ECOTEST VIRTUOSO RKG-14 Operating Manual page 45

There are three ways to complete the search for cesium radioisotopes in
food:
1 Automatic completion upon achieving measurement progress equal to
100 %;
2 Forced completion after you tap the "Stop" button (the option of activity
evaluation will become available, provided that you have currently gathered
sufficient information and the progress equals to more than 50%);
3 Search interruption upon achieving maximum test time, which is 6 hours
(the "Continue search button" will be disabled).
Important: It is recommended to wait for automatic completion when
measurement progress becomes equal to 100%. In the case of forced
completion, you should consider that the specific activity determination
becomes more accurate in the process of testing. You will get more reliable
results only if you continue measurement.
After completing the search for cesium isotopes, the window of the basic
mode will look as shown in Figure 2.24 (a) if cesium isotopes in a tested food
product are absent or as in Figure 2.24 (b) if cesium radioisotopes are present.
In case of forced completion of measurement with less than 50% of
measurement progress, the activity evaluation option will be disabled (Figure 2.24
(a)). In case of measurement completion with the progress more than 50% but less
than 100%, approximate value of activity is available. For more accurate value,
please continue the search until its auto-completion with 100% of measurement
progress. (Figure 2.24 (b)). If you need to get as accurate result as possible,
continue testing even after achieving 100% of measurement progress. Touch the
"Continue search" button to continue the search. Maximum testing time makes 6
hours. Then the search is automatically stopped and no further testing is possible
(the "Continue search" button is disabled).
