The switching thresholds are in accordance with the values for alarm 1 and 2 [►5.6 Alarms].
The alarm values are set according to the ►1.6 Factory Default Settings.
To make advanced settings (change of low- and high alarm) a digital interface (USB, RS232)
and the software is needed.
5.4 Functional Inputs (not for CT 4M)
The three functional inputs F1 – F3 can be programmed with the software only.
trigger (a 0 V level on F1 resets the hold functions)
external emissivity adjustment [0–10 V: 0 V ► ε = 0,1; 9 V ► ε = 1; 10 V ► ε = 1,1]
external compensation of ambient temperature/ the range is scalable via software
[0–10 V ► -40–900 °C / preset range: -20–200 °C]
emissivity (digital choice via table)
A non-connected input represents:
F1 = High | F2, F3 = Low.
[High level: ≥ +3 V…+36 V | Low level: ≤ +0,4 V…–36 V]
