6. When the display shows the correct number of senders, press the BATT
button to exit the programming mode. Each tank will need to be
calibrated individually using this procedure.
To calibrate the LPG sender:
1. The LPG tank must be full when the sender is calibrated, otherwise the
calibration will be invalid. Fill the LPG tank by using an alternate
measurement method, such as weight, a spit valve, or a mechanical
gauge on the tank.
2. To calibrate, press and hold down the LPG button, the display will show
some LPG level.
3. While continuing to hold down the LPG button, press and hold down the
BATT button. Continue to hold down both buttons for about 5 seconds
until the display shows the LPG calibration code.
4. When this occurs release both buttons, the display will shut off,
completing the calibration procedure.
5. The LPG can be recalibrated as many times as desired, although
recalibration should not be needed unless the LPG tank sender or the
display has been replaced.
The battery voltage is calibrated at the factory, this should never need to be
changed.
