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

DO=0

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

AC=1

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
