11.4 Device Setup
11.4.1 Temperature Calculation
U=C unit for the temperature value
E=0.950 Emissivity setting (Caution: according to the settings
for “ES”, see section 11.4.2
Emissivity Setting and
Alarm Setpoints on page 70.)
XG=1.000 Setting for transmission
For the calculation of the temperature value, it is possible to set an
offset (relative number to be added to the temperature value), and a
gain value.
DG=1.0000
Gain adjustment for the temperature signal
DO=0 Offset adjustment for the temperature signal
In case 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
11.4.2 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 – FTC 3)
?CE asks for the emissivity value that is actually used for
temperature calculation
