Adjusting calibration points manually
You may want to set individual calibration points manually. For example you may find
that your fuel level is over reading at a specific fuel level. Correcting the tank level
reading for this area can be simply done by adjusting the calibration point. You can do
this by moving the float level with your hands to the desired position and then performing
the calibration as outlined above, or you can use the manual option.
Select
“MANUAL”
for the mode menu item. Then highlight the point you want to change
manually and press the rotary control. Use the up or down keys or the rotary control to
adjust the value. Press the rotary control when done.
Note:
The calibration positions may be edited by using the rotary control. This allows you, in theory, to copy calibration
settings from one instrument to another. We however recommend that you do go though the calibration procedure even if
the two aircraft are identical in all respects. Tolerances do exist and the calibration cancels these out. Accurate fuel level
displays are a vital safety factor for an aircraft and a very useful feature for peace of mind during cross county flights.
Notes on Slope error
Sender value is a value determined by the FLIGHT-3. It is used to calculate fuel level,
fuel endurance estimate and current range estimate. The fuel tank setup sender value
can either increase in value as fuel is added or decrease in value if fuel is added. This is
dependent on the type of fuel level sender used. However should the second reading be
larger than the first reading all readings will have to be larger than the previous readings.
Likewise should the second reading be smaller than the first reading all readings will
have to be smaller than the previous reading.
If this is not the case the wording "Slope error" will be displayed. This could happen when fuel was removed instead of
added between steps, no fuel was added between steps or when the fuel level sender was moved in the wrong direction
e.g. moving the fuel level sender manually when it is not inserted in to the fuel tank. Determine the cause of the error if
you should get a slope error message. If you do not know the cause of your error it is best to start from scratch. It should
be remembered that accuracy in the fuel tank calibration is extremely important to enable your FLIGHT-3 to display the
correct data.
