EMC PRECAUTIONS
Conducted and Radiated Emissions
The PM100 and PM300 comply with the limits of BS EN 55022 Class A.
To ensure continued compliance, the RS232 lead supplied for PC communications must be fitted with the
ferrite at the analyzer end.
Any other RS232 or Parallel Printer leads used should have a ferrite fitted at the end of the lead closest to the
analyzer.

In the event of such an occurrence, to return the PM100 or PM300 to normal operation:
1) Switch off the power
2) Wait 5 seconds
3) Switch on again
