The following parameters for Block A or Block B can be altered live:
Stop criteria
Time
Time up to automatic termination of the deter-
mination.
Range:
0.1...100 h
Conductivity
Conductivity limit value. When this value is
reached the determination is automatically ter-
minated.
Range:
1...400
µµS/cm
Endpoint(s)

when each active channel has reached all end-
points
.
Shut off at end of determinations
Heater
Automatically switches off the heating at the
end of the determination.
Gas flow
Automatically switches off the gas flow at the
end of the determination.
If the gas flow is automatically switched off,
the reaction vessels must be removed
from the PVC Thermomat within 1 h after the
end of the determination. If the reaction
vessels are not removed, a vacuum is gener-
ated in the course of the time by condensa-
tion of the further produced HCl in condensed
water vapor from the measuring vessel and
the measuring solution is siphoned back into
the hot reaction vessel.
Stop determinations
Determinations are normally terminated automatically when the stop
criteria defined in the method have been achieved. Running determina-
tions can also be stopped manually be clicking on the following buttons
in the operating area of the
763 PVC THERMOMAT CONTROL
window:
