If the correct fuel is displayed, press ENTER to confirm the
selection.
•
If it is not correct press the cycle button to cycle through the
internal list of fuels.
•
Press ENTER when the desired fuel is displayed.
Once a fuel has been selected, a range of other functions are
available and assigned to the F1, F2, F3 function buttons as shown in
Figure 4-2.
Use the cycle button to scroll line by line through the available
functions. Note that the on screen representation of F1, F2 and F3
change appropriately to the named function.
It may be more convenient to alter the position of some functions
so that they appear on the same line. For instance, if you routinely
change fuels, make a measurement then , print and save the data, it may
be more efficient to have “fuel”, “print”, and “save” buttons on the same
line to avoid having to constantly scroll back and forth to the various
lines. Use the Change Layout button to move all three functions to the
same line.
