Enter the maximum acceptable difference in measured results when using

multiple determinations (the default percent difference value is 0.35

percent and the default absolute difference value is 0.2 seconds).

Use greater

If both tolerance options are selected, the VISCPRO software will apply

both criteria unless the Use greater option is checked. If Use greater is

checked, then the software will apply the less exacting tolerance value

when calculating/evaluating test results.

The Tray Settings: Test window

The Use spread and Use mean radio button options determine the

manner in which the VISCPRO mathematically determines which sample

tests have met tolerance parameters. Testing is continued until a group of

samples meets the tolerance parameters and the rules for sample drop

time determination (see Determinations, below).

Use spread

The Use spread option compares the individual drop time values for each

test sample with the individual drop time values of the other samples. If a

sample deviates from tolerance parameters when compared with any other

sample in a grouping, the sample is eliminated from consideration.

Use mean

The Use mean option compares the individual drop time values for each

test sample with the mean (average) drop time represented by all samples

in the group. If any sample in the group deviates from the mean by a

value greater than the value specified in the tolerance parameters, the

group is eliminated from consideration.

Determinations

Select the determination option by clicking on the radio button corre-

sponding to the appropriate determination method (Always perform

maximum determinations, Use successive determinations only, or

Use any determinations).
