USER MANUAL

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

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 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 120 V RMS or 240 V

RMS. Use only the power cord supplied with the instrument and

iii

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 0 °C to 40 °C and the

operating humidity 90% 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

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.

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.

Cooling fans

vii

This instrument contains one or more cooling fans. For continued safe

operation of the instrument, the air inlet and exhaust openings for

these fans must not be blocked nor must accumulated dust or other

debris be allowed to reduce air flow. Maintain at least 25 mm clearance

around the sides of the instrument that contain air inlet and exhaust

ports. If mounted in a rack, position power devices in the rack above the

instrument to minimize instrument heating while rack mounted. Do not

continue to operate the instrument if you cannot verify the fan is

operating (note some fans may have intermittent duty cycles). Do not

insert any object into the fan's inlet or outlet.

Use correctly sized wires

To connect a load to the power supply, use a wire diameter large

enough to handle the maximum continuous output short-circuit current

of the power supply without the wire overheating.

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.
