a different trip point depending on polarity will probably be due to how they have set the hysteresis
Yes, that is what is happening, but how do they do this?
When you switch the Polarity switch to a ( - ) , it will cause the output to go LOW , until you raise the (-) polarity until you cross the threshold trip point which will switch the output to a HIGH
When you switch the Polarity switch to a ( + ) , it will cause the output to go LOW , until you raise the (+) polarity until you cross the threshold trip point which will switch the output to a HIGH
The output starts off in the LOW state , until you cross the threshold
Hysteresis Type#1
the Hysteresis for the Positive and Negative Polarity have different Crossing thresholds
The Positive rising has a different rising trip point than the Negative Rising trip point
( When you Flip the Polarity switch it causes the output to switch to a LOW state)
This Hysteresis type#1 we never do a falling trip point , we only switch the polarity and so Rising Trip Point
Hysteresis just means that the rising trip point and the falling trip point are different
YES , That is what I am getting, But how do they set or what sets the rising trip point and what sets the falling trip point? they both have different voltages
Hysteresis Type#2
The Hysteresis for the Positive Rising has a different voltage than the Positive Falling trip point
