50 Hz
It is recommended to select the same frequency (50 Hz or 60 Hz) as the power supply frequency in the region
where the instrument is being used.
When using the U8550 to U8553 modules and LR8530 to LR8533 modules, power supply noise can be
rejected by using the data refresh interval setting.
See "Measurement module data refresh intervals" (p. 2 2).
Configure the low-pass filter for Strain Units (U8554, LR8534) since the power supply frequency filter function
is not available for those modules.
See "Measuring strain" (p. 3 6).
