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
customerâĂŹs 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 baery.
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.

SAFETY SUMMARY ii
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 oice-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.

SAFETY SUMMARY iii
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 specifications if the instrument is used in non-oice-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.

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 aer making the measurements by testing with
known-operating voltage sources and test for both DC and AC voltages. Do not aempt 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
