keyword=question about ref. cell evac procedure
In the 7-page TO procedures document, the procedure for evacuating the reference cell is described as "hold down the evacuation button until it starts flashing, at which point the button will latch on and continue pumping the cell". However, I hold the button for a very long time and never saw this happen. When I let go, the pressure gauge still reads 000, and the light is still on. I'm assuming the vacuum is stable, but I would like one of the experts to check whether there is a problem or if the procedure has changed.
