Could you please explain a fine valve and a gross valve? thanks
I Have Apex Methode 17. I Have question to you. I set Delta H with coarse valve to get 25 mmH20 delta H. But what is the function of fine valve. If i use fine valve, would it effect to number of Delta H (which I I Set 25 mmH20 before)?
