True RMS Bench Multimeters

2831E and 5491B

True RMS Bench Multimeters with
Dual Display

The B&K Precision models 2831E and 5491B
are versatile and dependable bench multimeters
suitable for applications in education, service and
repair, and manufacturing requiring basic and
reliable measurements. Additionally, these
instruments enhance your productivity with
built-in math functions and USB connectivity,
features not found in other bench meters in this
price category. Math operations Rel, Max/Min,
dBm, dB, %, and Hold provide educators with a
convenient tool to teach basic math concepts.

5491B 50,000 4 3/4

Count Digits

The 2831E and 5491B take typical multimeter
measurements such as volts, ohms, and amps
with great accuracy, stability, and basic VDC
accuracy of 0.02% on the 5491B and 0.03% on
the 2831E. The meters are also capable of
measuring frequency, period, continuity, and
performing diode tests. Readings can be taken at
a maximum rate of 25 readings/sec with
measurement rates selectable between slow,
medium, and fast.

Thes multimeters were designed for
cost-conscious users requiring a basic and
dependable meter with a broad range of features
offered at a value price.

Versatile tools

▲

Dual Display

These meters offer a dual display allowing
multiple measurements to be conveniently
displayed at once. The display values could be
two different measurements or one measurement
expressed in different units. For example, you can
simultaneously read an AC voltage and a
frequency value or a DC voltage value expressed
in volts and in dB.

Limit Operation

The limit operation lets you set and control the
values that determine a HI / IN / LO status of
subsequent measurements. The meter can be
configured to emit an audible alarm when
readings are outside of the configured limit.

Increase Productivity with PC
Connectivity

The 2831E and 5491B are programmable via
USB and RS232 (5491B only) interface using
industry standard SCPI commands. Users can
control and configure the instrument from a
remote PC and retrieve measurement results for
further analysis. The meters can also be remotely
controlled using application software (download­able from the B&K website), which supports front
panel emulation and data logging of
measurement results.
