The RIGOL DM858 Series comprises compact 5½-digit, 120,000-count bench multimeters with True RMS measurement, graphical analysis and remote-control functions. Eleven input measurement capabilities cover voltage, current, two- and four-wire resistance, frequency, period, capacitance, temperature, continuity and diode testing for electronics development, maintenance and automated testing.
The DM858 provides up to 0.030% one-year DC voltage accuracy, 125 readings per second and 500,000-point data logging. The economical DM858E provides 0.060% one-year DC voltage accuracy, 80 readings per second and 20,000-point logging while retaining the same 5½-digit interface and core analysis workflow.
Key Features
-
5½-digit, 120,000-count resolution: Provides detailed readings for circuit development, component testing and measurement monitoring.
-
True RMS AC measurement: Supports accurate evaluation of AC voltage and current for both sinusoidal and non-sinusoidal signals within the specified measurement ranges.
-
Two- and four-wire resistance: Four-wire measurement reduces the influence of test-lead resistance when evaluating low-resistance components and connections.
-
Up to 125 readings per second: The DM858 captures faster measurement changes, while the DM858E provides up to 80 readings per second.
-
Graphical data analysis: Trend Chart, Histogram and Bar Graph views make changes, distributions and relative levels easier to interpret.
-
Integrated mathematical functions: Statistics, Limit Test, Relative, dB and dBm operations support analysis without requiring immediate external processing.
-
Universal sensor measurement: Ten preset sensor configurations and thermocouple cold-junction compensation support pressure, flow, temperature and other sensor measurements.
-
Large data-logging capacity: The DM858 records up to 500,000 points, while the DM858E stores up to 20,000 points.
-
7-inch color touchscreen: The 1024 × 600 display presents primary and secondary readings, status and statistical information together.
-
USB, LAN and Web Control: Standard connectivity and SCPI commands support browser-based operation, PC integration and automated test procedures.

Graphical and Mathematical Analysis
Trend Chart mode shows how a reading changes over time, making it useful for drift, warm-up and stability observations. Histogram mode displays the distribution of recorded measurements, while Bar Graph mode provides a quick visual indication of the current value.
Built-in statistics calculate maximum, minimum, average and standard deviation. Limit Test supports repetitive acceptance checks, Relative mode compares readings with a reference value, and dB/dBm functions support level measurements.
Universal Sensor Measurement
Ten preset sensor configurations simplify measurements using common sensor types. Built-in thermocouple cold-junction compensation supports temperature work, while customizable configurations allow pressure, flow, temperature and other sensors to be scaled into the required engineering units.
User-defined sensor configurations support DC voltage, DC current, two-wire resistance, four-wire resistance and frequency-based sensors.
Data Logging
The DM858 stores up to 500,000 readings for extended measurement analysis. The DM858E provides storage for up to 20,000 readings. Ten groups of history data, ten sensor configurations and ten instrument setups can be stored, while USB external storage supports additional data handling.
Connectivity and Automation
USB Host, USB Device and LAN interfaces are included as standard. Web Control allows the multimeter to be accessed through a browser, and SCPI command support enables integration with custom software, automated validation procedures and production test systems.
The USB-C power interface supports operation from a compatible mobile power source. A compact 80 mm-deep enclosure, desktop stand and VESA 100 × 100 mounting interface provide flexible positioning on space-limited benches.
