In this mode, Schilling tests using the standard commercial kits Mallinckrodt - Bracco and Dicopac have
been programmed into the system. Before use, the operator should go to the Procedure Definition
Window, select the kit style used in the facility, and set-up or verify that the counting time, correction
factor and sample volumes are correct for the procedure.
For the Schilling Kits, the manufacturers recommend using a 4-ml sample volume with a correction factor
of 100 and a counting time of 600 seconds. This means that the standard, the sample and lab background
will all be counted for 600 seconds each (the correction factor deals with the standard). When the correct
parameters have been input into the kit procedure window, click on <Close>.
