OXYGEN SENSOR CARE
! WARNING: In the event of a faulty sensor, all three sensors should
be replaced together as it cannot be guaranteed that the scenario
that made the first sensor fail has not affected all the sensors.
! WARNING: Number each individual sensor before removal so they
can be replaced in the same position.
Basic care includes:
•
NEVER store sensors in any gas other than air.
•
NEVER subject sensors to high temperatures i.e. (Car trunks).
•
NEVER freeze sensors (left in cars overnight).
•
NEVER subject sensors to physical shocks.
•
NEVER subject sensors to vacuum.
•
NEVER submerge sensors in liquids.
•
Never attempt to open a sensor housing.
• Sensors deteriorate very slowly and near the end of their useful life may
show a reading drift soon after calibration.
• Always change all 3 sensors together and after a maximum of 12 months
from first usage or the "Do Not Use After" date printed on the sensor,
whichever comes first.
• Water and corrosion on the sensor jack plug may give false Oxygen
readings. Seawater may dry leaving a deposit on the jack connectors and
the sensor membrane. If you suspect corrosion, remove the sensor from
the sensor module and clean the jack plug with a cloth and DeoxIT® GN5
contact cleaner.
