g. If you want to continuously monitor the next tank, press the button again to hold on that tank. Note,
however, that it will only be monitored for 2 ¼ minutes minus the time that the previous tank was
monitored. So if the previous tank was monitored for 1 minute, then the current tank will only be shown for
1 ¼ minutes before the display shuts down.
h. If you are really the impatient sort, and want to quickly advance to one of the tanks that is displayed
near the end of the cycle (the fresh water tank for example), then press the button twice during each
unwanted tank level to advance immediately to the next tank.
To continuously monitor the LPG level for calibration:
1. The value of this procedure is not to continuously observe the LPG level during filling, but to be able to
easily calibrate the display to the LPG tank sender. It is not advisable to run the gauge during tank filling
since flammable gas may be present in the vicinity of the tank sender. Even though the power levels to the
sender are very low, a fault or short circuit could occur which may apply higher power levels to the sender.
2. Fill the LPG tank to a known level (usually the 80% point) to have a known amount of LP Gas in the
tank.
3. Press the button and release it, the display will power up and cycle through the battery voltage and
holding tanks.
4. When the LP Gas level is displayed, press the button. While it is held down you will see "dlA"
indicating that the display will proceed to the diagnostic functions. If you hold the button down longer than
about 8 seconds the display will shut itself off.
5. When the button is released, the display will start cycling through the sender diagnostics. After the fresh
water tank sender diagnostics are done, the LP GAS LED will light and the LPG level will be continuously
displayed. You may notice a slight flickering of the display as the system repeatedly reads and displays the
LPG level.
6. The LPG tank level can now be calibrated by turning the control inside the display.
7. To turn off the display press the button. While it is held down you will see "End" indicating that the
display will proceed to shutdown. If you hold the button down longer than about 8 seconds the display will
shut itself off. Releasing the button will cause the display to immediately shut off.
8. If the display is left on the continuous LPG level, it will turn off after about 2 ½ minutes.
To review the sender diagnostics:
1. The sender diagnostics should be reviewed periodically to check for any degradation of the tank senders.
If a sender appears to be malfunctioning, reviewing the diagnostics should be the first step.
2. Press the button and release it, the display will power up and cycle through the battery voltage and
holding tanks.
3. When the LP Gas level is displayed, press the button. While it is held down you will see "dlA"
indicating that the display will proceed to the diagnostic functions. If you hold the button down longer than
about 8 seconds the display will shut itself off.
