5.4.2 Emissivity Setting (digital controlled)
The sensor’s electronics contains a table with 8 pre‐installed settings
for emissivity. To activate these emissivity settings, you need to have
the inputs FTC1, FTC2, and FTC3 connected. According to the
voltage level on the FTC inputs, one of the table entries will be
activated.
0 = Low signal (0 V)
1 = High signal (5 V)
A non‐wired input is considered as “High”!
