9 Point Calibration
1. Enter the password RLLR RLLR. The unit will respond by flashing the
two center LEDs nine times. The unit 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 unit 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 unit 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 unit 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 unit 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
unit 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 unit 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 unit 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 unit 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 unit
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).
Calibration data is saved in non-volatile EEPROM and the unit does not need
power to retain calibration data.
Calibration automatically makes the unit a master if the calibration is valid. An
invalid calibration is determined if any point is not at a higher level than the
previous, 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 unit previously will alterna-flash the outer two
LEDs, while a Remote will revert to Remote operation.
