7.2 i40 Bidata operation
When connected to the relevant transducer(s) your i40 Bidata
instrument:
• Provides speed information (current, maximum and average), in
either knots (KTS), miles per hour (MPH) or kilometers per hour
(KPH).
• Provides log and trip information. These are given in either
nautical miles (NM), statute miles (M) or kilometers (KM).
• Provides water temperature information. This is given in either
degrees celsius (ºC) or degrees fahrenheit (ºF).
• 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. This can be reset at any time.
• Enables you to dene alarm thresholds for shallow alarm, deep
alarm, shallow anchor alarm and deep anchor alarm.
• Enables you to see what offset is applied to the depth reading.
Note: The required speed, distance, depth and water temperature
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 signicant rate.
• The log screen shows the total distance covered by the vessel
since the unit was tted.
• Minimum depth, maximum speed, average speed and trip reading
are reset to zero at power up.
i40 Bidata Display
The display is split into upper and lower data areas, each of which
shows either depth or speed information, depending on user
selection.
The Current speed, Current depth and Current water
temperature pages are permanent pages, all other pages are
temporary and will time-out after 5 seconds, to the last permanent
page displayed.
Switching the depth and speed position
1. Press the Action button to switch speed and depth positions
on the display.
