EMI Effect on CEQ™ (2000 Series / 8000 Series) Performance and Recommended
Mitigations
Under the test conditions specified by the European normative electromagnetic
compatibility standard EN 61326-1, the CEQ instrument may exhibit temporary
degradations in performance in accordance with the table below.
Because the environmental circumstances contributing to the problem can vary,
several different mitigation techniques have been provided that should help eliminate
or reduce the interference.

receptacles. The power line to the laboratory should be
connected directly from a main power line transformer of a
power source that is known to be clear of erratic power loads,
spikes and electromagnetic interference.
Power lines used with this system must have an adequate
reserve capacity to allow for start-up loads and the additional
equipment of this system. Beckman Coulter recommends that
the normal loading not exceed 50% of the nominal capacity of
the power lines.
Effect on Performance
May cause temporary degradation
of base calling accuracy. In some
cases, significant noise will appear
in the measured results. Will
return to normal performance
once exposure is removed.
May cause temporary loss of
capillary temperature control
resulting in lower than expected
capillary temperature. Affect will
be documented in the run log. Will
return to normal performance
once exposure is removed.
May cause temporary loss of
capillary temperature control
resulting in run not being initiated
because temperature cannot
reach desired level.

Mitigation
• Re-run sample.
• Move location of the product
by several meters.
• Change the orientation of the
equipment by 90 degrees.
• Avoid using transmitters or
cellular phones within 1 meter
of the equipment.
• Review the temperatures in
the run log for any anomalies
and re-run as necessary.
• Apply mitigation techniques
above.
• Disabling the temperature
