If you cannot figure out how to check the vacuum on the tagger, this section will help you more. On the two pumping-devices, described in "Evacuating the Tagger", there are several meters to check the vacuum. On the pumping device near to the beamline-valve, there is an ammeter which is the most reliable to decide wether you can open the beamline-valve. But there exists also a small instrument with a analogue scale. Switch it on by turning the right button clockwise and select with the left button input number 1.

The pumping devices on the end of the tagger also have vacuum guages. There is a small white box with two orange buttons and a LED-display. Hold down the on-button until the display turns on. Read the value and compare it with the gauging list, that is glued ontop of the box. There you find the pressure corresponding to the value, that you got from the display.

When you leave the tagger area, you see at the red iron-setup, where the beamline is mounted on, meter in a orange plastic-box with a red LED-display that is always on. Follow also the instructions written on this instrument, before opening the beamline-valve.
