Milwaukee MC122 ph controller question

[jbrady429]

Everyone,

What is the hysteresis on a Milwaukee MC122 ph controller like (this is the controller that a lot of people use on their calcium reactors)? For example, if I set the threshold dial at 8.3 and the function switch to "above", at what ph reading will the controller turn on the power outlet? At 8.3 or a little higher? Then, as the ph falls back below 8.3, at what ph will the controller turn off the power outlet? At 8.2 or so?

Thanks!
