The B&K Precision 2712 digital multimeter (also known as a
multitester) is a true RMS, auto- and manual-ranging meter for
measuring current, voltage, frequency, resistance, and
capacitance, and performs diode and continuity tests in
electrical applications. The AC + DC coupling measurement
provides the effective heating value of the AC and DC component
of the waveform. 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 and shows readings in digits and on a 34-segment bar graph.
It displays the present measurement or the highest or lowest
reading in a session, for tracking sudden changes in readings. 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 40,000-count resolution, meaning
it can display up to 39,999 units (4-3/4 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 1000V, which covers
large household appliances and devices connected to a fixed power
supply (such as refrigerators and air conditioners), 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), and Degree 2
for indoor use. The meter includes a set of detachable test
leads, a spare fuse, a 9V battery, a magnetic hanger, and
instructions.

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, multimeters 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. Multimeters 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 voltage. Safety ratings are based on International
Electrotechnical Commission (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.
