The BK Precision 2709B digital multimeter (also known as a
multitester) is a true RMS, auto-ranging meter for measuring
current, voltage, resistance, capacitance, and frequency in
electrical testing applications. The meter comes with a set of
detachable test leads. An audible continuity sensor confirms a
circuit conducts electricity, and a diode test detects proper
functioning of a circuit’s diodes. The LCD is backlit for
readability in low light. It displays the present measurement or
the highest or lowest reading in a session, for tracking sudden
changes in readings. The relative mode stores a reading in memory
to use as a zero point for subsequent readings so that multiple
readings can be compared. An alarm sounds when the test leads are
connected to the wrong jack for the measurement being taken. The
unit automatically turns off after 30 minutes of nonuse to
conserve battery life, and a low-battery indicator signals when
the meter's batteries need to be replaced. A magnetic strap is
included for hanging the meter from a metal door or surface for
hands-free use.
This true RMS (root mean square) meter provides accurate readings
when measuring linear loads, such as standard induction motors
and incandescent lights, where the current or voltage has an
undistorted waveform, or nonlinear loads, such as electronic
devices or motors, where the current or voltage has a distorted
waveform. When turned on, the meter is in auto-ranging mode and
automatically selects the correct operating range for the
property being measured. It can be switched to manual-ranging
mode, which allows the operator to choose the appropriate
operating range. The LCD has a 6,600-count resolution, meaning it
can display up to 6,599 units (3-3/4 digits) before the operating
range needs to be changed. It meets International
Electrotechnical Commission (IEC) safety standard 61010 and is
certified for Category II installations up to 1,000V, which
covers large household appliances and devices connected to a
fixed power supply (such as refrigerators and air conditioners),
and Category III installations up to 600V, which covers items
used with enclosed building circuit installations (such as
service panel parts, branch circuits, and fixed installations
that are connected directly to a building's AC power supply).

Multitesters (also called multimeters) are electrical test meters
that measure multiple properties of an electrical circuit, such
as current, voltage, resistance, capacitance, and continuity.
Available in handheld or benchtop models, multitesters diagnose
electrical problems in electrical equipment, wiring, and power
supplies. A variety of probes, clamps, and leads can be used to
connect the meter to a circuit or device. Multitesters display
information either in analog or digital form. Factors that
influence meter choice include the electrical properties to be
measured, the anticipated range of results, and the desired level
of protection against transient voltages. Safety ratings are
based on the International Electrotechnical Commission's (IEC)
standards for low-voltage test equipment. IEC 61010 delineates
four overvoltage installation categories. In general, a meter
with a category IV rating will provide more protection against
transient voltages than a meter with a lower category rating.
