Section 3 Replace alkaline batteries
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.
The pressure housing contains Electrostatic Discharge (ESD) sensitive parts and assemblies that
are susceptible to damage from ESD. Follow ESD protocols:
• Put on protective eye wear before you open the pressure housing.
• Any electrostatic charge on the body of the human operator must be released before the
pressure housing is opened: put a hand on a grounded surface, or better, wear a grounded
antistatic wrist strap.
• At a minimum, wear short-sleeved antistatic clothing, such as cotton, or better, wear an antistatic
smock for this service activity. Do not wear a sweater, fleece or polyester-based clothing.
• At a minimum, use a workstation with a wood or metal tabletop, or better, a tabletop that
dissipates static. Do not use a workstation with a synthetic or polymeric-based tabletop.
1. Use a clean cloth to dry the outside of the battery end flange. Make sure to remove any water at
the interface between the pressure housing and the end flange.
2. Use a wrench on the white plastic bar to turn the end flange counterclockwise to loosen.
