The N-560 is designed for use in environments in which the pulse can
be obscured by electromagnetic interference. During such
interference, measurements may seem inappropriate or the N-560
may not seem to operate correctly.
Disruption may be evidenced by erratic
readings, cessation of
operation, or other incorrect functioning. If this occurs, the site of use
should be surveyed to determine the source of this disruption, and
the following actions taken to eliminate the source:
• Turn equipment in the vicinity off and on to isolate the
of
fending equipment.
• Reorient or relocate the interfering equipment.
• Increase the separation between the interfering equipment
and this equipment.
The N-56
0 generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with these instructions,
may cause harmful interference with other devices in the vicinity.
