General application and safety information

2.1

Antenna position

Range approx. 
1000m

The range (always dependent upon the structural conditions of the building such as cement ceilings, water 
pipes etc.) is approx. 100m in a typical office environment 

 5.1 

Radio settings

.

In which direction 
should
the antenna 
point?

With this type of antenna, the signal is emitted at right angles from the antenna. The direction can be 
visualized as being like a CD that is skewered on the antenna. This makes it clear that it is best for the 
antenna to be placed vertically, pointing upward, so that it transmits to all rooms on the same floor. If the 
antenna is placed horizontally, reception is best on the floors above and below.

Metal objects such as shelves, reinforced concrete walls, ventilation and energy shafts, but also the 
opening of a refrigerator door can lead to the weakening of the signal. This kind of effect is usually very 
much limited to the location.
Moving the wireless sensor within an area of 2.5 meters (sometimes just a few centimeters) is usually 
adequate to completely change the reception ( 

 3.1.1 

Transmitted frequency & radio channel

). Move 

the wireless sensor forward, backward, up and down within this area. The wireless sensor should always 
be mounted at least 1.5m above the ground.
If no direct line of sight to the wireless sensor is available, the angular position (angle in relation to the 
horizontal axis and rotation of direction) can improve reception.
Placing the wireless sensors in an open stairwell is an additional possibility to avoid one or more reinforced 
steel ceilings that are an obstacle.

Temperature effect

Technical data

.

- It can't be guaranteed that the loggers will function properly if the datalogger is exposed to 

temperatures which exceed the specified threshold range. Experience shows that at storage 
temperatures below -50°C, the battery freezes, measurements are no longer taken and setpoint 
tracking may be temporarily interrupted. Once it has been returned to room temperature, the logger 
must be reprogrammed before it can be used again.

- At temperatures below - 20°C, the display is not easily readable; however, longterm use is not 

affected.

- For longterm use above 40°C, lithium battery passivation can lead to temporary reading problems 

(self-discharge protection), which can be resolved with repeated utilization.

- At temperatures above 45°C, battery self-discharging increases. With long term use above 45°C, the 

battery lifetime can be reduced by about 1/3. 

- Exposure to temperatures above 55°C can result in permanent discoloration of the display.
- There is danger of a gas explosion if the lithium battery is heated to temperatures exceeding 100°C.

2.3

Exceptional environmental conditions

Pay attention to the following when using the wireless sensor in exceptional environmental conditions:

- IR radiation (heat) and superheated steam can damage the surface coating of the casing
- There is a risk that the battery may explode if the logger is used under microwave radiation

Initial startup

THE WIRELESS SENSOR MUST BE AT ROOM TEMPERATURE BEFORE INITIAL 
STARTUP!
