| 1. A method of equilibrating corresponding vacuum line parameters in an electronic device manufacturing system including a
pump comprising:
acquiring information related to a parameter of a first vacuum line and information related to a parameter of a second vacuum
line, wherein the first and second vacuum lines are fluidically separate;
comparing the information related to the parameter of the first vacuum line with the information related to the parameter
of the second vacuum line; and
adjusting at least one parameter of the pump such that corresponding parameters of the first and second vacuum lines are equilibrated.
