ECOPROBE 5 - rs dynamics

3.7 PROBE DEPTH
The depth of the hole into which the probe is inserted is noted. The value can be changed by accessing the
Enter Number Menu (Window W. 7). This note is only for information and is not used for any internal
software evaluations.
3.8 SAVE CURRENT VALUES
The measuring trace (see also “Sampling Rate” above) from PID and IR channels at any station can be saved
and displayed later on a PC using ECOPROBE_VIEW communication software. (“Save Current Values”
option is set on “YES”). The possibility of recording the progress of measurements provides an insight into the
soil conditions. Nevertheless, saving “Current values” uses disk space and this should be considered while
working with the instrument.
3.9 TEMPERATURE
Enter the ambient air temperature for the record. Default value is “99 grad” which means that no value has
been inserted. This note is only for your information and is not used for any internal software evaluations.
3.10 ANALYZERS
The next step is to select the operating mode of the PID and IR analyzers. Those analyzers which are not
actually needed for an investigation can be switched off to save battery current..
3.10.1 PID
ON/OFF
Switches the PID analytical mode ON/OFF
RANGE:
STANDARD The measuring range is from 0.1 ppm to 4000 ppm. Results are displayed in ppm or in
mg/m3 . This mode is used for general soil contamination survey.
HI-SENS Very sensitive mode. Results are displayed in ppb or in µg/m 3 .The upper limit of this mode is
100 ppm. If the measured value exceeds 100 ppm, a message “over” is displayed on the screen. HI SENS
mode is extremely sensitive and is intended for special measurements where the influence of other factors
(moisture, tubing contaminant residue etc.) is limited.
PID CALIBRATION GAS
► Opens a window with a selection of around 200 different spectral compounds that can be used for the
automatic calibration of the PID unit (see page 59 about the PID analyser).
� Use ▲/▼ to select a compound;
� ► confirms/stores the selected item and returns to the Configuration File.
Default selection is Isobutene (identical to Isobuthylene), that is used also in laboratory chromatographs.
