Lum-Ex Correction
Lum-Ex Correction provides a means of distinguishing between counts of actual radioactive
disintegrations within the sample and other light-producing events, such as
chemiluminescence. The % of the total count rate that is luminescence is always printed as %
Lum-Ex on the printout whether it is selected On or Off. When Lum-Ex Correction is
selected On, the luminescence counts in the counting window of each isotope are subtracted.
To change the setting, highlight “Quench/Lum-Ex/2Phase” and press SELECT. The menu
shown in Figure 4.8 is displayed. Highlight “Lum-Ex Correction” (if installed) and choose
NO
(Off) or YES (On). If no other changes are desired, press PREVIOUS MENU to display the
