Sad to tell, by the time I sourced the 3 inch diam vacuum gauge and plumbed it directly to the flare outlet on the pump, to read a magnificent -0.8 bar - it was a little late to go to the dealer with it

Ho hum

Mine is getting to 70 microns (0.07 millimeters of mercury, 0.001 kiloPascals, 0.01 millibars).
Sounds like you might have a leak.

[Note to others on the list -- this is a great price on a nice pump.]

I bought the next step up (theoretically) - a 2 stage for? about $130.
Trouble is - when I obtained a vacuum gauge, it gets nowhere near zero!
