Construction of the Data Logger The MeteoLOG TDL 14 data logger is a complete measurement system to detect and store meteorological data. The instrument is battery-operated, thus allowing it to be set up acc. to model and sensor equipment at site without any mains supply for some hours or even days. The exchangeable storage battery is situated in the data logger case. The case, which can be locked, is water-tight (IP65) and very sturdy. The case is made of stainless steel to protect the instrument from electro-magnetic fields. Furthermore, operation in a temperature range from -30° to 50°C is guaranteed. The instrument is easy to operate, either with the three keys or over the serial interface. The three keys are indicated by "<∆>", "<∇> on" and "<enter>" in the following. The instrument has a two-line, alphanumeric display. Numerous inputs are available for the connection of measured data transmitters (sensors). A maximum of 10 analog and 4 digital sensors can be connected. The measured values are saved time-controlled in a CMOS-RAM which has been secured against loss of data. This memory is organized as a ring memory and can save 256 KB. The data can be read out either over a serial interface (V.24/RS232-C or RS422) or over a memory card (option). The TDL14 with COM2 allows an additional output of the instantaneous data every second. The COM2 is not possible with the TDL14 with ultrasonic connection. An integrated lithium battery buffers the contents of the data memory and the clock operation when no other power supply is available. This means that the saved values and the time are not lost even when there is no additional power supply.

Selecting the memory output: "M" stands for mean values and extreme values "E" stands for extreme values Mean values press <∇> Extreme values press <∆> Mean values and extreme values can be stored in succession on the memory card. The buffer battery can only be replaced by the manufacturer. Switch the data logger on with the <∇> key.1. Press <ENTER>: data output starts. Either "E" or "M" appears in the second line of the display. the operational life of the buffer battery is 10 years.3. depending on what has been selected. the data logger starts. press the <∇> ON key and hold it down. only the self-discharge factor is of importance for the operational life. In addition "MCard" and the number of data records output also appear. The operational life of the storage battery is considerably reduced when operated below 10. Please note: 5. However. 9. Insert the memory card into the data logger holder Keep pressing the <∇> key until the words "data output" appear on the display. the storage battery should not be discharged below 11. When no power is drawn. 7.0 V as there is no appreciable capacity available anymore. Before the storage battery is disconnected. Continue to press the key (3 seconds) until the words "M-data" appear in the second line of the display. it is advisable to remove the battery. no measurements are carried out.The nominal operational life of the battery of the 256 KB memory card (type BS256F1-C) is 4 years.

Furthermore. data transfer approx.30 020879/11/05 . we basically recommend that you only set the measurement cycle to greater than or equal to one minute.00X 24 . in case of pure accu-solar operation the GSM-online periods should be brief In the following we show how to calculate the current consumption for both modes of operation. 55 mA (RS422 connect with Interface Converter) The measurement current consists of a permanent component Iquery and a current Isensor which is dependent on the connected sensors. 2. For these cases the additional current consumption must be added to the calculated values.

The capacity depends greatly on the temperature: For operation below 0° assume only half the capacity. For the data logger in mains-independent operation (only storage battery and solar panel).1740. because two different processor modes are employed. The total current Imean can be calculated as follows: Iquery Imean = Icont + Measurement cycle [s] + Isensor * 0. = approx.2 QUERY MINUTES 1) As with QUERY SECONDS.
