Safety Summary
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.

2
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.
If the instrument will not be used for a long period of time, remove the batteries.
When changing the instrument's batteries, disconnect all leads and wires connected to the
instrument before replacing the batteries. Replace with the battery types specified in this
manual.

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 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

polarity matches the (+) and (-) labels as indicated inside the battery compartment.
See “Installing Battery” section for details. DO NOT, at any time, connect an external
power adapter when a battery is installed incorrectly or is the wrong type. Doing so
will damage the instrument or the battery and void the instrument’s warranty.
Front Panel Buttons
With the exception of the power button, all front panel buttons have specific colored labels on
them. They are all marked in white, blue or yellow color. Each color has a specific
representation, as described below:
White—the primary function, these functions will be set or configured upon pressing the
button.
Blue—the secondary function, this function will be set or configured if that button is
pressed and held down for 2 seconds.
Yellow —the utility function, this function will be set or configured if the button is
pressed and held down for a couple of seconds. See “Utility Menu (UTIL)” section for details.

Test Port
The 880 is designed with two test ports: the 3-terminal port for convenience and a 5-terminal
port for higher accuracy.
Figure 3 - Test Ports
The standard banana plugs allow the connection of banana to alligator test lead. This
configuration has lower testing accuracy when compared to the 5-terminal test port. The test
lead length should be kept as short as possible.
For a more accurate measurement when using external testing leads, the 880 LCR meter is
designed with a 5-terminal test port and exclusive test fixtures that provide a 4-wire connection
with a shield for increased measuring accuracy.
