Reading the Vacuum display:
The level of vacuum is shown on the display with (5) five vacuum bars. During
evacuation, the vacuum bars will increase from (1) one bar, no vacuum, to a
maximum of (5) five bars, high vacuum. The more bars displayed, the higher
the vacuum. For a more detailed vacuum level see vacuum specifications.
Note: The DIGIMON must be powered ON before connecting the hoses and
switching on the vacuum pump. If this is not in the correct order the vacuum
display will not show the correct vacuum level.
The end-vacuum depends on the capacity of the vacuum pump and the current
atmospheric pressure.
For an exact level of vacuum and for vacuum leak checking it is recommended
to use a separate micron vacuum gauge like the VG-64 or the Absolute-Vacuum
Gauge 19621(see REFCO catalog).

4. Press and hold ENTER and LIGHT button at the same time.
