved logs to the PC, connect
the humimeter device to your PC using the
USB cable that was delivered with your
device. Carefully loose the protection cap on
your humimeter and plug in the USB mini B
connector. The bigger connector has to be
connected to a USB slot on your PC.
Start the LogMemorizer software on your
PC and switch on your humimeter SLW.
The data transfer can be started on your
humimeter or on the software:

3.) Put four new batteries in the device.
Make sure that the position of the
battery poles is correct.
4.) Press down the batteries and close the
cap.
If the battery symbol appears in the measuring
window resp. if a critical charge of battery is
shown in the status, the batteries have to be
changed IMMEDIATELY. If you do not use your

Exemption from liability
For miss-readings and wrong measurements and of this resulting
damage we refuse any liability. This is a device for quick
determination of moisture. The moisture depends on multiple
conditions and multiple materials. Therefore we recommend a
plausibility check of the measuring results. Each device includes a
serial number and the guarantee stamp. If those are broken, no
claims for guarantee can be made. In case of a faulty device,
please contact Schaller GmbH (www.humimeter.com) or our
dealer.
Device maintenance instructions
To provide a long life of your device please do not expose it to
strong mechanical loads or heat e.g. dropping it or direct sunlight
exposure. Clean your device using a dry cloth. The measuring
chamber needs to be cleaned with a dry and soft brush.
Any kind of wet cleaning damages the device. The instrument is
not rainproof. Keep it in dry areas. When the device is not used for
a longer period (6 months) or when the batteries are empty, they
should be removed to prevent a leakage of battery acid.

! IMPORTANT ! please read
Most common reasons for miss readings
• Product temperature out of application range
Material below 0°C resp. above +40°C (32 to 104 °F) may
cause faulty measurements. The storage of cold material in a
warm storage area usually creates condensed water which
may lead to major measuring errors.
• Not adjusted temperature of the device
Let your humimeter adjust to the surrounding temperature of
the material for approximate half an hour.
A very high temperature difference has a negative effect on
the stability of the measurement results.
• Wrong calibration curve
Before measuring, double check the correct selection of the
calibration curve.
• Water film at the measuring head
After measuring wet material a water film can arise on the
sensor head. This can lead to a too high measuring result for
the following measurements. After measuring wet material
clean both black plastic parts accurately with a dry cloth.
• Direct sun radiation
