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 specied 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 denes 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 denes 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 transformer 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 specied

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 ammable

atmosphere.

Do not operate the instrument in the presence of ammable gases or vapors, fumes, or nely-divided

particulates.

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

• In the presence of noxious, corrosive, or ammable fumes, gases, vapors, chemicals, or nely-divided

particulates.

• In relative humidity conditions outside the instrument’s specications.

• 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 specied operating temperatures.

• In atmospheric pressures outside the specied altitude limits or where the surrounding gas is not air.

• In environments with restricted cooling air ow, even if the air temperatures are within specications.

• In direct sunlight.

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

temperature range is 0∘C to 40∘C and 20% to 80% relative humidity, with no condensation allowed.

Measurements made by this instrument may be outside specications if the instrument is used in non-

oce-type environments. Such environments may include rapid temperature or humidity changes, sunlight,

vibration and/or mechanical shocks, acoustic noise, electrical noise, strong electric elds, or strong

magnetic elds.

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

www.GlobalTestSupply.com

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 qualied 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 rst 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 qualied service-trained maintenance personnel who are aware of

the instrument’s fuse requirements and safe replacement procedures. Disconnect the instrument from

www.GlobalTestSupply.com

Find Quality Products Online at: sales@GlobalTestSupply.com

the power line before replacing fuses. Replace fuses only with new fuses of the fuse types, voltage

ratings, and current ratings specied 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 re. Failure to use the specied fuses

will void the warranty.

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 ow 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.
