When selecting ”Graphic” the display shows a pressure vs. time curve.
The timeline in the diagram adapts automatically to the process time.

Press the selection knob twice to return to the standard display.
+
Switch on (the higher switching value): If the pressure exceeds this
pressure, pumping down starts again.
The ”Switch on” pressure is adjustable in the range of 2-795 Torr (2-
1060 mbar) (at the least 1 Torr (mbar) higher than the ”Set vacuum”).
In the event of a sudden high-pressure spike, pumping starts again
even if the ”Switch on” pressure has not been reached (pressure in-
crease control).
+
Delay: If the vacuum is below ”Set vacuum” for longer than the ”Delay”
time, the pump is stopped. Pumping starts again in the event of a rapid
pressure increase or if the ”Switch on” level is exceeded.
The ”Delay” is adjustable in a range of 1-300 minutes or can be set to
”Off” (”Off” means that the pump stops immediately when the pressure
drops below ”Set vacuum”.).
