Multimeters
Bench Multimeters
The 2831E (4 ½ digit) and 5491B (50,000-
count) bench digital multimeters provide
accurate and reliable measurements for
everyday use. These instruments measure
volts, ohms, and amps with great accuracy
and stability. Additionally, these multimeters
enhance productivity with built-in math
functions and USB connectivity for remote
controllability.
4 ½-digit and 50,000-count true RMS
Bench Multimeters
The 2831E and 5491B both offer a dual
display allowing multiple measurements to be
conveniently displayed at once.
Dual Display
Ideal for pass/fail testing, the limit operation
lets users set and control the values that
determine a HI / IN / LO status of
subsequent measurements.

Features & Benefits
■ Dual VFD display
■ AC+DC True RMS measurements
■ Math functions: Rel, Max/Min, dBm,
dB, %, Hold, Compare
■ Limit mode for Pass/Fail testing
■ CAT I (1000 V) / CAT II (300 V) protection
■ USB Interface (Virtual COM)
■ SCPI compatible
The 2831E and 5491B are programmable via USB (virtual com) 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.
