Please verify the product identification label to determine which power supply option is installed on your transmitter.

  • Page 5: Probe Inputs

    The HF8 has two probe inputs. Probe input 1 is the input that is the closest to the front of the transmitter (see picture) Using the ROTRONIC HW4 software (Device Manager), each probe input can be configured to accept one of the following: HygroClip 2 humidity-temperature digital probe.

  • Page 6: Measured Parameters

    ROTRONIC HW4 software. Custom Calculations The ROTRONIC HW4 software version 3.2.0 or higher is required for setting up custom calculations and a service cable is required to connect the HF8 to a PC running the HW4 software.

  • Page 7: Real Time Clock

    All 4 analog outputs of the HF8 provide the same type of signal: 0…20 mA or 4…20 mA or 0…1V or 0…5V or 0…10V. The type of analog signal can be selected globally for all outputs after connecting the HF8 service connector to a PC running the ROTRONIC HW4 software. No adjustment is required after changing the type of output signal.

  • Page 8: Optional Display And Keypad

    The HF8 uses the RO-ASCII communications protocol. This protocol is not compatible with the protocol used by the previous generation of ROTRONIC instruments and by the HygroLog HL-NT data logger. Do not connect legacy products or the HL-NT data logger to the same RS-485 multi-drop network as the HF8 transmitter.

  • Page 9: Audible Alarm (Beeper)

    The service connector is a UART digital interface (Universal Asynchronous Receiver Transmitter) with a mini- USB type connector. This allows connecting the HF8 with a service cable to a PC running the ROTRONIC HW4 software. See “Maintenance” for the location of the service connector and for the type of service cable to be used.
