Data Sheet True RMS Bench Multimeter 5492B True RMS Bench Multimeter The B&K Precision model 5492B is a versatile 5½-digit, 120,000-count bench multimeter suitable for applications in education, service repair, and manufacturing. The instrument enhances your productivity with built-in math functions and USB connectivity. Rel, Max/Min, dBm, dB, %, and Hold functions provide educators with a convenient tool to teach basic math concepts. Additionally, the 5492B offers powerful features not commonly found in other 5½- digit DMMs such as advanced triggering, buffer storage operation, and a GPIB interface option. Features & benefits The 5492B measures volts and amps with great accuracy and stability, with basic VDC accuracy of 0.01%. The meter is also capable of measuring frequency, period, resistance, continuity, and performing diode tests. Readings can be taken at a maximum rate of 57 readings/sec and stored to an internal 512-byte buffer for post acquisition statistical analysis. 5½-digit, 120,000-count display resolution ■ 0.01% basic VDC accuracy ■ Advanced triggering options such as external, ■ Two and four-wire resistance measurement up ■ AC voltage and AC current measurement over bus and event trigger to 120 MΩ wide frequency range (ACV 100 kHz/ACI 10 The 5492B was designed for cost-conscious users requiring an accurate meter with a broad range of features offered at a value price. Increase Productivity with PC Connectivity kHz) ■ AC (RMS) and DC current measurements up to 12 A ■ Limit mode for Pass/Fail testing ■ Save/recall up to 10 instrument settings ■ The 5492B is programmable via USB, RS232, and GPIB (5492BGPIB only) interface using industry standard SCPI commands. Users can remotely control and configure the instrument from a PC and retrieve measurement results for further analysis. The multimeter can also be remotely controlled using application software (via USB & RS232), which supports front panel emulation and data logging of measurement results.

The meter can be configured to emit an audible alarm when readings are outside of the configured limit. Front panel Input banana terminals Bright VFD display Advanced Triggering A variety of advanced trigger options are available: Manual Trigger via a front panel button press, Bus Trigger sending a *TRG command via PC interface, External Trigger using the EXT TRIG input terminal on the rear panel. Additionally, a trigger delay can be programmed after an event detection, and a VM Comp output is available to indicate the instrument’s completion of a present measurement. Fast Buffering with Built-in Statistics The 5492B provides an internal buffer capable of storing up to 512 readings. Buffer storage operation can be enabled via front panel or remote command. The buffer fills up with the requested number of readings at a rate of up to 57 readings/sec and then stops. The instrument automatically calculates statistical information based on the stored readings such as minimum, maximum, or average reading, and standard deviation, which can then be retrieved along with the readings via the front panel or remote command.
