8.4 Cleaning or replacing the dust filter
Depending on the conditions of measurement, the filter should be checked from time to time. Corroded,
discolored or clogged filters should be replaced.
•
If the probe has a removable cartridge, simply replace the cartridge (leave the metal base on the probe).
• If the probe has a plastic slotted cap with a built-in filter element follow these instructions:
1) Unscrew the filter from the probe and pull it straight away, in the alignment of the probe, so as not the
catch the humidity and temperature sensors.
2) Before putting on a new dust filter, check the alignment of both sensors with the probe. The wires that
connect the sensors to the probe are very thin and bend easily. If necessary, correct the alignment by
tapping the sensor very gently with a smooth object such as a small plastic rod. Do not use sharp pliers or
tweezers as this could puncture the sensor and do not pull hard on the sensor.
8.5 Validation of the output signals transmission
If so desired, transmission of the output signals can be validated by using the simulator function. The HW4
software is required to enable and configure this function. When this function is enabled the HF63 or HF65
generates fixed digital and / or analog signals as specified by the user. For instructions see document

9 Firmware updates
Firmware updates will be available on the ROTRONIC website for downloading. Firmware files are given a
name that shows both to which device the file applies and the version number of the firmware. All firmware
files have the extension HEX.
Procedure for updating the firmware:
• Use cable AC3006 to connect the service connector to a USB port of a PC with the ROTRONIC HW4
software installed. Note that the ROTRONIC USB driver must be installed on the PC as explained in
the HW4 manual E-M-HW4v2-Main. In the case of the HF65, a connection with the PC can be
established via the USB (ROTRONIC USB driver) or Ethernet interface.
• Copy the firmware update file from the ROTRONIC website to the PC.
• Start HW4 software on the PC and search for the HF63 or HF65 (HW4 Main Menu Bar > Devices
and Groups > Search for USB Masters).
• After finding the HF6, expand the device tree to all available functions. Select Device Manager.
In the Device Manager menu bar select Tools > Firmware Update. For instructions see document
