Output Processing
The sensor has a response time of 125 ms. If this is too fast, or to minimize the effects of temperature
fluctuations or noise on the measurement, the averaging period can be set between 0 and 60 seconds.
Emissivity Setting
Enter the desired emissivity setting here. Emissivity can be set between 0.2 and 1.0.
For an accurate temperature reading, the sensor’s emissivity setting should match the actual emissivity of
the target surface.
Non-reflective non-metals, such as rubber, foods, thick plastics, organic materials and painted surfaces,
generally have a high emissivity, around 0.95. This is the default setting.
Bare, clean metal surfaces can have a very low emissivity, and are often difficult to measure accurately. If
possible, a measurable area of the surface should be painted or coated to reduce reflections and increase
the emissivity.
For more information about emissivity, contact Omega.
Reflected Energy Compensation
In most applications, the target surface has the same surroundings as the sensor (for example, it is in the
same room). In this case, Reflected Energy Compensation should remain disabled for an accurate
measurement.
However, if the sensor is positioned outside an oven or furnace, with the target surface inside, the reflection
of the hot furnace interior can affect the measurement. In this case, Reflected Energy Compensation should
be enabled, and set to the temperature inside the oven or furnace.
