INSERTING / REPLACING THE BATTERY
1. Open the battery compartment cover (10).
2. Connect a 9 V monobloc battery to the matching terminal inside the battery compartment.
3. Close the battery compartment.
R eplace the battery when the battery icon appears on the top right side of the display.
BUTTON FUNCTIONS
• Press the release button (9)
- once, to turn the product on.
- o nce during measurement, to freeze the readings last shown on the display. The indication "HOLD"
appears on the display (5). To continue with the measurement, press the release button again.
- for approx. 2 seconds to turn the product off.
• Press the laser button (3)
- once to activate the dual-target laser (2),
- twice to deactivate the target laser (2).
• 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 toggle the temperature display unit between Celsius and Fahrenheit.
- f or approx. 2 seconds to turn the beep on/off. The display (5) will show the symbol (beep on) or
(beep off).
NOTES ON THE MEASURING PROCEDURE
a) Operating principle
• I R 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.
• T he 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 sur-
faces have an emission level of approx. 0.95. Metallic surfaces or shiny materials have a lower emission
level and therefore return inaccurate measured values.
• T he ambient sensor measures the ambient temperature and humidity. From this, the dew point is calcu-
lated. 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)
• T o 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.
• T he smaller the target, the smaller the measurement distance between thermometer and target object
has to be.
• T he distance to target / size of IR focal spot ratio is 20:1. With a distance of 20 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.
T he 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
- g reen, there is no risk of mould formation.
- y ellow, there is an increased risk of mould formation.
- r ed, 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.
T he device will turn off automatically approx. 15 minutes after having been turned on with the
release button (9).
I f the HOLD function (press release button during measurement) is activated, the device turns off
automatically after approx. 20 seconds. Legal notice

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!
A t the end of its service life, dispose of the product according to the relevant statutory regulati-
ons.
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!
B atteries/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.
