Install or Replace EXO 1 Batteries
EXO1 water quality sondes use two (2) D-cell batteries as a power source. Using alkaline batteries, users can
expect approximately 90 days of deployment from a fully loaded sonde that samples once every 15 minutes.
However, deployment times may vary greatly depending on water temperature, sampling rate, sensor payload,
and brand of battery. *See battery life specification, next page.
1 Remove battery cover.
Start with a clean and dry sonde. Hold the sonde
horizontally with the bail up and twist the battery
cover counterclockwise until free. If necessary, slide
the sonde tool's larger opening over the end of the
battery compartment and use it as a lever to break the
compartment free. Then slide off the battery cover.
A
Do not remove the screws on the sonde.
Do not clamp the sonde in a vise.
2 Remove old batteries.
Expose the batteries by flipping the isolation flap up away
from the batteries, and pull the batteries free of their
compartment. Always dispose of used alkaline batteries
according to local requirements and regulations.
Clean the inside of the battery compartment with a lint-
free cloth.
3 Install new batteries.
Install the new batteries so that the positive terminals point
towards the bail (away from the sensor bulkhead). Replace
the isolation flap over the batteries.
