Safety Summary
The following safety precautions apply to both operatingand maintenancepersonnel and must
be followed during allphases 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 willvoid the warranty.
•Make all connections to the instrument before applying power.
•Do notoperate theinstrument in ways not specified bythis manual orby B&K Precision.
Failure to comply with these precautions or with warnings elsewhere in this manual violatesthe
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 IEC61010 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 isa 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 connectedto 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 notuse this instrument in an electrical environment with ahigher category ratingthan 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 tomaintain 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 onlythe 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'sfront 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.

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 airtemperatures 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 madebythis instrument may beoutside 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, appearsto be damaged, or if any liquid, chemical, or other
material gets on or inside the instrument, remove the instrument'spower cord, remove the
instrument from service, label it asnot 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.
