Pressure AutoCal
The Pressure AutoCal function is used to set the local air pressure value as the
reference for calibration. By default, the calibration pressure is set to standard
atmospheric pressure.
Note: To AutoCal a logger, the pressure connection pipe for the
appropriate channel must be disconnected and the logger sensor must be
open to the ambient air pressure that will be used as the calibration
value.
To run the AutoCal function, select the Pressure AutoCal option from the
PrimeLog menu. PrimeWorks opens the Read Configuration dialog
instructing the user to verify that the logger is connected to the PC’s serial port.
Read Configuration dialog
Connect the logger to the serial port, and click on the OK button. The progress
will display in the lower right section of the main window.
Once communication is complete, the Pressure AutoCal dialog will display.
Note: Autocal is available only for loggers recording data from
pressure or depth transducers.
The dialog displays the serial number, site name, and logger type. Select the
checkbox corresponding to the Sensor Information channel on which to
perform the AutoCal process.
Verify that the logger pressure transducer pipe is not connected to the logger,
and then click on the AutoCal Now button to initiate the AutoCal process.
Once the process is complete, an AutoZero Setting dialog will display the
depth value representing the calibration factor that has been measured and set.
