SOFTWARE FUNCTIONS

Temperature Units
Click °C or °F to switch between Celsius and Fahrenheit.
Graph
The graph is a scrolling chart of the measured temperature.
Unlocking the Software
The software settings are locked by default. To unlock the software, click the Unlock icon, enter the
password, then click the Unlock icon again.
The default password is 1234. This can be changed on the Lock/Unlock screen.
Settings
The sensor is fully configurable via the Settings menu.
Output Processing
The sensor has a response time of 125 ms. If this is too fast, or to minimise the 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.
