great stability and fast measurement rates. The meters provide a maximum measurement rate of 25
readings/sec and a 0.02% and 0.03% DC voltage basic accuracy for model 5491B and 2831E
respectively. Both meters have broad ranges that can measure:
 DC voltage up to 1000 V
 AC (RMS) voltage up to 750 V
 DC current up to 20 A
 AC (RMS) current up to 20 A
 Two -wire resistance up to 20 MΩ (50 MΩ for model 5491B)
 Frequency from 10 Hz to 1 MHz
Some additional capabilities:
 Full range of functions: In addition to those listed above, the meter functions include period, dB,
dBm, continuity, diode testing, max, min and percent.
Programming languages and remote control interfaces: The meters are programmable via USB
(Virtual COM) interface using SCPI commands
