VALUE
1. Press PosiVend™ until the display shows CAL.LST XXX.
XXX can be any number from 0 to 255, and represents the most re-
cent value read from the sensor. The lower the number the greater
the sensor blockage. A number of 255 means that there is a fatal
problem with the PosiVend™ interface board. Ensure the PosiV-
end™ interface PCB is properly connected to the main controller
PCB.

operation - i.e. 51 through 254). Although this number could
go as low as 20, the PosiVend™ system will be inoperative in
this condition.
