Display mode Trip (button 3)
This display mode shows:
- Fuel used after last zeroing
- Instantaneous fuel consumption (amount of fuel
used per hour) (If speed information is available, in-
stantaneous fuel consumption can also be calcula-
ted in relation to distance.)
- Operation time after last zeroing
- Total operating time (can not be zeroed)
If you want to zero the trip values (trip fuel consump-
tion and trip operating time), keep button 3 depres-
sed for 1 second. The unit beeps and the values are
zeroed.
Note!
When the display is set for a twin engine installation,
the information displayed for each engine will be
the sum of the values from both engines, apart from
operating time. Operation times for twin engines are
shown separately.
The size of the operating hours figures shown on the
display is reduced if the number does not fit in the
window.
Display mode Graph (button 4)
In this display mode, operating information is display-
ed in the form of a histograph. Press button 4 repea-
tedly to show different operating information.
If an item of operating information is not available, that
window can not be chosen.
If contact with the relevant information is lost during
display, the curve will no longer be drawn, but the line
will continue to scroll across the window.
Data for the port engine or single engine information
is drawn with a black line.
Data for the starboard engine information is drawn
with a gray line.
The maximum time interval can be set to one of the
following values in the configuration menu: 2 min, 10
min, 30 min, 1 h, 2 h, 4 h, 8 h.
The interval on the Y axis is automatically adjusted for
best indication.
