2Model 372 Quick Start Guide
Safety Precautions
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 372 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
Ground the Instrument
To minimize shock hazard, the instrument is equipped with
a 3-conductor AC power cable. Plug the power cable into an
approved 3-contact electrical outlet or use a 3-contact adapter
with the grounding wire (green) firmly connected to an electrical
ground (safety ground) at the power outlet. The power jack and
mating plug of the power cable meet Underwriters Laboratories
(UL) and International Electrotechnical Commission (IEC) safety
standards.
Ventilation
The instrument has ventilation holes in its top and side covers. Do
not block these holes when the instrument is operating.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable
gases or fumes. Operation of any electrical instrument in such an
environment constitutes a definite safety hazard.
Keep Away from Live Circuits
Operating personnel must not remove instrument covers. Refer
component replacement and internal adjustments to qualified
maintenance personnel. Do not replace components with power
cable connected. To avoid injuries, always disconnect power and
discharge circuits before touching them.
Do Not Substitute Parts or Modify Instrument
Do not install substitute parts or perform any unauthorized
modification to the instrument. Return the instrument to an
authorized Lake Shore Cryotronics, Inc. representative for service
and repair to ensure that safety features are maintained.
Cleaning
Do not submerge instrument. Clean only with a damp cloth and
mild detergent. Exterior only.
Desktop Installation
When installing the instrument in a desktop environment, ensure it
is mounted on a flat, level surface.
