3.3. Calibration
The ITL40 display can be calibrated five different ways: 1-point (quick calibration), 2-point (level calibration) empty
then full, 2-point (level calibration) full then empty, 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 “password error” pattern on the display (“X”
flashed four times). 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 (empty then full) RLLR LLRL (see section 3.3.2)
2 point (full then empty) RLLR LRRR (see section 3.3.3)
5 point (start at empty) RLLR LRLR (see section 3.3.4)
9 point (start at empty) RLLR RLLR (see section 3.3.5)
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 showing the number “1”. The display will then
start normal operation with the new calibration by displaying FULL (all LEDs on).
3.3.2. 2 Point Calibration (empty then full)
1. Enter the password RLLR LLRL. The display will respond by showing the number “2”. The display will then
begin scrolling the text “SET EMPTY” across the display.
2. Make certain that the tank is EMPTY and then activate the RIGHT switch to store that point. The display will
flash the top two LED rows and then begin scrolling the text “SET FULL”.
3. Fill the tank and then activate the RIGHT switch. The display will respond by flashing the top two LED rows
and then start normal operation with the new calibration by displaying FULL (all LEDs on).
3.3.3. 2 Point Calibration (full then empty)
1. Enter the password RLLR LRRR. The display will respond by showing the number “2”. The display will then
begin scrolling the text “SET FULL” across the display.
2. Make certain that the tank is FULL and then activate the RIGHT switch to store that point. The display will
flash the top two LED rows and then begin scrolling the text “SET EMPTY”.
3. Drain the tank and then activate the RIGHT switch. The display will respond by flashing the top two LED
rows and then start normal operation with the new calibration by displaying EMPTY (cascading LEDs).
