Maintenance and Troubleshooting 8-3
Inspecting the Monitor
Perform the following inspections during site visits or from a
remote location (when applicable):

Inspect the monitor mounting bracket to verify that the bracket
and bolts are free of heavy corrosion and the bolts are tightened
and secure.

Verify that the four bolts holding the monitor together are snug,
and tighten any loose bolts.

Verify that the monitor is mounted securely in the manhole.

Inspect the monitor for general integrity. Verify that nothing
more than surface corrosion is present and that the monitor has
no obvious mechanical defects. Replace the monitor if
necessary.

Perform monitor data confirmations. These should occur from a
remote location when wireless communication is available.

Review the applicable logs in Profile ® to verify the status of
the monitor clock, communications, firmware, battery pack(s),
and temperatures.

Clean the monitor and sensors regularly with a soft bristle
brush and paper towels. However, do not use detergent!

Make sure all connector ports on the monitor top are dry. Use
compressed air or paper towels to dry out wet or damp
connectors.
Confirming the Monitor
Confirm the accuracy of the sensor subsystems in the monitor on a
regular basis. Confirmation involves comparing manually-measured
depth of flow and velocity readings to the monitor's readings. This
process also verifies sensor parameters. Refer to the Profile User's
Guide
(#950015**) for detailed information on performing
confirmation procedures.
