9.1 Setting the sampling time at the PA 83
On delivery the pyrometer is parameterized on a discontinuous pouring stream. If the pouring
times are < 5 seconds the measuring time needs to be adapted.
The time delay (time after detection of the pouring stream up to the start of the measurement)
and the measurement time must be less than the minimum pouring time.

If the time delay [T . D EL] must also be adjusted, proceed as described above. In this case the
parameter [T . D EL] must be selected and changed accordingly.
9.2 Setting the sampling time at the PA 80/81
The pyrometer is parameterized for continuous measurement on liquid metals.
The measuring time is set to 15 s in the delivery state. After the measuring time has expired, the
measured temperature is shown on the display or the analogue output. Afterwards, the measur-
ing time restarts automatically after the dead time has elapsed.
