transformer and the use of a noise filter are recommended.
Make sure that the noise filter is installed to a place such as a panel that is properly grounded. The
wiring between the noise filter output terminal and the instrument power supply terminal should be
made as short as possible. None of fuses or switches should be installed to the wiring on the noise
filter output side because the filter effect will be degraded by such a installation.
