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 F71/F41 teslamter 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

 -20 °C to 70 °C, <90% relative humidity non-condensing

 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 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.

Exterior only.

Desktop Installation
When installing the instrument in a desktop environment, ensure it is mounted on a
flat, level surface.

Improper Use
If the instrument is used in a manner that is not specified by Lake Shore, the safety
protections provided by the instrument are no longer guaranteed, and may be
impaired.

Child Safety
This equipment is not suitable for use in locations where children are likely to be
present.
