Figure 24. Entering the duration of the interval.
CAUTION!
WHEN CALCULATING AN OPTIMAL INTERVAL, IT IS VITAL TO TAKE
INTO CONSIDERATION THAT THE TIME, SPENT FOR TRANSFERRING A RACK AND
FOR RACK’S DELAY UNDER A TROUGH FOR DRAINING OF LIQUID, IS NOT ADDED
TO THE VALUE OF THE INTERVAL BY DEFAULT. Before starting a new program with real
reagents, it is necessary to check that the interval has been calculated correctly by running
the program with empty racks.
The user calculates the interval’s value independently, bearing in mind the fact that
when the time of a rack processing in one reagent elapses, the station of the following
processing (next reagent) must be unoccupied. If this condition is violated (the set interval
is too small), the rack will be transferred back to the initial parking station. The performance
of a technological program for this rack will continue when the station with respective reagent
gets free.
There is also an opportunity to choose the optimal value of interval with the help of
personal computer software «FASTAINER FIRMWARE EDITOR» (
Appendix F
).
