cumstances.
• Prevent the following adverse conditions at the location of installation and during
transport:
- Extreme cold or heat, direct sunlight,
- dust or flammable gases, fumes or solvents,
- strong impacts, blows.
• Do not leave packaging material carelessly lying around, since it could become a
dangerous plaything for children.
• Handle the product with care; it can be damaged by impacts, blows, or accidental
falls, even from a low height.
• Do not use in the immediate proximity of strong magnetic or electromagnetic fields
or transmission aerials. These can affect the measurement.
• The measuring instrument is suitable for use in dry or damp conditions. Avoid use
in a damp or wet environment.

chapter "Technical data".)
Inserting / replacing batteries
Unscrew two screws on the back and open the battery compartment.
Insert a new battery or replace the old battery with a new one.
Close the battery compartment again and secure it with the screws.
The measured data are retained during battery change.
If more than 10 seconds are needed for the change, then the clock will have to be
set again via a software.
The display switches off approx. 20 minutes after the last key function.
General Battery Instructions
• Batteries should be kept out of the reach of children.
• Do not leave batteries lying around in the open; there is a risk they may be swallowed by
children or pets. If they are swallowed, consult a doctor immediately.
• Leaking or damaged batteries can cause burns if they come into contact with the skin. You
should therefore wear suitable protective gloves.
• Batteries must not be short-circuited, opened or thrown into a fire. There is a risk of explosion.
• Make sure that the polarity is correct when inserting the batteries (pay attention to plus/+ and
minus/-).
Installation and general information
• This data logger shall be placed in vertical position. At low temperatures and high air humid-
ity, the data logger shall be put into vertical position for condensed water evaporation before
reading the data on the device.
• Some battery power can be conserved when the data logger is connected to a PC.
a) Measuring ranges
The data logger has an integrated temperature and humidity sensor, and two external tempera-
ture sensors can be connected as well.
The internal temperature sensor has a measuring range of -40 °C to +70 °C.
Each of the two external temperature sensor inputs on the data logger has a measuring range
of -200 °C to +1300 °C.
Important!
T he K-temperature sensors supplied with the temperature logger are suitable
for a temperature range of -20 °C to +250 °C only.
Temperature sensors of different temperature ranges are available as accessories.

b) Cable lock
Included within the scope of delivery you will find
a small cable lock. This can be used to secure
the data logger in the wall holder against unau-
thorised removal. Accordingly, the wall holder
has an opening suitable for the cable lock.
