z After the software is downloaded and the configuration information is entered,
test for proper monitor operation by following the confirmation procedures
outlined in the next section, “Data Collection and Confirmation,” and in the
QuadraScan User's Guide.
Data Collection and Confirmation
QuadraScan software retrieves data over telephone lines or onsite from a monitor and
places it into a collection device. Data is confirmed by periodically verifying the data’s
accuracy.
Use the following procedure to perform a confirmation.
z A field crew member enters the manhole and directly measures the depth of
flow and velocity data. The field crew reports these independent
measurements to the QuadraScan operator at the central computer.
z At the same time, the utility software retrieves the flow data collected by the
monitor. The software can command the monitor to perform a data
conversion.
z These values retrieved from the monitor are recorded along with the field
crew's direct measurements. To test the monitor's data collection accuracy, an
analyst reviews the difference between the manually-measured flow values and
the monitor's measured flow values.
QuadraScan software contains step-by-step procedures for managing data collection
and confirmation. These procedures are beyond the scope of this document; refer to
the QuadraScan User’s Guide for more information.
