Using the ROTRONIC HW4 software, the HF7 can be configured by the user to calculate either the dew point or the frost point. Analog output signals With the ROTRONIC HW4 software any of the two analog output signals can be made to correspond to one of the following: •... -
Page 6: Service Connector
The service connector is a UART digital interface (Universal Asynchronous Receiver Transmitter) with a mini- USB type connector. This allows connecting the HF7 either to a PC running the ROTRONIC HW4 software or to a probe input of another instrument that is compatible with the HygroClipAdvanced 2 (HC2A) probes. In both cases a service cable is required. -
