INSTALLATION
Installing the Sensor
For Barometric Measurement
Box version
The PT2X-BV box version can be installed in any position;
however, it is tested at the factory in the vertical position.
Therefore, when installing the transmitter outdoors,
Seametrics recommends installing it in a vertical position
to avoid moisture entering the inlet. Seametrics also
recommends installing a sun shield to avoid overheating.
Tube version
The PT2X-BV tube version can be installed in any position;
however, when it leaves the factory it is tested in the vertical
position. Strapping the sensor body with tie wraps or tape
will not hurt it. Be sure to install so that air inlets will never
be submerged. Seametrics also recommends installing a
sun shield to avoid overheating.
For Vacuum Measurement
If installing a vacuum tube for vacuum measurements,
be sure that the tubing is not collapsible. The box unit is
provided with a detachable Quick-Connect (QC) with a
male 1/8” pipe tting. Attach the tubing to the QC using
an appropriate tube tting for the tubing chosen. Attach
a tting to the inlet male QC designed to seal the tubing
of your choice. Seal the tting to the QC by using sealant
or PTFE tape. Connect the male QC to the inlet QC of the
PT2X-BV and the other end of the tube to the vacuum
source using appropriate ttings.

Settings and Calibration
Settings and calibration values can only be changed when
there are no les stored on the sensor. Be sure to retrieve
any data and then erase the data before continuing.
The temperature channel rarely needs adjustment. If you
think your temperature channel needs adjusting, contact
your service representative.
Before leaving the factory your PT2X-BV was inspected
using precision instruments. However, you can adjust the
settings, if needed, as shown below.
When using a barometric sensor, you may want to change
the channel label at the top of the Settings window to read
“Barometric Pressure.”
Note: Be sure to use the same units for all measurements
on this page. For example, if you have the program set
to display in psi then be sure to enter the barometric
pressure as psi.
-- Computing Oset --
• Using a barometric pressure indicator or other measuring
device, determine the current barometric pressure.
• Enter this value in the REF box..
• Click the Measure button.
• When readings have stabilized to your satisfaction, click
the Accept button in the pop-up box.
-- Applying oset --
• Click the Apply button to apply calculated oset.
• The calculated oset will be transferred to the oset eld
near the top of the window.
• Click OK to save the value to the sensor!!!
