Turning off the VI Matcher
The VI Matcher essentially function as a separate instrument and is
indicated as such on the VISCPRO
® Status Bar. If you wish to terminate
VI matching, you will need to delete any VI domain(s) using the Delete
button from the General Configuration window. When no domains are
defined, the VI Matcher does not function.
Handling errors
VISCPRO ® errors The CAV instrument software returns three types of errors during opera-
tion: bath errors, fatal errors and tray errors. Bath and tray errors are
sample/tray specific, and may affect test results for a given sample. Such
results will be indicated as invalid. Fatal errors may be hardware-related,
and can produce a FAULT condition (see Chapter 5, Handling fault
conditions).
