1.3 SAFETY SUMMARY
Observe these general safety precautions during all phases of instrument operation, service, and repair. Failure to comply
with these precautions or with specific warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended instrument use. Lake Shore Cryotronics, Inc. assumes no liability for Customer failure to
comply with these requirements.
The Model 325 protects the operator and surrounding area from electric shock or burn, mechanical hazards, excessive
temperature, and spread of fire from the instrument. Environmental conditions outside of the conditions below may pose
a hazard to the operator and surrounding area.
• Indoor use.
• Altitude to 2000 m.
• Temperature for safe operation: 5 °C to 40 °C.
• Maximum relative humidity: 80% for temperature up to 31 °C decreasing linearly to 50% at 40 °C.
• Power supply voltage fluctuations not to exceed ±10% of the nominal voltage.
• Overvoltage category II.
• Pollution degree 2.
