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.
Calibrate the unit by entering the desired point calibration password –
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.
