7-7-23 Electromagnetic Interference (EMI) Troubleshooting
7-7-23-1 Prevention/abatement
For EMI rules and details, see "EMI Limitations" on page 2-4.
7-7-23-2 Different power outlet
Connect the LOGIQ™ S8 to another power outlet and check to see if the noise changes or disappears.
NOTE: Image artifacts can occur if, at any time within the facility, the ground from the main facility's incoming
power source to the LOGIQ™ S8 is only a conduit.
See "Minimal floor plan suggestions" on page 2-9.
7-7-23-3 Different system
Try another LOGIQ™ S8 at the same location and look for the same noise. If the noise is present on
the new system too, the noise is most likely from an external source/equipment.
7-7-23-4 Different location
Move the LOGIQ™ S8 to another location and check to see if the noise changes or disappears. This
may help to locate an external noise source.
Try to move the LOGIQ™ S8 to:
• another location inside the room
• another room
• another floor
7-7-23-5 Disconnect external cables
Disconnect all external cables (network, all unused probes, ECG leads, etc.) and check to see if the
noise disappears.
