NOTE: Setup mode allows you to select between alkaline and Ni-Cd
batteries. The two types of batteries have unique low battery
alarm characteristics. To prevent unexpected low battery
alarms, always make sure the battery type setting in Setup
mode matches the type of batteries installed in the Eagle.
Replacing the Probe’s Particle Filter and
Hydrophobic Filter Disk
Inspect the probe’s internal components if you notice that the Eagle’s
pump sounds bogged down or if an unexplained low flow alarm
occurs. Replace the particle filter if it appears to be dirty. Replace the
hydrophobic filter disk if it appears dirty or saturated with liquid.
Replace the O-rings in the probe if either of them appears damaged.
1. Grasp each end of the clear probe body firmly and unscrew the
two halves from each other. One half includes a plastic tube fitting
and the probe tube. The other half includes a metal fitting that
mates with the sample hose or Eagle inlet fitting if it is a standard
probe. This half has a plastic fitting if it is a super toxic probe.
