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:
ii
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
iv
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
v
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
vi
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.
