6. HYT Labkit
The labkit was developed as a Plug&Play tool for a fast evaluation of the HYT digital humidity sensors. The ready-to-
use system consists of a PC-adapter with an USB connecting wire, a connection adapter with plugs for all product
variants, a connection cable and an easy to operate, userfriendly WINDOWS software CD-ROM. The recording of
the measured values and the graphic presentation is carried out with the help of a PC.
The provided software PCLOG enables the online visualisation, records all measured values as graphics and stores
the measured values and data in a le. With the PCLOG software, it is easy to test the behaviour of the sensor in
an application. Additionally, the integrated PCLOG hx-computer provides the calculation and display of dew point,
absolute humidity, vapour pressure, saturated vapour pressure, enthalpy and many other meteorological parameters.
The operating manual for the software and detailed instructions for installation is available on the data medium.
Note: The Labkit does not contain any sensors. The sensors must be ordered separately.
6.1 WINDOWS-Software RECORDER
With the help of the Windows-software RECORDER, included in the labkit, the measured values (relative humidity
and temperature) can be recorded through the USB-interface and stored on the PC. The stored CSV format le is
compatible with all spreadsheet programs, through which it is possible to further process, statistically evaluate or
visualise the measured data. Additionally, the PC-software also calculates the dew point, absolute humidity, enthalpy
and vapour pressure from the measured values. The calculated parameters can also be stored.
System requirements: WIN 98, WIN 2000, WIN
XP or WIN 7, USB-Interface.
Important information: The USB should be
connected to the PC only after installing the
software. This simplies the driver installation
and enables the „Plug&Play“ feature. Windows
7 automatically installs the required drivers.
Installation: A detailed installation instruction is
provided on the CD, which automatically starts
when inserting the CD (prerequisites: Internet-
Explorer 5.0 or higher). Follow these instructions
for installation.
Manual installation: Insert the enclosed CD into
the drive and select „Run“ in the start-menu.
Then browse to select the le ‚setup.exe‘ under
the path LW:\software\RECORDER\Deu. Follow
the instructions of the installation program.
First time operation: Connect the labkit to the USB-interface. After the rst software run, go to the menu option
„settings“ and select the device type as „HYTELOG 4800“ . Then select the type of interface to be used under
„connections“ (Note: Mention the virtual COM-port specied during driver installation). The remaining settings
(Data rate, Parity, Start and Stop bit) are automatically selected and need not to be changed. If the connection is
established, the data communication appears on the window. Then select „Close“. The current settings will be
stored.
If you are not able to establish a data link between the PC and the measuring probe, please check the USB cable
connection to the PC. Further information on debugging is available under FAQ´s on the CD.
