General
Health threat by mould:
The formation of mould always goes along with an increased moisture
concentration in your room. Already a relative humidity of 70% encourages
the growth of mould in living spaces. Increased air humidity can be caused
by conventional activities in the household like cooking, taking a shower or
drying of laundry. Also plants and humans release water, which is emitted
into the surrounded air. Furthermore, in new buildings residual moisture from
building material can be released. In order to prevent an infestation or the
increased growth of mould spores in living spaces, simple measures like
reasonable ventilation and appropriate heating can be taken. If your living
area is already infested with mould, this should be treated rapidly and
effectively, and a new formation should be prevented. The appearance of
mould can also cause allergic reactions of the body as well as inflammatory
reactions and infectious diseases.
User manual
Function Preventing and avoiding mould:
Mount a wall hook on a position with increased potential of mould (e.g. outer
wall) and position the humimeter SW1 device on the hook. Switch on the
instrument by pressing the button for 3 seconds. Select the calibration
curve “Risk of mould” using the arrow keys or . The device switches on
regularly and checks the level of risk. In case of a high or very high risk of
mould an optical alarm is activated. The humimeter SW1 can be activated at
any time by pressing the button for 3 seconds. The instrument clearly
shows the level of risk (no/little/increased/high/very high risk of mould)
immediately.
Function ventilation monitor:
Switch on the instrument and select the calibration curve “Absolute humidity”
using the arrow keys or . Measure the absolute air humidity in a central
position of your room, and subsequently the absolute air humidity outdoors.
For that, go outside and leave the humimeter SW1 there for approx. 10
minutes. If the absolute air humidity outdoors is lower than the air humidity
inside the room, riskless ventilation is possible. On the other hand, if the
outdoor measuring value is higher than the indoor one, ventilation will
increase the risk of mould.

Function climate monitor:
Switch on the instrument and select the calibration curve “relative humidity”
using the arrow keys or . Measure the relative humidity in a central
position of your room and let it adjust to the surrounding climate for a few
minutes. The ideal interior air humidity is between 40% and 60% relative
air humidity. Too damp but also too dry air is felt as unpleasant and may
have significant negative effects on your health.
Calibration curves
Definition of calibration curves
Risk of mould:
The calibration curve “risk of mould” clearly evaluates the risk, grouped into 5
risk levels. The risk levels are related directly to the relative air humidity.

Absolute humidity:
shows the contained amount of water in gramme per cubic metre of air. The
absolute humidity is a direct degree for the amount of water vapour
contained in a certain air volume. It shows how much moisture can
maximally condense or how much water has to be evaporated to receive a
certain desired air humidity.
Relative air humidity:
indicates the relation between the current water vapour pressure and the
maximal possible water vapour pressure (called saturation vapour pressure).
The relative humidity shows the degree the air is saturated with water
vapour. For example:
50% relative humidity indicates that at the current temperature and the
current pressure the air is saturated with water vapour for half of its value,
100 % relative humidity means that the air is totally saturated. When the air
has more than 100 % of relative humidity, the excessive moisture would
condense or form fog.
Operating the instrument
Switching on: Press for three seconds.
Changing the calibration curve: or .
Menu: Switch on the instrument pressing the key and immediately, during
showing the start logo, press both arrow keys and and keep them
pressed until the main menu appears.
Setting date and time: Menu - Options – date / time
Set date and time using the button , according to the format indicated
(JJ.MM.TT). After entering the year, press the button for entering the
month and again for entering the day. For changing from date to time also
press the button . After finishing, press for saving the entered data.

Changing measuring interval: Menu – Options- Interval
Standard is a measuring interval of 15 minutes. To increase the battery life,
this interval can be exceeded to up to 12 hours. We recommend a measuring
interval of about 15 minutes to one hour.
Datalog: For activating the datalog, effect the following steps:
Unlock: Menu - Options – Unlock
The standard password is the 4-digit serial number. Insert the number and
confirm by pressing OK.
Changing user level: Menu - Options – O User level
For activating the advanced user, highlight this menu item.
Datalog time: Menu – Options – Datalog time
Select your desired interval (except Hold) using the arrow keys and confirm
by pressing OK.
Deactivating interval: Menu – Options – Interval
Select „off” by pressing the button and confirm by pressing OK.
Starting the Autolog / saving measuring values
Back in the measuring window press the key to reach the store menu. For
saving a measuring value or activating an automatic log, press the button.
For completing the AutoLog, switch on the device (if necessary) and press
the button. If you want to add additional data please press the button.
Additional data can also be entered on the PC subsequently.
For returning to the normal use, all menu items have to be reset:
Unlocking by entering the password, changing user level to single user O,
deactivating Autolog (or set to “manual”), changing the interval to 15 minutes,
returning to the measuring window.
Switching on the display lighting: Press the key briefly; the display
lighting switches off automatically after approx. 2 minutes. Pressing any key
activates the display lighting again.
Modifying display lighting time: Menu – Options – BL On Time
The period for display lighting can be modified by pressing the and
keys.
Auto off:
The instrument switches off automatically after approx. four
minutes.
Modifying Auto off time: Menu – Options – Auto Off time
The period for switching off can be modified by pressing the and keys.

Conditioning of the sensor
The conditioning of the sensor (time until the device shows the actual
measuring value) depends on several parameters. The parameter
responsible for the highest measuring error is a temperature discrepancy
between the sensors resp. the whole measuring instrument and the material
to measure resp. the air.
Care instructions
Do not drop the instrument or expose it to excessive temperatures. The
instrument is not waterproof. Do not immerse the sensor in liquid.
The intervals for checking the instrument depend on your operational
demands and the required level of accuracy. In general the drift of the sensor
according to the degree of use (constant humidity or use within the whole
moisture measuring range) is beneath 0.5% per year.

Exemption from liability
For misreadings 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.
Changing the batteries
Press with your finger onto the arrow of the battery cap and pull it back.
Remove the empty batteries. Put four new 1.5 Volt AA Alkaline batteries in
the device. Make sure that the position of the battery poles is correct. 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 humimeter device for a longer period,
remove the batteries. For eventual resulting damages
we cannot provide any warranty.
In case of a faulty device, please contact Schaller GmbH
(www.humimeter.com) or your dealer.
