Object Temp.: The display shows the current temperature of the measured object.
Ambient Temp.: The display shows the current internal temperature of the sensor.
Emissivity: Changes the emissivity value. The emissivity is a calculated ratio of infrared
energy emitted by an object to the energy emitted by a blackbody at the same
temperature (a perfect radiator has an emissivity of 1.00). For information
on determining an unknown emissivity and for sample emissivities, see
section 12.2 Typical Emissivity Values, page 84.
Transmission: Changes the transmission value when using protective windows. For
example, if a protective window is used with the sensor, set the transmission
to the appropriate value.
Focus: Changes the focus length of the sensor optics.
Laser/Video: Switches the laser or the video (if available) on or off. With the setting <TRG>
the laser can also be switched on/off via the external input.
Average: Parameter given in seconds. Once Average is set above 0.0, it automatically
activates. Note that other hold functions (like Peak Hold or Valley Hold)
cannot be used concurrently. The default value is 0.0.
For further information see section 7.3.1 Averaging, page 37.
Peak Hold: Parameter given in seconds. Once Peak Hold is set above 0.0, it
automatically activates. Note that other hold functions (like Valley Hold or
Averaging) cannot be used concurrently. The default value is 0.0.
For further information see section 7.3.2 Peak Hold, page 38.
Valley Hold: Parameter given in seconds. Once Valley Hold is set above 0.0, it
automatically activates. Note that other hold functions (like Peak Hold or
Averaging) cannot be used concurrently. The default value is 0.0.
For further information see section 7.3.4 Valley Hold, page 41.
Low mA: Defines the temperature for the low current output value (0 or 4 mA).
High mA: Defines the temperature for the high current output value (20 mA).
Multidrop Addr.: Defines the address of a sensor in a network. Each sensor in a network must
have a unique address. “--“ means a standalone unit with address 0.
Baud Rate: Defines the baud rate of a sensor. Each sensor in a multidrop network must
be set to the same baud rate.
Temp. Unit: The temperature display can be set to °C , °K or °F. Note that this setting
influences the RS485 output for both object and ambient temperature. The
default value is °C.
Com Mode: Selects the desired digital communication mode for the sensor, either 2-Wire
or 4-Wire.
