1. SPECIAL CYCLES
1.1. CUSTOM UNIT LEARNING
If the 4 units of flow are not appropriate for the application, it is possible to use a custom unit 
mode (manual).  To do this, a learning cycle must be carried out so that a custom unit value will 
correspond to a pressure drop.
To access this special cycle, select the unit Cal-Pa or Cal-Pa/s as a FAIL unit when creating a 
program.
Then the special learning cycle must be carried out. 
The first custom unit learning cycle must be carried out using the specials cycles menu so that a 
leak rate target which is different to zero can be entered. 
On these outputs we have:
¾
"Pass" and "end of cy
cle" if the target is lower than or equal to the FAIL reject level,
¾
"Fail" and "end of cy
cle
" if the target is greater than the test FAIL level.
From the main menu, enter the special cycle 
menu.
In the special cycle menu, select the 
"Custom unit learn" cycle.
