press and hold the ENTER/TEST button until the screen
starts to flash and then release the button. The first screen
after the “Good” will display the K-factor for the left engine
in the left side of the screen with the right side of the screen
showing the units of measure (i.e. gallons, pounds, etc). The
next screen will be blank on the left side and the right side
will display the K-factor for the right engine (if applicable).
If the correct K-factor(s) is/are displayed, the procedure was
successful.
