displayed on the VI analysis. The VI Matching function is always indi-
cated on the VISCPRO

status bar, whether or not a VI domain (viscom-

eter 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

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 unsuccessful
samples (samples with no flow time and a displayed kinematic viscosity of
“0”). If one of the samples ran successfully at one temperature but not at
the other, the good sample can still be used for VI matching 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.
