    Introduction Overview The RKI Eagle is the most advanced portable gas detection system available. The Eagle is built for rugged reliability and ease of use and includes the latest innovations in gas detection technology: • Simultaneous detection of one to six gases. Standard target gases include combustible gas (% LEL and ppm), oxygen deficiency, carbon monoxide, and hydrogen sulfide.

  • Page 9: About This Manual

    About this Manual This manual is intended for use with all Eagle models. Examples used in this manual are for the standard four-gas model (combustible gas, oxygen, carbon monoxide, and hydrogen sulfide). Differences between the standard four-gas model and other Eagle models are noted where applicable.

  • Page 12: Description

    Description Case The Eagle has a plastic case with a full-sized handle. The high- visibility case is shielded to reduce radio frequency and electromagnetic interference (RFI/EMI). The system is light-weight and balanced, which makes the Eagle easy to carry and use for extended periods.

  • Page 13: Alarm Lights

    Alarm Lights Two ultra-bright, red, light-emitting diodes (LEDs) provide visual alarms for gas concentrations and malfunctions. They are mounted on the top rear of the case for greatest visibility. Battery Charger Connector The battery charger connector is mounted on the top right rear of the case.

  • Page 14: Sensors

    Sensors This section describes the Eagle’s standard sensors. Non-standard sensors are described in Appendices C, D, and E. Your specific Eagle model may not include all of the sensors described below. Under normal conditions, the Eagle’s standard sensors have an operating life of approximately two years.

  • Page 15: Circuit Boards

    Circuit Boards The Eagle circuit boards analyze, record, control, store, and display the information collected. The analog PCB is mounted perpendicular to the base of the instrument case. It is located in the same half of the case as the sensors and sample-drawing system.

  • Page 16: Operation

    Operation The Eagle has four operating modes: normal operating mode, display mode, setup mode, and calibration mode. This section describes the Eagle in normal operating mode. It includes procedures to start up the Eagle, set various detection options for the combustible gas channel, and shut down the Eagle.
  • Page 17 The Battery Voltage screen displays the minimum usable and actual battery voltage (for example, 6.0V). If the battery voltage is too low, the Eagle will not continue. NOTE: The following screen only displays if the data logging option is installed. If the data logging option is not installed, the Self Diagnosis screen displays after the Battery Voltage screen.

    Appendix F: Eagle Tank Tester Model The Eagle Tank Tester model is intended for checking tanks or vessels that may contain residual hydrocarbon vapors or water or may have been purged of oxygen. You can also use this model as a standard Eagle gas monitor by connecting the standard hose and probe and updating the oxygen alarms to the default settings.

    Dilution fitting (1:1) CAUTION: When measuring oxygen readings, remove the dilution fitting or use your finger to seal the small dilution hole on the side of the dilution fitting. The standard combustible gas sensor requires oxygen to operate. In environments where there is not enough oxygen to operate the combustible gas sensor, (for example a tank purged with an inerting gas), the 1:1 dilution fitting adds sufficient oxygen by blending ambient air with the incoming sample.

  • Page 78: Calibration

    Calibration Use a hexane calibrating source to calibrate the combustible gas LEL range. Use a 100% nitrogen calibrating source to set the zero reading for the oxygen channel. RKI Instruments, Inc. recommends using the Single Calibration method to calibrate the Eagle Tank Tester model. See “Calibration”...

    Appendix H: Eagle Transformer Gas Tester Model This Eagle Transformer Gas Tester Model is specially set up for electrical transformer gas testing. Large electrical transformers are filled with oil which surrounds the transformer coils, and they have an inert gas head space above the oil. When a transformer begins to fail, electrical arcing between the conductors of the coils can cause flammable gases to form in the head space.

    NOTE: The EAGLE can be calibrated either with or without the dilution fitting in place. If calibrated without the dilution fitting in place, then display readings must be doubled to determine the actual gas concentration. If calibrated with the dilution fitting in place, then the sample bag must be used during calibration, and the display readings will be the actual gas concentrations.
