3.3. Calibration
The ITL display can be calibrated four different ways: 1-point (quick calibration), 2-point (level calibration), 5-point and
9-point (volume calibration).
To enter calibration mode use a magnet and activate the magnetic switches in the order of the appropriate password.
Entering an invalid password will initiate a “wave off” pattern on the display. (Two
center LEDs, two outer LEDs flashing quickly for 8 cycles.) The unit will then
resume its normal operation and the user can attempt to re-enter the password.
Calibrate the unit by entering the desired point calibration password –
1 point RLLR LRRL (see section 3.3.1)
2 point RLLR LLRL (see section 3.3.2)
5 point RLLR LRLR (see section 3.3.3)
9 point RLLR RLLR (see section 3.3.4)
During calibration, the process can be cancelled at any time by activating the LEFT magnetic switch. This will
allow the display to exit without showing an “incomplete calibration error” (section 3.1.3) on the next power
cycle.
3.3.1. 1 Point Calibration
1 point calibration only calibrates the full point. The empty calibration is always set to 0.55V (approximately 1.5
inches of liquid).
1. Make certain that the tank is FULL.
2. Enter the password RLLR LRRL. The display will respond by flashing the top LED twice. The display will
then revert to normal operation by displaying FULL (all LEDs on).
3.3.2. 2 Point Calibration
1. Enter the password RLLR LLRL. The display will respond by flashing the two center LEDs twice. 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 turn on all four LEDs.
3. Fill the tank 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).
3.3.3. 5 Point Calibration
1. Enter the password RLLR LRLR. The display will respond by flashing the two center LEDs five 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 turn on the bottom LED.
3. 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 two LEDs.
4. Fill the tank to the one-half tank point and then activate the RIGHT switch. The display will flash the top LED
and then turn on the bottom three LEDs.
