Section 3 Replace batteries
Explosion hazard. If the batteries are not installed correctly, explosive gases can be released. Make
sure that the batteries are of the same approved chemical type and are inserted in the correct
orientation.
If the user thinks that a sensor has water in the pressure housing: Disconnect the sensor from any
power supply. Put on safety glasses and make sure that the sensor is pointed away from the body
and other people. In a well ventilated area, use the purge port (if the sensor is so equipped), or very
SLOWLY loosen the bulkhead connector to let the pressure release.
If the user thinks that the alkaline batteries have leaks, pressure may have built up inside of the
pressure housing. Follow ESD protocols to release internal pressure. Put on safety glasses and
protective gloves and make sure that the sensor is pointed away from the body and other people. In
a well ventilated very SLOWLY loosen the bulkhead connector to release the pressure. Keep away
from heat, sparks, flame, and other sources of ignition. Do not smoke.
