ADS Environmental Services FlowShark QR 775003 A2 - Manual (Page 204)

Maintenance and Troubleshooting 8-19
Some problems that occur will not require a site visit, such as
incorrect equipment identification numbers or other system
parameters the user can re-enter on the local PC. However, other
problems will require a site visit. When this is necessary, inform the
data analyst any time a field crew is en route to a monitor site to
troubleshoot problems so that the analyst can attempt to collect the
monitor data before they arrive. If the problem is a faulty monitor
and the analyst cannot collect the data remotely, replace the monitor
and deliver the faulty monitor to the office so the analyst can
attempt to collect the data directly. Then, send the monitor to ADS
for repair.
This section provides general guidelines for troubleshooting and
correcting problems with the FlowShark IS monitor and sensor
subsystem.
