3.9 Suppressing Noise (Enable Digital Filtering)
100
Electrical noise mixed with input signals can be removed by digital filtering.
(This setting is valid for the LR8510, LR8511 and LR8515.)
LR8510, LR8511
When the recording interval is from 500 ms to 1 h, 50/60 Hz power supply noise can be
rejected.
It is recommended to set the filter to either 50 Hz or 60 Hz based on the power frequency
in your area. Doing so will increase the difference in measurement times between mea-
surement unit channels. Set the filter to OFF if you wish to minimize the difference in
measurement times between channels.
See:
"Cut-off frequency" (p .297)
LR8515
The filter can reject 50/60 Hz power supply noise when using a recording interval of at
least 100 ms. When set to OFF, operation is the same as when set to 60 Hz.
Make these settings on the [Setting] screen.
