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 opera tional informatio n i n thi s ma nual.
• 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 me a s ure m ent i nputs are not intended to
be connected to the mains supply. The voltages in the environment are typically derived from a
limited-energy transforme r 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 enter ing a building or other outdoor wiring.
i
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 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, thr ee-conductor AC line power cable. The power cable must be plugged into an
approv ed 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.
ii
Do not operate in an explosive or flammable atmosphere
Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finelydivided 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
operati ng t e mpera ture r a nge is 0 °C to 40 °C and the operating humidity range is up to 95%
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 ele c tr i c fi elds, or strong magnetic fie lds.
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 ope rated, and return the instrument to B&K
iii
Precision for repair. Notify B&K Precision of the nature of any contamination of the instrument.
Clean the instrument onl y as ins truc ted
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 hum an body or for us e 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 adj ustments m u st be made by quali fied 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 ar e 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 measurement s by testing with known-operating voltage sources and test for both DC and
AC voltages. Do not attempt any servi c e 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.
iv
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 proced ures. Disc onnect 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.
