the system is powered ON and once a high enough level has been
achieved then a complex analysis takes place to determine the
correct spectrum position. This analysis results in an error
measurement that the system uses internally to correct these
effects. Note that this process is completely independent of the
user. Typical Automatic Stabilization takes 5-10 minutes
depending on local conditions.
Once the system is fully stabilized a new icon appears
on the display above the Battery icon to show the analysis is
complete
– see figure. The RS-125 can continue to be used in
the SURVEY mode while this fully automatic process is carried out
in the background.
If the system is
NOT
stabilized and the user attempts an
Assay
,
an error message appears and
the unit beeps 3 times
.
If the
user ignores this warning, the Assay continues
– note that
under these conditions the quality of the Assay data is questionable as system Stabilization is incorrect
so the data could be roughly
OK
if stab is close but really bad data if Stab is significantly in error. The
stab status is shown on the data retrieved to the PC for data verification.
In previous software versions, Stabilization was inhibited during Assay to minimize data errors.
However if users are taking repeated Assays this means that Stabilization will be suspended for a long
period of time and during this period the system could drift causing significant data errors.
To prevent this happening in Ver. 5v95 the Stabilization accumulation of data is NOT interrupted by
the Assay process.
In fact an auto correction is implemented so that if at the end of Assay a Gain correction is required,
the system automatically computes the potential Gain error and corrects the data to minimize system
errors.
In addition the unit beeps every time it stabilizes as a reminder to the user that all is well. This can be
inhibited if judged to be a problem
– contact RSI. See
Appendix Z
for Contact Information.
2.9 ACTION
The RS-125 only has one
BUTTON
as noted above. To achieve
the required system functions
CLICK
(short) and a Menu
appears. The user navigates up and down this menu using
CLICK
(short) and the highlighting moves with the selection.
Once the selection is made, hold the
Button
until the
background changes from Dark to Light (typically 2-3 secs) then
release the Button to make the selection.
Selections:
a)
Assay
– activates the ASSAY capability of the system
(see
Section 2.10
below)
b)
Reacquire bg
– rests system background
(see
Section 2.11
below)
c)
Start recording
– activates the RECORDING capability of the system
(see
Section 2.12
below)
d)
Configuration
– permits parameter changes (in firmware versions before ver. 5.19, parameter
selection was accessed on power up but v5.19 has made setup easier) -
(see
Chapter 3.0
below)
e)
Continue survey
– this selection returns to the previous SURVEY display with NO change in
background setup levels.
