3.6 Service connector
The service connector is a UART digital interface (Universal Asynchronous Receiver Transmitter) with a mini-
USB type connector. This allows connecting the HF5 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. The service connector is used to configure the HF5 and to and update its firmware with the HW4
software.
Note: any digital output (USB, Ethernet and RS-485) offers the same functionality as the service connector.
3.7 Probe
The HF5 is compatible with all available models of HygroClip 2 probes. For detailed information on the probes
see document E-M-HC2 Probes-V1.
3.8 HW4 software version compatibility
The HF5 version 2 requires HW4 version 3.0.0 or higher for full functionality of the Device Manager function.
4 User configurable settings and functions
The HF5 ships configured as specified on the customer order. Models with analog outputs only can be
installed and used just as any conventional humidity and temperature transmitter and most users will never
need to use the HF5 configurable settings and functions. Models with a digital output generally require some
configuration by the user.
Making use of the HF5 and probe configurable settings and functions is entirely up to the user and the
appropriate settings depend on the user application. We have provided below a short description of the HF5
and probe functions and also indicated the factory default settings.
4.1 Function overview
MEASUREMENT ACCURACY AND RELIABILITY (PROBE FUNCTIONS)
AirChip 3000 Functions Description
► Humidity / temperature adjustment o 1-point or multi-point humidity calibration or adjustment
o 1-point or 2-point temperature calibration or adjustment
o Generate a time stamp for calibrations and adjustments
o Retain and view last adjustment date and adjustment values
o Generate calibration and adjustment protocols
► Automatic humidity sensor test
and optional drift compensation Tests the humidity sensor for drift caused by contaminants and
can be used to automatically apply a correction. The test is
automatically carried out at regular intervals of time. Can be
configured, enabled, or disabled
The humidity sensor status can be verified either with the HW4
software or with the instrument display (if available) and is
shown as Good, SQ-tuned (corrected for drift) or Bad (defective)
Not available when the probe is connected to a HF52
