NOTES
The software allows the operator to manually change the constants if neces-
sary to more closely match the known viscosities of the standards.
A separate calibration must be performed for each temperature at which
samples will be tested.
Calibration procedure
1. Assemble a group of
CANNON
®
standard oils with known kine-
matic viscosities for calibration. Use at least two different standards
for each bulb. Refer to the following table when choosing the appro-
priate standards.

2. Complete sample ID data entry for each standard.
3. After entering each sample ID, click on the highlighted ID entry using
the RIGHT mouse button (or press
5). Then select
Verify Known
KV
from the popup window. The
Viscosity Action
window will
appear.
4. Enter the viscosity (in centistokes) for each sample from the standard
bottle, along with other desired configuration settings; then click
OK
.
NOTE
If a check standard viscosity has NOT been entered (or if the default
viscosity value of 1.000 has not been accepted by the user), a yellow arrow
(current sample) or red circle caution symbol will appear to the left of the
sample ID:
