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 deployments 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 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.
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.
