Time Conductivity Endpoint(s) Analysis stops...
✔ ✔ after reaching the first criterion (conductivity or
endpoint). If the conductivity entered has been
reached, there is no further measuring until the
induction/stability time (endpoint) has been
reached.

Actions at end of determinations...
Shut off heater
on | off (Default value: off)
Automatic deactivation of the heating at the end of the determination.
Shut off gas flow
on | off (Default value: off)
Automatic deactivation of the gas flow at the end of the determination.
Caution
If the gas flow is automatically switched off, the reaction vessels must
be removed from the instrument within 30 to 60 min after the end of
the determination. If the vessels are not removed, a vacuum could
develop over the course of time, which would thus result in back suc-
tion of the measuring solution into the hot reaction vessel.
4.5.2.2 "Evaluation" tab
These settings serve for automatic evaluation of the curve. After finishing
the measurement, curves can also be reevaluated in the database (see
Chapter 4.7.3, page 112).
