The thermal spotmeter can trigger events based on the measured temperature. The measurement area covers the four pixels at the center of the image.
The temperature of objects in the image as determined by the thermal sensors is influenced mostly by the following factors:
Surface properties and object color
Distance from the sensor to the objects
Properties of the atmosphere between the sensor and the objects
This means that the sensor can deliver different temperature values depending on the distance to the object and the current
scene. In order to define events that are based on temperature trigger values, you first need to determine the current temperature
values measured in the scene. To do so, you can use the variables $(SEN.TSR.CELSIUS) and $(SEN.TSR.FAHRENHEIT) for the right sensor or $(SEN.TSL.CELSIUS) and $(SEN.TSL.FAHRENHEIT) for the left sensor. The determined values can then be used to set the trigger value defined below.
In order to exactly point the sensor to the object you want to measure, the camera can display crosshairs in the live image. The circle at the center of the crosshairs shows the four pixels that are used for measuring.
Show the temperatures either in degrees Centigrade (°C) or Fahrenheit (°F).
Enter the temperature value that is used to trigger an event when it exceeds or when it drops below the value (depending on the setting of the Comparison parameter, see below).
Select between triggering the event when it exceeds or when it drops below the specified trigger value.
Higher than: Triggers an event if the temperature in the measurement area is higher than the trigger value.
Lower than: Triggers an event if the temperature in the measurement area is lower than the trigger value.
Define how often the event is to be triggered:
First: The event is triggered only once, i.e., when the condition is first detected.
Every: The event is triggered every time as long as the condition is true.
Cliquez sur le bouton Définirpour activer les paramètres et les sauvegarder jusqu'au prochain démarrage de la caméra.
Cliquez sur le bouton Config. usine pour réinitialiser tous les paramètres de cette boîte de dialogue selon la configuration initiale (ce bouton n'est peut-être pas disponible pour toutes les boîtes de dialogue).
Cliquez sur le bouton Restaurer pour annuler les dernières modifications qui n'ont pas été enregistrées définitivement dans la caméra.
Cliquer sur le bouton Fermer pour fermer la boîte de dialogue. Lors de la fermeture de la boîte de dialogue, le système vérifie si les paramètres ont été modifiés. Si tel est le cas, le programme vous demande si vous souhaitez enregistrer ou non de façon permanente la configuration globale.
