CT Profiles
Improve the accuracy of the 928A by installing CT
profile (CT Characterization File) for the specific CT
probes you use. In Mlink software, this characteriza-
tion file is called a Profile. The 928A can store up
to 5 separate profiles for different probes or different
characterizations for the same probe.
