Lake Shore Model 330 Autotuning Temperature Controller User's Manual
Electromagnetic Compatibility (EMC) for the Model 330 Temperature Controller
Electromagnetic Compatibility (EMC) of electronic equipment is a growing concern worldwide.
Emissions of and immunity to electromagnetic interference is now part of the design and manufacture of
most electronics. To qualify for the CE mark, the Model 330 meets or exceeds the generic requirements
of the European EMC directive 89/336/EEC. The instrument was tested under normal operating
conditions with sensor and interface cables attached. If the installation and operating instructions in the
User's Manual are followed, there should be no degradation in EMC performance.
Pay special attention to instrument cabling. Improperly installed cabling may defeat even the best EMC
protection. For the best performance from any precision instrument, follow the grounding and shielding
instructions in the User's Manual. In addition, the installer of the Model 330 should consider the
following:
• Leave no unused or unterminated cables attached to the instrument.
• Make cable runs as short and direct as possible.
• Do not tightly bundle cables that carry different types of signals.
• Add the clamp-on ferrite filter (part number 109-053) included with the connector kit to the serial
interface cable near the instrument rear panel when that interface is used.
