  • Page 4: Introduction

    Introduction General Warning! Certain parts in this electrical device contain dangerous voltages during operation. Failure to observe the warnings could therefore result in severe personal injury and/or damage to property. Only suitably qualified staff should work on this device or in its vicinity. These should be thoroughly familiar with all warnings and maintenance measures according to this Manual.

  • Page 5: Application

    Application The FIDAMAT 5E is an analyzer for measuring total hydrocarbons. It operates according to the principle of flame ionization. The analyzer is suitable for measuring all gaseous hydrocarbons. A heated line must be used for the connection to prevent condensation and adsorption in the gas line.

  • Page 6: Design

    Design The device is available either as a bench-top unit fitted in a housing, or without a housing for installation in a 19-inch rack or 19-inch cabinet. The FIDAMAT comprises two main sections, the analyzer section and the electronics with front panel controls.

  • Page 7: Mode Of Operation

    Mode of Operation Electrons are released when hydrocarbons are combusted in a hydrogen flame. These electrons are collected at an electrode by means of an electric field and measured using a highly sensitive amplifier. The current is proportional to the quantity of organically-bound C atoms in the sample gas.

  • Page 26: Organization Of Data Storage

    User-specific data Current data. All parameters required to operate the FIDAMAT 5E are stored in the EPROM and are protected by hardware (basic factory-set data). These data can be loaded into the current parameter memory using function 53. The user-specific data set is overwritten in the process, however. The basic factory-set data can only be overwritten by a hardware intervention.

  • Page 27: Maintenance, Warnings And Error Messages

    Maintenance, Warnings and Error Messages Maintenance In the FIDAMAT 5E it is only necessary to regularly service the pump. It is recommendable to replace the pump diaphram every six months. The pump can be removed from the front of the analyzer.
