The Depth Sensor will need to be zeroed out each time it is used. This ensures that the depth
sensor adjusts for ambient air pressure which can vary from day to day and at different locations
due to elevation and the weather. To zero the depth sensor open the Sonar Interface Advanced
Settings:
Open the Sonar Interface settings page by selecting Tools->Settings from the main menu. Select
Sonar->Interface. Then click on the Advanced Settings Button.
Click on the Zero Pressure Reading Button. This offset is stored in the arc_sonar.ini file and will be
used every time the ARC Explorer interface driver is started.
