B+K precision 2560B Series Manuale utente

Safety Summary

The following safety precautions apply to both operating and maintenance personnel and must be followed during all

phases of operation, service, and repair of this instrument.

Before applying power to this instrument:

•

Read and understand the safety and operational information in this manual.

•

Apply all the listed safety precautions.

•

Verify that the voltage selector at the line power cord input is set to the correct line voltage. Operating the instrument

at an incorrect line voltage will void the warranty.

•

Make all connections to the instrument before applying power.

•

Do not operate the instrument in ways not specified by this manual or by B&K Precision.

Failure to comply with these precautions or with warnings elsewhere in this manual violates the safety standards of design,

manufacture, and intended use of the instrument. B&K Precision assumes no liability for a customer’s failure to comply

with these requirements.

Category rating

The IEC 61010 standard defines safety category ratings that specify the amount of electrical energy available and the

voltage impulses that may occur on electrical conductors associated with these category ratings. The category rating is

a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of the circuit to be tested,

which defines the voltage impulses expected and required insulation clearances. These categories are:

Category I (CAT I):

Measurement instruments whose measurement inputs are not intended to be connected to the

mains supply. The voltages in the environment are typically derived from a limited-energy trans-

former or a battery.

Category II (CAT II):

Measurement instruments whose measurement inputs are meant to be connected to the mains

supply at a standard wall outlet or similar sources. Example measurement environments are portable

tools and household appliances.

Category III (CAT III):

Measurement instruments whose measurement inputs are meant to be connected to the mains

installation of a building. Examples are measurements inside a building’s circuit breaker panel

or the wiring of permanently-installed motors.

Category IV (CAT IV):

Measurement instruments whose measurement inputs are meant to be connected to the primary

power entering a building or other outdoor wiring.

Do not use this instrument in an electrical environment with a higher category rating than what is specified in this manual

for this instrument.

You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the

instrument’s category rating to maintain the instrument’s category rating. Failure to do so will lower the category rating

of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be

115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your

country of use.

Ground the Instrument

To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This

instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable. The power

cable must be plugged into an approved three-conductor electrical outlet. The power jack and mating plug of the power

cable meet IEC safety standards.

Do not alter or defeat the ground connection. Without the safety ground connection, all accessible conductive parts

(including control knobs) may provide an electric shock. Failure to use a properly-grounded approved outlet and the

recommended three-conductor AC line power cable may result in injury or death.

Unless otherwise stated, a ground connection on the instrument’s front or rear panel is for a reference of potential only

and is not to be used as a safety ground. Do not operate in an explosive or flammable atmosphere.

Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finely-divided particulates.

The instrument is designed to be used in office-type indoor environments. Do not operate the instrument

•

In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided particulates.

•

In relative humidity conditions outside the instrument’s specifications.

•

In environments where there is a danger of any liquid being spilled on the instrument or where any liquid can condense

on the instrument.

•

In air temperatures exceeding the specified operating temperatures.

•

In atmospheric pressures outside the specified altitude limits or where the surrounding gas is not air.

•

In environments with restricted cooling air flow, even if the air temperatures are within specifications.

•

In direct sunlight.

This instrument is intended to be used in an indoor pollution degree 2 environment. The operating temperature range is

∘

C to 40

∘

C and 20% to 80% relative humidity, with no condensation allowed. Measurements made by this instrument

may be outside specifications if the instrument is used in non-office-type environments. Such environments may include

rapid temperature or humidity changes, sunlight, vibration and/or mechanical shocks, acoustic noise, electrical noise,

strong electric fields, or strong magnetic fields.

Do not operate instrument if damaged

If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other material gets on or inside the

instrument, remove the instrument’s power cord, remove the instrument from service, label it as not to be operated,

and return the instrument to B&K Precision for repair. Notify B&K Precision of the nature of any contamination of the

instrument.

Clean the instrument only as instructed

Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants, solvents, acids/bases,

or other such chemicals. Clean the instrument only with a clean dry lint-free cloth or as instructed in this manual. Not

for critical applications

This instrument is not authorized for use in contact with the human body or for use as a component in a life-support

device or system.

Do not touch live circuits

Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments must

be made by qualified service-trained maintenance personnel who are aware of the hazards involved when the instrument’s

covers and shields are removed. Under certain conditions, even with the power cord removed, dangerous voltages may

exist when the covers are removed. To avoid injuries, always disconnect the power cord from the instrument, disconnect

all other connections (for example, test leads, computer interface cables, etc.), discharge all circuits, and verify there

are no hazardous voltages present on any conductors by measurements with a properly-operating voltage-sensing device

before touching any internal parts. Verify the voltage-sensing device is working properly before and after making the

measurements by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt

any service or adjustment unless another person capable of rendering first aid and resuscitation is present.

Do not insert any object into an instrument’s ventilation openings or other openings.

Hazardous voltages may be present in unexpected locations in circuitry being tested when a fault condition in the circuit

exists.

Fuse replacement must be done by qualified service-trained maintenance personnel who are aware of the instrument’s fuse

requirements and safe replacement procedures. Disconnect the instrument from the power line before replacing fuses.

Replace fuses only with new fuses of the fuse types, voltage ratings, and current ratings specified in this manual or on

the back of the instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a fire. Failure

to use the specified fuses will void the warranty.

Note:

Servicing

Do not substitute parts that are not approved by B&K Precision or modify this instrument. Return the instrument to

B&K Precision for service and repair to ensure that safety and performance features are maintained.

For continued safe use of the instrument

•

Do not place heavy objects on the instrument.

•

Do not obstruct cooling air flow to the instrument.

•

Do not place a hot soldering iron on the instrument.

•

Do not pull the instrument with the power cord, connected probe, or connected test lead.

•

Do not move the instrument when a probe is connected to a circuit being tested.
