2. Before using this unit
Temperature output terminal
The temperature output signals for the Outlet (outlet temperature) and the Inlet (inlet temperature) are
4-20mA for the measure temperature of 40-320
°
C.
[Current output of 4-20mA:
Measured temperature of 40-320
°
C]
Conversion formula: Current output I (mA) = (0.05x measured temperature T(

When you connecting to the voltage input of the recorder, connect a fixed resistor (shunt resistor)
of 600
Ω
or lower to the voltage input of the recorder.
