Setting Up User Programs
Editing A User Program
To select an item to include on the printout, highlight the desired item and choose Yes. The
order of the items is predetermined and cannot be changed. All sample data are printed on
one line, with print size automatically set to 80, 96 or 132 characters per line, as required. If
the characters per line exceeds 132 characters, then one line of data per isotope is printed.
Collecting Spectral Data
Both sample and Compton spectral data may be obtained from the multi-channel analyzer
(MCA) either as a routine part of a general counting program or by itself (no other type of
data is collected). If spectral data are needed for only part of a particular sample set, then it is
convenient to divide the set into
two groups: those requiring spectral data and those which do
not. Set up
two User Programs with identical counting programs. Under one User Program set
up Edit Format with Spectral Data. This permits the original sample set to be counted under
identical conditions as the set counted to obtain Spectral Data only.
