Setting Sample Smoothing

In vLog, sample smoothing controls how samples in a logger file are interpreted

when they are inserted into a graph, allowing you to dampen the effects of

‘noise’ in Logger files.

Sample smoothing is the minimum change in input signal required to cause a

change in displayed channel values, and is defined in raw analog-to-digital con-

verter counts.

vLog allows you to set two different sample smoothing values: one for thermo-

couple channels, the other for other channel types.

Note: Sample smoothing only affects how samples are interpreted and pre-

sented in graphs and reports; the data in the loggers and the logger files

is not affected by any settings related to sample smoothing.
