Inspecting the Monitor
Perform the following inspections during site visits or from a
remote location (when applicable):
z Inspect the monitor mounting bracket to verify that the bracket
and bolts are free of heavy corrosion and the bolts are tightened
and secure.
z Verify that the four bolts holding the monitor together are
snug, and tighten any loose bolts.
z Verify that the monitor is mounted securely in the manhole.
z 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.
z Perform monitor data confirmations. These can occur from a
remote location where wireless communication is available.
z Review the applicable logs in Qstart
XML
to verify the status of
the monitor clock, communications, firmware, battery pack,
and temperatures.
z Clean the monitor and sensors regularly with a soft bristle
brush and paper towels. However, do not use detergent!
Note: Please use special care when cleaning the crystals
on the Surface Combo or Ultrasonic Depth sensor. They
are covered with a Teflon
®
coating. Therefore, do not use
a wire brush or other abrasive, metallic device to clean
these sensors.
