8 Maintenance
8.1 Service cable
Cable AC3006 is used to connect the HF5 to a USB port of a PC running the ROTRONIC HW4 software. Prior
to connecting the HF5 to a USB port you must install the ROTRONIC USB driver on the PC (available from
the HW4 CD or from www.rotronic-humidity.com). For instructions see the HW4 manual E-M-HW4v3-Main.
8.2 Location of the service connector (mini USB type)
WARNING: the service connector is a UART interface with a mini-USB connector type. Do not connect the
service connector directly to the USB port of a PC or hub.
The service connector can be accessed without opening the enclosure after removing the small red sealing
cover.
8.3 Periodic calibration check of the probe
Both the Pt 100 RTD temperature sensor used in the probe and associated electronics are very stable
and should not require any calibration after the initial factory adjustment.
Long term stability of the ROTRONIC Hygromer humidity sensor is typically better than 1 %RH per year.
For maximum accuracy, calibration of the probe should be verified every 6 to 12 months. Applications
where the probe is exposed to significant pollution may require more frequent verifications.
Note: the HygroClip 2 probe cannot be adjusted when connected to the HF52 transmitter
HF32
