with matching Sample IDs. If samples with an identical Sample ID have
been tested on a low temperature tube and a high temperature tube within
an 8-hour time span, the VI for those samples can be calculated and
displayed on the VI analysis. The VI Matching function is always
indicated on the VISCPRO
® status bar, whether or not a VI domain
(viscometer tube set) has been defined.
Configuration procedure To configure the VI Matcher:
1. Load the VISCPRO ® software.
2. Log on to the system as a Manager (a password may be required) to
access the VI Matcher function, which is security-protected.
NOTE For more information on the security log-in procedure, see Security
Options, this chapter.
3. Select VI Matching—General Configuration from the Configura-
tion menu options. The General Configuration window will appear.
The VI Matcher General Configuration window
4. Click on the Allow Matching of Invalid Samples box if you wish to
permit VI matching of samples with flow times exceeding the
specified tolerance for repeatability.
NOTE The VI Matcher does not match invalid samples UNLESS the Allow
Matching ... box is checked. The VI Matcher never matches unsuccess-
ful samples (samples with no flow time and a displayed kinematic
viscosity of “0”). If one of the samples ran successfully at one tempera-
ture but not at the other, the good sample can still be used for VI match-
ing if the failed sample is rerun within the time frame selected for the VI
Matching Date Filter for the analysis.
5. Click on the ADD button to add a new VI configuration.
