Limits
Hysteresis
Solvent Library
Actions after stop
In this menu, limits for the target value can be set.
With the "Hysteresis" option, the switching frequency and control
accuracy can be influenced when in a steady state. The hysteresis
value determines the upper and lower limits of the target value
and therefore the closing and opening of the pump and valve
(only for two-position control).
Automatic: Hysteresis is always 10 % of the actual pressure.
Manual: Manual value specification of hysteresis.
NOTICE
In the "solvent library", the most common solvents are assigned a
function to determine the steam temperature at the set pressure
and vice versa. This provides assistance when setting these para-
meters in manual mode, for example, evaporation processes with
a rotary evaporator.
This menu allows the user to define actions that should be perfor-
med when a test has ended.
Limits which are too narrow shor-
ten the service life of the devices.
