Caution: Do not exceed the specified pressure ratings of the P•Xchange™ sensor.
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.
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, MVP•X instruments are
rated to 6000m, but are limited by the depth rating of the installed P•Xchange™ sensor. 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. There are four available
pressure ranges offered with the MVP•X: 500dBar, 1000dBar, 4000dBar, and 6000dBar.
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.

Secondary Xchange™ mount blanking plug
Post-Deployment Procedures
When the instrument is pulled from the water, it should be rinsed in fresh water.
Dry the area around the connectors with a clean cloth or compressed air prior to
disconnecting the plugs or cables.
Do not blow compressed air into the
Pressure•Xchange™ sensor. Doing so may damage the sensitive pressure transducer
diaphragm.
Remove the shorting plug or cable, and place the dummy plug in the connector to protect
it.
Dry the instrument and stow it securely.
