Page 11: 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 12: Alarm Lights
Alarm Lights Two ultra-bright, red, light-emitting diodes (LEDs) provide visual indications for gas alarms and instrument malfunctions. They are mounted on the top rear of the case for greatest visibility. Battery Charger Connector The battery charger connector is at the top right rear of the case. The external battery charger connects to this connector to recharge nickel-cadmium (Ni-Cd) batteries. -
Page 13: Sensors
The standard probe includes a replaceable particle filter and hydrophobic filter disk that prevent particulates and water from entering the Eagle’s flow system. See “Replacing the Probe’s Particle Filter and Hydrophobic Filter Disk” on page 43 for instructions to replace the particle filter and hydrophobic filter disk. Sample Hose Standard Probe... -
Page 14: Circuit Boards
Oxygen Sensor The oxygen (O ) sensor is mounted face down in the sensor block to allow the sample flow to diffuse into the sensor. A multi-pin plug connects the O sensor to the CN2 socket on the analog PCB. The O sensor is an electrochemical cell, which reacts to the oxygen in the atmosphere and produces a voltage proportional to the oxygen concentration. -
Page 15: 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.
