If the ambient temperature is not requested by the internal head temperature, you must set the
ambient temperature values, as follows:
A=250.0 Ambient temperature (example)
AC=1 Control ambient background temp. compensation
18.4.2 Temperature Pre-Processing
The samples from the AD converter (energy values) can be processed before temperature calculation.
The corresponding filter command is <FF>.
18.4.3 Emissivity Setting and Alarm Set points
The device allows three choices for the emissivity setting and two for the alarm output setting.
ES Selection of the emissivity setting.
ES=1 Emissivity set by a constant number according to the „E“ command
ES=E Emissivity set by a voltage on FTC1 (analog input)
ES=D Emissivity set by the entries in a table (selected by digital inputs FTC1 – FTC3)
?CE asks for the emissivity value that is actually used for temperature calculation
There are eight entries possible for emissivity setting ① and a related set point (threshold) ② . To be
able to write or read these values, use the following commands:
EP=2 set pointer for table entry, e.g. to line 2 ③
EV=0.600 set the emissivity value for line 2 to 0.600 ④
SV=220.0 set the set point (threshold) for line 2 to 220.0 ⑤
Figure 83: Table for Emissivity and Set Points
To activate these emissivity settings, you need to have the 3 external inputs (FTC) connected.
According to the digital combination on the FTC wires, one of the table entries will be activated, see
section 7.2
Emissivity (digital) , page 41.
