Power Noise Filter
is the other feature of the Measurements
tab. The AC electrical power in your office or home can add a subtle
amount of noise to the data logger sensor measurements. The log-
ger Power Noise Filter setting is designed to eliminate this electrical
noise that comes from the AC power distribution system. You should
set the value of the Power Noise Filter to match the frequency of the
power cycle where you live. In North America and most of Asia,
this is 60 Hz (the default value). In most of Europe the electrical
frequency is 50 Hz. This feature only needs to be set once, as the
program automatically updates each connected device filter.
