The user can do tests on the sensors that make up the WQM to make sure that they
operate correctly.
1.
Make sure that the sensor is in
In Standby
.
2.
Go to the
Help
menu, then select
Troubleshooting
.
3.
Select a sensor to test from the Select Test Mode drop-down menu.
•
Test CTD-DO sensors
•
Display CTD Cal Coefficients
—shows the calibration information that is
stored in the sensor.
•
Take One Sample
—The sensor operates to collect one measurement.
•
CTD
Sampling: "StartNow/Stop"
—The sensor operates to collect data until
the user pushes
Stop
.
•
Display CTD Status
—Shows the operation settings that are stored in the
sensor.
•
Set Output Rate
—Select the slider in the area below to set the number of
measurements.
Important
: the calibration for the ODO sensor is accurate for
approximately 200,000 samples, and then the precision of the collected data
decreases.
•
Test internal optical sensors
•
Display Setup
—Shows the operation settings that are stored in the sensor.
•
Take One Sample
—The sensor operates to collect one measurement.
•
Close Bio-wiper
—The Bio-wiper moves to a closed position.
•
Open Bio-wiper
—The Bio-wiper moves to an open position.
•
Test CTD pump
•
Turn pump On
/
Turn pump off
—Turn the pump on or off.
•
Test external data port—
•
Display Setup
—Shows the operation settings that are stored in the sensor.
•
Take One Sample
—The sensor operates to collect one measurement.
•
Test analog inputs—not currently available
•
Setup/test SBE18S
•
Display Status
—Shows the operation settings that are stored in the sensor.
•
Take One Sample
—The sensor operates to collect one measurement.
•
Start Continuous Sampling/Stop Sampling
—The sensor operates to
collect data until the user pushes
Stop
.
•
Configure SBE18
—Shows the operation settings that are stored in the
sensor.
•
Set SBE18 baud rate—The default is 9600. The user can select a faster rate
to move collected data from the sensor
4.
Select a test to do from the test area that shows to the right of the sensor drop-down
menu.
5.
Push
Test is Complete
to go back to the drop-down menu and select a different
sensor to test.
6.
Push
Close Tab
when tests are done.
5.10 Horizontal deployment
The sensor can be deployed in a horizontal position if necessary. The sensor cannot
easily remove air bubbles from the plumbing in this position. Make sure that the intake
duct is higher than the exhaust duct. This will aid the pump to fill with water and operate
