Parameters: adjustable on the converter’s rear side:
emissivity slope, response time, analog output 0 to 20 mA or 4 to 20 mA,
online / offline mode
additionally via interface adjustable and readable:
2-color / 1-color temperature signal, according to this emissivity slope or emissiv-
ity, temperature sub range, settings for maximum value storage, address, baud
rate, switch off limit, warning level lens contamination monitoring system.
via interface readable only:
measured value, internal temperature of the unit
Maximum value
storage: single or double storage, clear modes: time (off; 0.01 s; 0.05 s; 0.25 s; 1 s; 5 s;
