  • Page 15: Nox Measurement (Nox Standard)

    3.6. NOx measurement (NOx standard) The ecom-JN can be equipped with a complete NOx module which comprises: - NO sensor - NO sensor - Peltier cooled gas heat exchanger - Heated sampling system (3.5 m long) The instrument can also be equipped with only one sensor for measuring the NO concentration although no NOx calculation can be made in this case.
  • Page 16 3.) The set temperature is reached after approx. 5 minutes and is then controlled by the programme. 4.) Be sure to connect the condensation tubing when using the heated sampling system and gas cooler to avoid problems due to condensation being pumped off. Page 16 ecom-JN...

  • Page 17: Data Processing

    4. Data processing The ecom-JN data processing package consists of : - RAM card slot - Extended software - External keyboard - Centronics parallel port - Optional: RAM cards in different sizes (standard 512 kB) The extended software enables additional functions for storing and administrating measurement results as well as long term measurements with data logging.

  • Page 18: Data Base / Ram

    Once the measurements are completed, the data can be transfered back to the PC in the correct form and under the correct area. To do this an area of the RAM card must be reserved. Page 18 ecom-JN...
  • Page 19 Data is transferred from the PC via the RS 232 port from a particular programme (e.g. the regional administration software). To do this the RS 232 port on the ecom-JN is connected to the serial port on the PC. C o m m u n i c a t i o n...

  • Page 21: Working With Chip Cards

    4.2. Working with chip cards Only for instruments with chip card slot! The ecom-JN can read from and write to 512 byte chip cards. These data carriers which look like telephone cards, can store approx. 500 characters of information. A chip card can be used as a installation data card, a measurement file or as a job card.
  • Page 22 The standard data required is fixed as the length of the data areas. If a chip card is inserted into the ecom-JN, the data is read from the card into the instruments RAM.
  • Page 23 In many cases it is necessary to store additional information along with the measurement information already available. Up to now the data processing and handling using the ecom-JN has been done without paper using the most modern techniques. It is therefore only natural that any additional information is handled in the same way.

  • Page 24: Instrument Settings

    5. Instrument settings The ecom-JN functions are described in the previous sections. The calculated and measured values can be altered by changing certain options via the settings on the JN. Pressing <SET> when in the flue gas measurement mode accesses the options menu. Move the cursor to the relevant position and press <E>.
