2.6 INITIAL SET UP OF THE FUEL COMPUTER
Your fuel computer features the capability of 'remembering' the SIZE
of your fuel tank. This is setup once after you receive your system, or
if for some reason the fuel computer memory has been lost. (NOTE:
A lithium battery module is located inside the DPU and will require
replacing about every eight to ten years.) Setting up the ‘FULL TANK
SIZE’ parameter is done by performing these steps:
STEP 4. With power ON, move the FUEL MODE SELECTOR SWITCH
to the blank position between 'GPH' and 'OK' and wait for the
display to blank-out and shut off power.
STEP 5. Turn on power and the display should now be showing 'FULL
?', which means the computer is 'asking' you if you want to set
up the SIZE of your tank.
STEP 6. Move the switch to the 'ADD' position and wait until the digital
display equals your aircraft's tank SIZE. To reduce the SIZE,
simply move the switch to the 'SUB" position and the display
will count back down.
STEP 7. When reaching the desired SIZE, quickly move the MODE
switch back to the blank position. The display will show 'rdy'.
Wait for this message to disappear.
STEP 8. Move the switch to 'TOT' position and shut off power. This
completes the setting of the 'FULL TANK SIZE'.
