5. Fill the tank to the three-quarter tank point and then activate the RIGHT switch. The display will flash the top
LED and then turn on all four LEDs.
6. Fill the tank to the full point and then activate the RIGHT switch. The display will respond by flashing the top
LED then lighting the two center LEDs and then reverting to normal operation by displaying FULL (all LEDs
on).
3.3.4. 9 Point Calibration
1. Enter the password RLLR RLLR. The display will respond by flashing the two center LEDs nine times. The
display will then begin cascading the LEDs from top to bottom (drip).
2. Make certain that the tank is EMPTY and then activate the RIGHT switch to store that point. The display will
flash the top LED and then begin flashing the bottom LED.
3. Fill the tank to the one-eighth point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom LED.
4. Fill the tank to the one-quarter tank point and then activate the RIGHT switch. The display will flash the top
LED and then turn on the bottom LED and flash the second LED.
5. Fill the tank to the three-eighths point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom two LEDs.
6. Fill the tank to the one-half point and then activate the RIGHT switch. The display will flash the top LED and
then turn on the bottom two LEDs and flash the third LED.
7. Fill the tank to the five-eighths point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs.
8. Fill the tank to the three-quarter point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs and flash the fourth LED.
9. Fill the tank to the seven-eighths point and then activate the RIGHT switch. The display will flash the top
LED and then turn on all four LEDs.
10. Fill the tank to the full point and then activate the RIGHT switch. The display will respond by flashing the top
LED then lighting the two center LEDs and then reverting to normal operation by displaying FULL (all LEDs
on).
3.3.5. Calibration retention
Calibration data is saved in non-volatile memory (EEPROM) and the display does not need power to retain
calibration data.
3.3.6. Invalid calibration
Calibration automatically makes the display a master if the calibration is valid. An invalid calibration is determined
when any calibrated point is not at a higher level than the previous calibrated point, or if the transducer voltage falls
outside of the valid minimum (.4V) or maximum (4.8V) range. An invalid calibration is acknowledged by giving the
“wave off” and if this was a master display previously will show an “invalid calibration error” (section 3.1.3), while a
Remote will revert to Remote operation.
3.3.7. Calibration incomplete
If the calibration is not completed the display will continually flash the “incomplete calibration error” (section 3.1.3),
during all subsequent power cycles. This indicates that a calibration was attempted but never completed.
Recalibrate the display completely to remove this error condition.
3.4. Self test
The Tank Level can check its hardware for proper operation by entering the password RLLR LLRR.
The display will then cycle each LED ON individually starting with the bottom LED and then all LEDs will come on and
begin flashing between full bright and the calibrated dim level for 5 seconds. The display will then show the condition
of the self test for 5 seconds.
