Using the Instrument
Pressure Ratings
Pressure ratings are given for Xchange™ sensors and the entire instrument.
Deployments should
never exceed the lower of these two pressure ratings.
For example, a 500m instrument equipped
with a 6000 dBar (0-
6000m) P•Xchange™ sensor is limited to deploymen
ts of 500m depth or less.
Similarly, a 6000m instrument equipped with a 500 dBar (0-
500m) P•Xchange™ sensor is also
limited to deployments of 500m depth or less.
It is desirable to optimize the accuracy of pressure measurements by using a P•Xchange™
sensor
with a pressure range that closely matches the depth of the deployment.
Pre-Deployment Procedures
•
Upon Receipt
o
Use the Shipping and Receiving instructions to verify the condition of the instrument.
o
Verify that all sensor calibrations are valid for the duration of the deployment. If not,
swap the
Xchange™ sensors for sensors with valid calibrations or send the
Xchange™ sensors to a service centre for recalibration.
o
Lightly lubricate the underwater connectors with 3M silicone spray or equivalent.
•
Before leaving the jetty
o
If applicable, verify the P
•Xchange™ pressure range is correct for the deployment.
o
Connect the instrument to a computer using the data cable.
o
Check the instrument memory
▪
Save any unsaved memory files.
▪
Initialize the memory (Note: This deletes ALL files stored in the instrument
memory. Be sure to have a copy of all important logged data before
performing this step.).
•
If using SeaCast, click the
Clear Memory
box.
•
If using a Terminal Emulator, send instrument an
INIT
command.

Caution: Do not exceed the specified pressure ratings of the P•Xchange™
sensor, Turbidity•Xchange™ sensor, or the instrument housing.
Overpressure can result in damage to the sensors and the instrument.

Caution: Install blanking plugs in all unused sensor ports prior to deployment. Failure to install
blanking plugs will result in damage to the connectors.
