19 V-850/855 Operation Manual, Version E
4.2.7 LabVac mode
The LabVac mode serves to control the pump within a laboratory vacuum system.
The pump operation is switched off when the vacuum has reached the lowest possible value and is
switched on again when the pressure increases by a preset value (hysteresis [dP]). The pump opera-
tion is also switched on, as soon as a load is present in the vacuum system.
When the menu button CONT. is pressed the pump operates in Continuous mode to obtain a vacuum
as low as possible independent of the connected load.
