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. The sensor leads connect to the analog PCB.

The main PCB is mounted in the top half of the case. It includes the methane elimination and CAL/SETUP switches.

CAUTION:The circuit boards should be serviced only by authorized repair personnel.

Methane Elimination Switch

The methane elimination switch (SW1) is mounted near the top right corner of the main PCB.

For applications where methane is an interfering gas, you can set the methane elimination switch to eliminate most response to methane (see “Appendix B: Methane Elimination” on page 52). An external methane elimination switch is available as an option.

CAL/SETUP Switch

The CAL/SETUP switch (SW2) is mounted near the middle left edge of the main PCB.

This switch controls the Eagle functions available to the user by disabling the SHIFT/▼ button. Without the use of this button, the user is unable to enter Calibration or Setup mode. (Display mode is available with either switch setting.) See “Setting User Access” on page 13 to change the switch setting.
