WebCheck the “vacuum” reading. This is the foreline pressure (the pressure through the rough pump). The final reading depends on 3 variables: the condition of your oil diffusion pump (for those systems with such a pump), the condition of your rough pump and the flow entering the source. Typical values are 10-80 mtorr. The important thing is to ... WebCheck the level of the oil in the foreline pump. If necessary, add foreline pump oil or replace the oil. Also check the condition (color) of the oil. The foreline pump oil gradually becomes less effective as it is subjected to heat, air, water, solvents, and samples. One symptom is a gradual darkening of the oil. Foreline hose is constricted
