The BK Precision 5492B benchtop digital multimeter (also known as
a multitester) is a true RMS, auto-ranging meter for measuring
current, voltage, resistance, and frequency in electrical testing
and manufacturing applications and for teaching electrical
engineering principles. The meter comes with a set of detachable
test leads. The meter measures 2- and 4-wire resistance, for a
range of accuracy. An audible continuity sensor confirms a
circuit conducts electricity, and a diode test detects proper
functioning of a circuit’s diodes. The meter also measures
period. The meter's internal memory saves up to 10 measurement
settings for future recall. The meter's internal buffer can store
up to 512 readings and can use the stored data to provide
statistical information such as standard deviation and minimum,
maximum, and average readings, for tracking measurement trends
and sudden changes in readings. The user can set high and low
limits for pass/fail testing. The meter can also express AC and
DC voltage in decibels (dB), the power ratio of decibels to
milliwatts (dBm), and percent of the reading relative to a preset
reference value. The math mode manipulates readings according to
the formula mx + b, where m and b are user-entered constants for
scale factor and offset, respectively, and x is the actual
reading as would be normally displayed. The relative mode stores
a reading in memory to use as a zero point for subsequent
readings so that multiple readings can be compared. A hold
function keeps a reading on the display, even after the meter has
been disconnected. The user has a choice of slow, medium, or fast
measurement rate; the faster the rate, the less accurate the
measurements. USB and RS-232 interfaces connect the meter to a
computer for data transfer and remote operation (cable included).
Triggers can be set to respond to measurement, bus, front panel,
and external inputs.
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 120,000-count resolution, meaning
it can display up to 119,999 units (5-1/2 digits) before the
operating range needs to be changed. It meets International
Electrotechnical Commission (IEC) safety standard 61010 and is
certified for Category I installations up to 1,000V (which covers
protected electrical equipment such as small household
appliances) and Category II installations up to 300V (which
covers large household appliances and devices connected to a
fixed power supply, such as refrigerators and air conditioners).

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.
