Calibration
You do not have to perform a new calibration when using the Go Direct Wide-
Range Pressure. The sensor is calibrated prior to shipping. If you would like to
perform your own calibration, follow the steps described here. A one-point
calibration at atmosphere is adequate for most applications.
To perform a one-point calibration,
1. Connect Go Direct Wide-Range Pressure to a device and launch the software.
2. Initiate the calibration procedure.
3. Enter the actual pressure as the known value.
4. When the relative stability reading stabilizes, click Keep.
5. Click Apply to complete the calibration process. This calibration is
automatically saved to the sensor. To restore the default calibration, click
Reset to Defaults.
Go Direct Wide-Range Pressure has been calibrated to read station pressure.
Station pressure
is the true atmospheric pressure at your location, or station. If you
prefer it to read sea level pressure for conducting weather studies, you can perform
a one-point calibration to correct for elevation, using the sea-level corrected
pressure value for your location obtained from a reputable source (NOAA,
Weather Underground, etc.). Sea level pressure is the pressure after the station
pressure has been adjusted to its equivalent pressure at sea level. This is
commonly done to normalize pressures at various altitudes for weather forecasts.
Pressure in Liquids: Depth Measurements
If you measure the pressure at the end of a long plastic tube forced underwater,
you can indirectly measure depth. Connect the tubing to the stem of Go Direct
Wide-Range Pressure and then put the end of the tube under water. The pressure
reading will increase 8.105 kPa (0.0800 atm or 60.79 mmHg) for every meter
below the surface of the water.
Note:
If you measure depth in this way, the depth
you are measuring is to the top of the water in the tubing.

Identifying the Sensor
When two or more sensors are connected, the sensors can be identified by tapping
or clicking Identify in Sensor Information.
Using the Product
Connect the sensor following the steps in the Getting Started section of this user
manual.
To switch quick disconnect fittings, simultaneously press the metal tab on the
quick fitting adapter that is on the pressure sensor side of the connection while
pulling the attachment away from the adapter. Once the desired attachment is
