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.
Note: The DIGIMON must stay powered ON while pulling a vacuum. If the DI-
GIMON is powered OFF while pulling a vacuum, 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).
Reset
For best results it is recommended to reset/zero the manifold periodically every
40 to 50 hours.
1. Disconnect any hoses.
2. Open low side (blue) and high side (red) valves.
3. Turn on the manifold by pressing the ON / OFF button for 1 second.
4. Press and hold ENTER and LIGHT button at the same time.
5. When the word “ZEro” is shown on the display release ENTER and LIGHT
buttons.
