Troubleshooting
1. Use a suction or compressed air device to remove any loose particles from the
sealing surface and other adjacent areas in the sensor cavity.
Note
Do not scratch or deform any part of the sensor, sensor cavity, or sensor nut threads.
2. Carefully brush the sealing surface clean with a soft bristle brush.
3. Moisten a cotton swab with an appropriate cleaning liquid.
4. Wipe the sealing surface. Repeat several times if necessary with a clean cotton
swab until there is minimal dirt residue picked up by the cotton swab.

Sensor installation
1. Carefully place sensor over the post in the sensor cavity.
Note
If the meter body is at an elevated temperature, let the sensor rest on the post to warm up
before proceeding to the next step.
2. Insure that the sensor is centered on the post. See view “A” in Figure 7-12 for an
example of improper installation and view “B” in Figure 7-12 for an example of
proper installation.
