BUTTON fUNCTIONS

• Press the release button (9) to turn the product on or off.
• Press the laser button (3)
- once to activate the dual-target laser (2),
- twice to activate the backlight of the display (5),
- three times to deactivate the target laser, or
- four times to deactivate the backlight.
• Press the button MODE (7) to toggle between the various display units in the top half of the
display:
- Dew point temperature ("DP" indicator)
- Ambient temperature ("AT" indicator)
- Ambient humidity ("%RH" indicator)
• Press the button ºC/ºF (6) to switch between the temperature units Celsius and Fahrenheit.
NOTES ON THE mEASURING pROCEDURE
a) Operating principle
• IR thermometers measure the surface temperature of an object. The sensor on the device
records the heat radiation emitted, reflected and transmitted from the object, and converts
this information into a temperature value.
• The emission level is a value used to describe the energy radiation characteristics of a
material. The higher the value, the more capable the material is of emitting radiation. Many
organic materials and surfaces have an emission level of approx. 0.95. Metallic surfaces
or shiny materials have a lower emission level and therefore return inaccurate measured
values.
• The ambient sensor measures the ambient temperature and humidity. From this, the
dew point is calculated. The infrared sensor measures the surface temperature and then
compares it with the calculated dew point temperature. The closer the value of the surface
temperature is to the dew point temperature value, the higher the risk of mould formation on
the measured surface.
b) Measurement distance / measurement surface area ratio (D/S)
• To achieve accurate measurements, the target must be larger than the thermometer's
measuring area. The measured temperature is the average temperature of the area
measured.
• The smaller the target, the smaller the measurement distance between thermometer and
target object has to be.
• The distance to target / size of IR focal spot ratio is 12:1. With a distance of 12 cm to the
target, the size of the IR focal spot is thus 1 cm.

mAkING mEASUREmENTS

1. Turn the product on and activate the target laser (2), if required.
The measuring surface is in the middle between the two laser points. The closer you are
to the surface, the more accurately you can aim on the desired measuring surface.
The maximum distance from the measuring surface should not be greater than 2 m.
2. Now start scanning the surface slowly. Point the IR sensor (1) as vertically to the measuring
surface as possible.
3. In the lower display (5) area, the surface temperature of the measuring surface will be shown.
In the upper display area, the ambient sensor (8) reading will be shown.
4. The right-hand side of the display shows the bargraph display. The higher the bar indicator
is, the greater the risk of mould formation.
5. The 3-colour warning LED (4) is located above the display. When the LED lights up
- green, there is no risk of mould formation.
- yellow, there is an increased risk of mould formation.
- red, there is an acute risk of mould formation, or the measuring surface has already been
affected by mould.
6. If the yellow LED lights up, in addition a beep tone will sound. If the red LED lights up, in
addition a continuous beep tone will sound.

mAINTENANCE AND CLEANING

• The device requires no servicing on your part apart from occasional cleaning. Only use a soft,
anti-static and lint-free cloth for cleaning.
• Do not use abrasive or chemical cleaners.
DISpOSAL
a) product
Electronic devices are recyclable waste and must not be disposed of in the household
waste!
At the end of its service life, dispose of the product according to the relevant statutory
regulations.
b) (Rechargeable) batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/
rechargeable batteries. Disposing of them in the household waste is prohibited!
Batteries/rechargeable batteries that include hazardous substances are labelled with
these icons to indicate that disposal in domestic waste is forbidden. The descriptions
for the respective heavy metal are: Cd=cadmium, Hg=mercury, Pb=lead (the
designation is written on the rechargeable battery e.g. under the rubbish can symbols
depicted at the left).
You can return used batteries/rechargeable batteries free of charge at the official
collection points of your community, in our stores, or wherever batteries/ rechargeable
batteries are sold!
You thus fulfil your statutory obligations and contribute to the protection of the environment.
