ECOPROBE 5 - rs dynamics

• After the station has been measured, the operator will disconnect the tubing from the instrument (the tubing
and dust filter stay connected to the probe), remove the probe from the hole and manually clean the tip
perforation to remove the residual soil particles before moving on to the next station.
If a contamination was indicated the operator should clean the probe by blowing it out to remove all
residual gas and condensation from inside the probe. Clean air can be blown through by means of a manual
pumping device such as that used for inflating rubber mattresses. It is important not to blow into the
sampling probe with your own breath as this may cause moisture to enter the probe and may give incorrect
results.
After measuring a contaminated station, use a new set of tubing and dust filter for the next station The
operator must prepare in advance and carry sufficient spare tubing and dust filters into the field. After
completing a contaminated station, the used tubing and dust filter are stored for future cleaning. Used
tubing will usually self-clean when placed on the room heater overnight and is ready to use on the next day.
Dust filters may stay contaminated and their residual contamination must be measured before re-using in
the field.
• At the next station the operator will repeat the measuring procedure by making a hole and inserting the
probe. Wait a while before starting to measure by pressing right arrow on the instrument handle. Always
use the right arrow to start measuring the next station, because it means that the “Y” coordinate is
increased by the selected increment. The measuring cycle starts with resetting and follows the described
procedure.
4.2 REPEATING A SELECTED STATION
� If you need to re-measure a station do not use the original hole as the soil vapor conditions may have
been changed by the first effort. Always make a new hole about 30 cm away from the previous one. In the
Measuring Mode of the instrument (Window W.11.1)select the station you want to re-measure using
left/right arrow button on the instrument handle. Press the RUN button and window W.12 will be displayed.
� Select Measure from the displayed menu (Window W.12). The measurement of the station with the
displayed coordinates is repeated. The original values will stay on the screen. Both original and new
values are stored in the instrument disk and are available in the data sheet after transferring data to a
computer using ECOPROBE_VIEW software.
