The OMD-2008 EVFC is designed in that way, that only the measuring cell needs to be changed, as this unit carries the Calibration Certificate. The Calibration Certificate with the date of the last calibration check should be retained onboard for inspection purposes.

  • Page 12: Construction

    DECKMA HAMBURG GmbH 5 Construction 5.1 Overview OMD-2008 instruments consist of two main components: The Computer Unit contains the display PCB with the data logger and the terminals for external connections. The Measuring Cell assembly consists of the Measuring Cell, a valve to select sample water stream, or clean water stream, and, depending on the version of the instrument, additional devices like a flow sensor.

  • Page 13: Other Devices

    5.4 FW valve The OMD-2008 uses a switchover valve to control the usage of clean water for cleaning, or zeroing purposes. Whenever the FW valve is switched to Clean water position, and not to sample stream position (normal operating position), the instrument will be in alarm condition.

    If the sample flow rate is too small, the instrument will be in Alarm and display “Status: Flow”. On instruments fitted with Manual Cleaning Unit (OMD-2008 EV-FC MCU), sample a higher or a lower flow rate can be adjusted. To get the higher flow rate, remove the smaller O-Ring (9.5x2) from the Manual Cleaning Unit.
