Calculation rule
• When you set a negative differential value
∆, the On
threshold ≥ Off threshold, and:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax ≤ Off.
See the timing diagram A.
• When you set a positive differential value
∆, the On
threshold < the Off threshold, and Q = 1, if:
On ≤ actual value Ax < Off.
See the timing diagram B.
