Page 6: General Description
The HF3 measures relative humidity with a ROTRONIC Hygromer IN1 capacitive sensor and temperature with a Pt100 RTD. Calculated parameters Using the ROTRONIC HW4 software, the HF3 can be configured by the user to calculate either the dew point or the frost point. © 2009-2016; Rotronic AG E-M-HF3-V1_24 1.800.561.8187... -
Page 7: Analog Output Signals (Hf32 And Hf33)
Instruction Manual Page 7 of 27 Analog output signals (HF32 and HF33) HF32 and HF33: with the ROTRONIC HW4 software any of the two analog output signals can be made to correspond to one of the following: • Relative humidity •... -
Page 8: Service Connector
The service connector is a UART digital interface (Universal Asynchronous Receiver Transmitter) with a mini- USB type connector. This allows connecting the HF3 either to a PC running the ROTRONIC HW4 software or to a probe input of another instrument that is compatible with the HygroClip 2 (HC2) probes. In both cases a service cable is required. -
