Example: The figure below is based on the condition of set values as P1 = 40 [kPa] and P2 = 20 [kPa].
Note 3) Hysteresis mode: When the values of P1 and P2 are the same or when |P1| > |P2| within 3 digits, the hysteresis will be automatically 3 digits for the set value of P1. Window comparator mode: The hysteresis is 3 digits, so separate P1 from P2 by 7 digits or more and set them. 1 digit is the minimum pressure display unit. (See the table above.)
