ES=D Emissivity set by the entries in a table (selected by digital inputs FTC1 – FTC3), see
section 4.5.2
?CE asks for the emissivity value that is used for temperature calculation
There are eight entries possible for emissivity setting (1) and a related threshold value (2). To be able to
write or read these values, use the following commands:
EP=2 set pointer to line 2 (range: 0 to 7, "table entry") (3)
EV=0.600 set the emissivity value for line 2 to 0.600 (4)
SV=220.0 set the threshold value for line 2 to 220.0 (5)
Figure 38: Table Entries for Emissivities and Alarm Thresholds
To activate these emissivity settings, you need to have the 3 external inputs FTC connected. According
to the voltage level on the FTC wires, one of the table entries will be activated. See below.
0 = Low signal (active, 0 V)
1 = High signal (5 V)
A not connected input is interpreted as High signal
The table entries are controllable via the DataTemp Multidrop Software only.
