“Analog” Vacuum Level Bar Graph
The Vacuum Level Bar Graph has two modes:
Evacuation Progress Indicator
When the pressure is above 25,000 microns (when the display shows ), the Bar Graph indicates
evacuation progress. The bars progressively drop as the pressure drops between ATM and 25,000
microns.
Vacuum Level Indicator
Below 25,000 microns, the Bar Graph allows for a quick visual determination of the vacuum level
achieved. Each bar corresponds to a vacuum pressure range depending on units according to the
following table:

Alternate Numeric Display
The BluVac+ LTE has an Alternate Numeric Display that can indicate Vacuum Leak Rate.
The Vacuum Leak Rate Indicator displays the rate of change of vacuum per second or per minute in
the selected units when the indicator is illuminated. The reading is positive for increasing
pressure and negative for decreasing pressure. The Leak Rate Indicator is useful for determining the
size of a vacuum leak, if one exists, or the presence of moisture or outgassing. Under high-pressure
conditions ( ), the leak rate indicator shows .
Press and hold the key while the indicator is showing to switch between per second
and per minute, as indicated by and on the display.
Swivel Hook
The BluVac+ LTE’s removable stainless steel swivel hook enables hanging of the gauge and will
allow it to swivel freely in any direction. The gauge may be operated with or without the hook
attached. When fastening the hook to the gauge, turn it finger tight only. Use of a tool to tighten the
hook may result in damage to the BluVac+ LTE case.
