Low Temperature Operation The eVac Pro can operate accurately at temperatures as low as 10˚F (-12˚C). While operating below freezing (32˚F/0˚C), the display update rate will slow from 3.5 readings every second to one reading every two seconds. For satisfactory battery life at low temperatures, a 9V Lithium battery is recommended. -
Page 15: Frequently Asked Questions
Q. Can I use the eVac Pro to check the proper operation of my vacuum pump? Yes. Attach the eVac Pro directly to the pump with a short hose or coupler. Turn the pump on, open the blank-off valve, and close the ballast. A good pump with clean and dry oil will typically pull very quickly to less than 100 microns (generally around 25 microns for a two-stage pump). - Page 16 Pressure within the allowed Rise Time Target Time Period.
