Data Transfer to a Computer
To view the collected data on a computer, remove the SD card and insert it in an SD card
reader on the computer. Or, use the supplied USB cable and connect the instrument to the USB
host (computer). The user can only view/manipulate data on a computer via the USB
connection, or with the removable SD card. Data cannot be viewed after it is saved on the F-
900.
Once the instrument is connected to the computer via USB cable, it is strongly recommended
that the user copy and re-save the files and images to the hard drive of the computer. The
computer application used to view the files can also be used to re-save them. It is
recommended that the user does not work from the original file on the SD card after the
measurement has been made, because if any changes are made to the original file, it can break
the alignment of the file causing error and data loss.
In order to keep the file system in sync, perform any editing or further calculations on the copied
file saved to the computer hard drive.
Do not edit the files directly on the SD card!
Do not connect the USB cable to the instrument and the computer while performing
measurements. If the user tries to operate the instrument through the computer, the files are
subject to becoming out of sync, breaking alignment and causing errors in the files. This can
also lead to problems with saving data.
If an error occurs in a specific data file, it can be deleted and created again. Go to the File Menu
on the instrument; clear the file where the error has occurred. If the file has been transferred to
the computer, delete it on the computer also. Once the corrupted files have been deleted, create
the file again (if it has been properly cleared, the same file name can be used) and re-take the
measurement.
Data Files
Open the data files saved on the SD card on the computer using Microsoft Excel or Notepad.
The figure below is an example data spreadsheet. Data values included are the date and time of
the measurement, the ethylene level in ppm, the mode (monitor, measure or cleaning, offset or
GC emulation), the CO
2
and O
2
concentration, the temperature of the gas stream in degrees
Celsius, the relative humidity (RH) of the gas stream in percent, the atmospheric pressure (KPa)
and the flow rate of the gas stream in ml/min. In this example, when the CO
2
or O
2
sensors are
not being used, the concentration values are zero. For the mode, monitor indicates
measurements without PolarCept, sm_measure or sm_clean indicate PolarCept, and offset
indicates zero calibration.
