The unit will respond by flashing the two center LEDs the same number of times
as the desired calibration. The unit will then indicate the level to be calibrated by
lighting the proper LEDs for that level starting with empty (see page 3, tank level
indications). When the tank is filled to the proper level for calibration (dictated by
the LEDs) activate the RIGHT switch to store that point. The unit will flash the
top LED and then set the LEDs for the next calibration point. Continue filling the
tank to the proper level dictated by the LEDs and storing that point with the
RIGHT switch until finished (after the FULL point has been calibrated). The unit
will respond to a completed calibration procedure by lighting the two center LEDs
and then reverting to normal operation by displaying the proper tank level, which
at this point should indicate FULL (all LEDs on) because the tank level is full.
To get out of calibration mode at any time without saving, activate the LEFT
switch.
Calibration data is saved in non-volatile EEPROM so 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.
Calibration in a nutshell.
1. Enter the password for the desired calibration (wait for center LEDs to
flash back the calibration number).
2. Ensure tank level is at proper level for calibration point as indicated by the
LEDs.
3. Activate the RIGHT switch to store point (Top LED flashes).
4. Continue steps 2 and 3 until finished (Full has been calibrated).
