Setting Sample Smoothing
In Spectrum, sample smoothing controls how samples in a logger file are inter-
preted 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.
Spectrum allows you to set two different sample smoothing values: one for
thermocouple 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.
