- Digital multimeter measures current, voltage, resistance, and frequency.
- True RMS (root mean square) meter provides accurate readings when measuring linear or nonlinear loads where the current or voltage has an undistorted or distorted waveform.
- Dual LCD shows two readings at once.
- Audible continuity sensor confirms a circuit conducts electricity, and diode test detects proper functioning of a circuit’s diodes.
- Meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for Category I installations up to 1,000V and Category II installations up to 300V.
The BK Precision 2831E 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 dual LCD displays two readings at once, such as
voltage and resistance. 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 user can set high and low limits for pass/fail
testing. The meter displays the present measurement or the
highest or lowest reading in a session, for tracking sudden
changes in readings. 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 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 precise the measurement. The USB interface connects the
meter to a computer for data transfer and remote operation (cable
sold separately).
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 20,000-count resolution, meaning
it can display up to 19,999 units (4-1/2 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.
