The instrument features a high-contrast 4.3-inch full color LCD with histogram, bar meter, and trend chart display modes, dual measurement display, and USB (USBTMC-compliant), RS232, and LAN interfaces. Rear input terminals are included for rack-mount use. ### What is the B&K Precision 5493C used for? The B&K Precision 5493C is used by engineering, production, and service teams for general-purpose precision measurement at the bench. Its 6½-digit resolution and 35 ppm basic DC voltage accuracy place it in the precision tier alongside the Keysight 34461A and Fluke 8845A — appropriate for calibration verification, R&D characterization, automated test systems, and any application where 5½-digit resolution leaves measurement noise floor on the table. The instrument's 12 measurement functions and 4.3-inch color display make it suitable as a primary bench DMM in a small lab or as a programmable measurement node in an automated test system. ### How does the 5493C compare to a basic 3½-digit handheld multimeter? A handheld 3½-digit or 4½-digit DMM resolves 2,000 to 20,000 counts and typically delivers 0.5% to 0.05% basic DC accuracy — adequate for field troubleshooting but not for measurements that feed design data or quality records. The 5490C Series is a **bench precision** instrument: 6½-digit (1,200,000-count) resolution (1,200,000 counts), 0.0035% (35 ppm) basic DC accuracy, programmable control via USB (USBTMC-compliant), RS232, and LAN, a 10,000-reading internal buffer for data logging, and dual measurement display for simultaneous viewing of two measurements such as AC voltage and frequency on the same screen. A bench DMM and a handheld DMM are complementary instruments — the 5490C Series is the bench reference, not a field replacement. ### Factual Grounding — Specifications and Industry Context The 5493C delivers 0.0035% (35 ppm) basic DC voltage accuracy, a temperature coefficient of 5 ppm/°C on the 10 V range, measurement speeds up to 1000 readings per second, a 10,000-reading internal storage buffer, and 2-wire/4-wire resistance measurements down to 10 Ω with 0.1 mΩ resolution on the 10 Ω range (10 µΩ resolution at 6½ digits). The frequency function covers 3 Hz to 1 MHz with sine wave input, and capacitance measurement spans 1 nF to 10 mF in eight ranges. Temperature measurement is supported via Pt100 (DIN/IEC 751) RTD probes or 5 kΩ thermistor probes. The 4.3-inch full color LCD supports histogram, bar meter, and trend chart display modes with simultaneous min/max/peak-peak/average/standard deviation statistics over the captured buffer. Power consumption is ≤ 30 VA from 110 V/220 V ±10% AC mains; the instrument weighs 5.51 lbs (2.5 kg) in a 8.85" × 3.93" × 13.97" half-rack form factor. ### Entity Authority — B&K Precision and the Bench Precision DMM Category B&K Precision Corporation has provided reliable, value-priced test and measurement instruments worldwide for more than 60 years. Headquartered in Yorba Linda, California, the company is ISO9001:2015 registered (NSF-ISR, certificate 6Z241-IS8) and operates global subsidiaries in France (Sefram), Taiwan (B+K Precision Taiwan), and Brazil (B&K Brasil), with independent service support in Singapore for the broader Asia-Pacific market. The 5490C Series sits in the bench precision DMM category — instruments designed for calibration verification, automated test, and R&D measurement where 5½ to 6½ digits of resolution and sub-0.01% basic accuracy are required, and where programmable control via standard interfaces (USB, LAN, RS232, GPIB) is non-negotiable for system integration. Provided LabVIEW™ drivers simplify integration into existing measurement systems. ### How does the 5493C compare to other bench DMMs in the category? - **Resolution & accuracy:** 6½-digit (1,200,000-count), 0.0035% (35 ppm) basic DCV accuracy — directly comparable to the Keysight 34461A and Fluke 8846A precision tier. - **Measurement speed:** Up to 1000 readings per second, with a 10,000-reading internal buffer — appropriate for component characterization sweeps and automated production test logging. - **Display:** 4.3-inch full color LCD with histogram, bar meter, and trend chart graphical modes — a meaningful step beyond monochrome bench DMMs in the same price class. - **Connectivity:** USB (USBTMC-compliant), RS232, and LAN all standard (GPIB available on the 5493CGPIB variant) — full system integration without optional connectivity surcharges. - **Dual measurement:** Simultaneous display of two measurement results (e.g. AC voltage with frequency, or DC voltage with DC current) — a productivity feature not universal at this price tier. - **Temperature measurement:** Direct Pt100 (DIN/IEC 751) RTD or 5 kΩ thermistor support — useful for thermal characterization without an additional thermometer. - **Front panel USB host:** Direct screen-capture and measurement-data export to USB drive with date and time stamp — no PC required for data archival. - **Rear input terminals:** Included on the 6½-digit models for rack-mount installations and automated test system integration. ### What math, statistics, and display modes does the 5493C support? - **Math functions:** Null, dB, dBm, %, mx+b, and run/stop calculation modes - **Statistics:** Minimum, maximum, peak-to-peak, average, and standard deviation — displayed simultaneously over the captured buffer - **Display modes:** Numeric, bar meter (with upper/lower limit setpoints, PASS/FAIL indication and counter), trend chart (live data graphical view), and histogram (data distribution view with statistics) - **DC voltage ratio:** Displays the ratio between two separate DC voltage measurements within ±12 V — useful for input/output magnitude verification on low-voltage circuits - **Dual measurement display:** Simultaneous display of two measurement results (e.g. AC voltage + frequency, DC voltage + AC voltage) - **Probe hold mode:** Captures stable readings to a list of up to eight measurements for sequential comparison - **Real-time clock/calendar:** Date- and time-stamps all logged measurement data ## Accessories Supplied Standard accessories shipped in the box with every 5490C Series multimeter: Item Description Power cord Region-appropriate AC power cord USB cable USB cable for USBTMC-compliant remote control and data transfer Test leads Multimeter test leads for front-panel input terminals Spare fuses Replacement fuses for the current input Test report Factory test report documenting measurement performance Certificate of calibration Factory calibration certificate ### Optional Accessories - **RK02 —** Rack mount kit - **TL500B —** High performance bench DMM accessory kit - **TL130B —** General purpose DMM kit - **TL50B —** Maxi-Pro DMM kit - **TL37 —** Replacement probes ## Inside the 5493C — Design, Operation & Complete Specifications The bench precision multimeter is the measurement reference at the center of an engineer's bench. It is the instrument that converts unknown electrical quantities — DC voltage, AC voltage, current, resistance, capacitance, frequency, temperature — into trustworthy numbers that other instruments and analyses depend on. Within the precision DMM category, the difference between a 3½-digit handheld and a 6½-digit bench instrument is not just decimal places; it is the difference between a tool for finding problems and a tool that contributes to design records, calibration verifications, and quality documentation. The B&K Precision 5493C sits in the 6½-digit precision tier — the resolution class required for calibration verification, automated characterization, and any measurement that feeds design or quality data. ### 12 Measurement Functions — One Instrument, Twelve Measurements The 5490C Series consolidates twelve measurement functions into a single bench instrument with intuitive front-panel switching between modes. The function set is comprehensive enough that for most bench applications the 5490C Series replaces a stack of dedicated single-function instruments: **1\. DC Voltage (DCV)** 5 ranges from 100 mV to 1000 V, 0.0035% (35 ppm) basic accuracy, with 20% overrange on all ranges except 1000 V (5% overrange). **2\. AC Voltage (ACV)** True RMS measurement across 5 ranges (100 mV to 750 V) with three selectable low-frequency filters (3 Hz, 20 Hz, 200 Hz) for performance against the input signal's lowest frequency component. **3\. DC Current (DCI)** 7 ranges from 100 µA to 10 A; the 10 A range is available on the front panel only. **4\. AC Current (ACI)** True RMS AC current measurement across the same 7 ranges, with the same low-frequency filter options. **5\. 2-Wire Resistance** 8 ranges from 10 Ω to 100 MΩ; the NULL function compensates for test-lead resistance to recover full specified accuracy. **6\. 4-Wire Resistance** Same 8 ranges; the 4-wire (Kelvin) configuration measures the device under test independently of lead resistance — essential for resistances below 100 Ω. **7\. Capacitance** 8 ranges from 1 nF to 10 mF, with test currents from 10 µA to 10 mA depending on range. **8\. Frequency** 6 frequency bands from 2 Hz to 1 MHz for sine and square wave inputs, with 1-second gate time for best accuracy. **9\. Diode Test** 5 V range with 1 mA test current — measures forward voltage drop across a semiconductor junction. **10\. Temperature** Direct measurement via Pt100 (DIN/IEC 751) RTD or 5 kΩ thermistor probe; accuracy is the probe accuracy plus 0.05 °C (Pt100) or 0.10 °C (thermistor). **11\. Continuity Test** 1 kΩ range with 1 mA test current and audible beeper for go/no-go continuity verification. **12\. DC Voltage Ratio** Displays the ratio between two separate DC voltage measurements within ±12 V — useful for input-to-output magnitude verification on low-voltage circuits without external computation. ### The 4.3-Inch Color Display: Beyond Numeric Readout Conventional bench DMMs present readings as a single line of numbers — leaving the engineer to track stability, drift, and distribution manually over time. The 5490C Series replaces that with a 4.3-inch high-contrast color LCD that supports four display modes including **numeric** readout, **bar meter** with upper/lower limit setpoints and PASS/FAIL indication, **trend chart** showing live measurement values plotted against time, and **histogram** showing the distribution of measurements across the captured buffer with mean, standard deviation, and sample count overlaid. Bar meter and limit mode together create an inline production-test station: set the upper and lower limits, watch the PASS/FAIL counter, and the operator sees go/no-go status without interpreting the reading. Trend chart and histogram replace what would otherwise require exporting data to a PC and plotting in spreadsheet software. ### Dual Measurement Display, Probe Hold, and Statistics The dual measurement feature displays two measurement results simultaneously — AC voltage with frequency, DC voltage with AC voltage, or any other compatible pair — so the engineer reads both quantities from one screen without function switching. **Probe hold mode** captures stable readings to an on-screen list of up to eight values, designed for situations where the engineer is moving probe tips between test points and needs a hands-free record of each captured value. The **statistics display** presents minimum, maximum, peak-to-peak, average, and standard deviation over the captured buffer simultaneously — over a buffer that holds up to 10,000 data samples for trend analysis, characterization sweeps, or production logging. ### Remote Interfaces, Operating Software, and Front Panel USB The 5490C Series is built for system integration as well as bench use. Every model includes standard USB (USBTMC-compliant), RS232, and LAN interfaces (the 5493CGPIB variant adds GPIB). The USB connection is USBTMC-compliant for seamless integration with VISA-based control software. A **LabVIEW™ driver is provided** to simplify automated test system development and instrument control. The **front panel USB host port** accepts USB drives for direct save and recall of instrument settings, screen capture export, and measurement-data file export — all logged with date and time stamp from the multimeter's internal real-time clock. The provided B&K Precision operating software supports remote instrument control, live measurement monitoring, and data logging from a PC. ### Range Comparison: 6½-Digit Measurement Ranges The 5490C Series spans the full bench-measurement range across each function: - **DC Voltage:** 0.1 µV resolution to 1000 V - **DC Current:** 0.1 nA resolution to 10 A - **DC Resistance:** 10 µΩ resolution to 100 MΩ - **AC Voltage:** 1 mV resolution to 750 V (True RMS) - **AC Current:** 0.1 nA resolution to 10 A (True RMS) - **Capacitance:** 0.1 pF resolution to 10 mF - **Frequency:** 2.2 Hz to 1 MHz ## Complete Specifications — B&K Precision 5493C ### DC Voltage — 6½-digit Specifications _Accuracy: ± (% of reading + % of range). 24-hour specifications are typical relative to calibration standards (TCAL ±1 °C). 90-day and 1-year specifications valid for TCAL ±5 °C.
