T_Pyro
Measured
temperature value
of pyrometer
-
The unit depends on the value of bit 0 in
register 1. If this bit is set, the value is the
equivalent temperature of a blackbody
multiplied by 10. If this bit is not set, the raw
pyrometer measurements are displayed.
Register 120: The function of the values depends on the type of current source that is used.

Wenn bei bitcodierten Registern ein Wert steht, der nicht in der Liste aufgeführt ist, bedeutet dies,
dass mehrere Fehler gemeinsam auftreten. Wert 160 in Register 120 beudeutet beispielsweise,
dass die Fehler CURRENT LIMIT und CURRENTSOURCE auftreten.
