access and to download them to your computer. The PDA is equipped in standard with

memory in order to save files. The user is recommended to
store all recorded files onto external memory.
When saving files onto internal or external memory, ensure that the files are saved into
a subfolder created by the user. Do not save files directly under the root of the memory.
Pay attention to always specify a file name with a limited number of characters for
spectrums files and results files. Windows mobile operating system handles correctly
files names with up to eight characters. As spectrums or results files are indexed with a
counter number, pay attention that the file name and the index number are not more
than eight characters.
Sample measurement time can be set at Settings → Measuring. A recommended
Measuring Time for most of the application is 5 or 20 seconds. Click ok on the top right
end corner.
The longer the measurement time, the better the accuracy of the analysis results.
Measuring time depends then on your application.
The actual measurement can be initiated by pushing the START button on the PDA
display, which will begin a continuous measurement cycle (Figure 20). For example,
when using a five (5) second measurement time, results (or sample spectra) will be
updated every 5 seconds. It is also possible to initiate a continuous measurement by
selecting Measure → Continuous. The last way to start continuous measurement is to
push the upper left button on the PDA keypad (option only available with Gasmet
provided PDA). A single measurement can be trigger by going at Measure → Single.
Press the button STOP to cancel continuous measurement or push the upper right
button on the PDA keypad (option available with Gasmet provided PDA).
