6-2 ADS 3600 Flow Monitor O&M Manual
Remote Confidence Checks
Review the QuadraScan hardware logs to verify the normal status of the monitor
clock, local monitor communications, the monitor BASIC code, the battery status, and
the monitor temperatures. Replace the battery when the battery status indicates low
(an approved technician must replace the battery in QS3600 flow monitors).
Note: Local confidence checks are made onsite during a visit to the monitor
location. You can perform local confidence checks on the monitor and on the
flow sensors.
Monitor
Inspect the monitor mounting bracket to verify that the bracket and bolts are free of
heavy corrosion. Verify that the bolts are secure in their moorings. Provide other
mounting brackets as necessary. Verify that the four bolts holding the monitor
together are snug. Tighten the bolts if they are loose. Verify that the monitor is still
securely attached inside 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 confirmations following the instructions provided in Chapter 5 and in
the QuadraScan User's Guide.
Review the QuadraScan hardware logs to verify the normal status of the monitor
clock, local monitor communications, the monitor BASIC code, the battery status, and
the monitor temperatures.
Communication with the IS modem or with the modem located in the EMU can be
checked remotely by calling the monitor.
Maintaining the Battery Pack
Check the battery status in QuadraScan before installing the monitor and after
collecting data. If a battery’s status is low, the battery should be replaced.
The QuadraScan User's Guide outlines the procedure for requesting the battery
voltage and status. When you request the battery voltage using QuadraScan, the
battery status reads OK until the battery pack voltage falls below a fixed threshold, at
which time the battery status reads Low. If QuadraScan reports that the battery status
is low, the battery should be replaced as soon as possible (within the week). If the
battery is completely dead, the monitor will not be able to respond to the QuadraScan
request for the battery status.
