Changing Batteries
Battery Type:
Two standard AA Alkaline batteries.
Because changing the batteries involves opening the water-tight seal,
this must be
done in a clean, dry environment to avoid contamination or moisture damage
to the circuitry.
Tips
• Never place a tool on the sensor body, it is very thin and will deform causing
leaks at o-ring seals and potentially crushing the circuit board!
• Always twist the sensor body off the top cap assembly rather than twisting the
top cap assembly off of the sensor body.
• For cabled sensors, always clamp the sensor on the swaged area when applicable,
the shoulder above it will allow you to press down without the worry of the
sensor slipping out of the clamping device.
• If the sensor body is slippery or you are unable to grip it hard enough to twist, try
a piece of rubber cabinet liner for additional friction.
Opening the Housing
There is a black, compressible square ring near the top of the sensor. This ring acts as
a spring to lock the cable in. This needs to be compressed in order to allow removal of
the top cap. Once this ring is compressed, a gentle counterclockwise twist is all that is
needed to remove the cable from the sensor body. Compressing the black square ring
does take force,
twisting does not
.
Cabled Sensor Cableless Sensor
Care must be taken to compress the black square ring before attempting to twist the
housing.
Forceful twisting of the housing can permantently damage the sensor
