8. To avoid mistakes, asks again if you are sure that 
you want to calibrate the unit. Press ( OK ) another 
time to enter. 
 
 
 
9. Pressing (+) we enter in High level calibration. 
 
 
 
 
 
10. If when you adjust the high level, the liquid in the 
tank is 80 % of the capacitance, we will indicate it in 
the display using the (+) and (-) keys. Confirm with 
(OK). 
 
 
11. The microprocessor makes the operations to 
calibrate the maximum level of the unit. This 
operation takes some seconds. 
 
 
 
12. The display shows this message to indicate NMC 
has finished the calibration internal process. 
When the liquid level will be in the minimum point, it 
will indicate 000.0 % and when the liquid level will  
be in the maximum, 100.0 %. 
 
13. Automatically, the display shows the main menu. 
Pressing ESC the unit returns to read state. 
Pressing (+) we can enter in output adjustment 
menu and simulation mode.
