This device allows you to make detailed recordings of the temperature and humidity and to actively monitor them. Recorded data can be transferred to a computer using a USB transceiver for easy analysis. The supplied software can also be used for managing the logger and can be used purely as windows service to provide datasets to your own software application. The logger is able to use up to eight outdoor transmitters.

DCF RADIO CONTROLLED TIME RECEPTION

• After the KlimaLogg Pro has searched for external transmitters for three minutes, the device begins to search for the DCF signal (german radio-controlled clock signal), and the DCF reception indicator flashes. If the time code has been received after 5-10 minutes, the radio-controlled time is displayed and the DCF reception indicator remains on the LCD.
• In case the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance, etc.), the time can be set manually. 
• The clock will then work as a normal quartz clock. (see: Basic settings/Time and calendar). 
• The radio controlled clock receives the signals at 2:00 and 3:00 o'clock in the morning. 
• As soon as the clock has received the DCF signal, the manually set time will be overwritten by the DCF time.
• Note that during reception of the radio-controlled clock signal, no communication with the USB wireless transceiver is possible or may be briefly interrupted. 

Note for Radio Controlled Time DCF:
The base for the radio controlled time is a Caesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1500 km. Your Logger receives this signal and converts it to show the precise time in summer or wintertime. The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1,500 km radius around Frankfurt.

Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 metres.

Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter.

During night-time, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.

IP Rating

An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress. Click for a table of IP Rating values.

Table of IP rating values

IP65 - No ingress of dust (6); Protection from water ingress: Low pressure jets of water (5).
