Appendix K: Using the EAGLE 2 in Bar Hole Mode
Overview
This chapter explains how to operate the EAGLE 2 in Bar Hole Mode. Bar Hole Mode is
used to perform consistent checks of bar holes when tracking down underground gas
leaks. When the EAGLE 2 is in Bar Hole Mode, only the combustible and oxygen sensors
are displayed.
If an EAGLE 2 is intended for bar hole testing, it is shipped with Bar Hole Mode or both
Bar Hole Mode and Leak Check Mode enabled so that the operator must choose which
operational mode to use when the unit is turned on (see “Updating LC/BH Mode Setting”
