7.3 i40 Depth operation
When connected to the relevant depth transducer, your i40 depth
instrument:
• Provides depth information, in either feet (ft), metres (M) or
fathoms (FA).
• Records the minimum depth encountered during the period the
unit is switched on.
• Enables you to define alarm thresholds for shallow alarm, deep
alarm, shallow anchor alarm and deep anchor alarm.
• Enables you to see what offset has been applied to the depth
reading.
Note: The required depth units are selected during User
calibration.
It should be noted that:
• Up / Down depth-trend arrows are displayed, if the seabed is
rising or falling at a significant rate.
• Minimum depth reading is reset to zero at power up.
