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.

iii
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, 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 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 range is up 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

v
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.

2Getting Started
Before connecting and powering up the instrument, please review and go through the
instructions in this chapter.
2.1 Input Power and Fuse Requirements
Input Power
The supply has a selectable AC input that accepts line voltage input within:
Voltage: 110 V (+/- 10 %) or 220 V (+/- 10 %)
Frequency: 47 Hz – 63 Hz
Before connecting to an AC outlet or external power source, be sure that the power switch is in
the OFF position and verify that the AC power cord, including the extension line, is compatible
with the rated voltage/current and that there is sufficient circuit capacity for the power supply.
Once verified, connect the cable firmly.
The included AC power cord is safety certified for this
instrument operating in rated range. To change a
cable or add an extension cable, be sure that it can
meet the required power ratings for this instrument.
Any misuse with wrong or unsafe cables will void the
warranty.
SHOCK HAZARD:
The power cord provides a chassis ground through a
third conductor. Verify that your power outlet is of the
three-conductor type with the correct pin connected
to earth ground.
