CONTROLS
Note: Both vacuum functions can be manually turned on from the homepage by tapping the button
or turned on as a heating profile step parameter. The button indicator disk changes from gray
to green when turned on.
Vacuum Control
The Vacuum Control function dynamically adjusts the chamber vacuum valve to achieve
and then maintain a pressure level between room atmosphere pressure and 1 Torr. This
level can either be set by the operator using the homepage vacuum tab setpoint or
programmed as part of an automated heating profile.
Full Vacuum
The Full Vacuum function opens the oven vacuum valve all the way, supplying the
maximum draw of the pump to the oven chamber. It can pump down the chamber to
below 1 Torr and overrides the Vacuum Control function . The maximum achievable Full
Vacuum level depends in part on which pump type is installed in the oven and the rate
of outgassing from products or samples in the chamber.
Pump Start
Turns on the oven vacuum pump.
•
Pump Start must be on for the Vacuum Control or Full Vacuum functions to pump
down the chamber.

verify the system is sealed.
