Edwards XDS10 Vacuum Pump

Edwards XDS10 A72601906XS vacuum pump. Powers on, runs in both speeds, LCD screen works. I feel "suction" and "discharge" from both ports. The silver "knob" with the threaded nipple also turns and the pumps seems to change function when turned. That's about all I know about the unit.
I do have refrigeration gauges but do not know how to attach them to read vacuum. If someone would like to let me know how I would be more then happy to try.
