2.APPLICATION
Through serial output, the RS-485 allows communication with SITRAD software, which makes its
configurationsimpleandfast. ®
The is a temperature indicator with serial communication. It can work with up to three
sensors. Each sensor input can be configured individually through the advanced function menu, where
theusercanenableordisableeachsensorandadjusttheircalibrationoffset.Thefunctions and
