Key Features
Core Measurement Performance
-
5.5-Digit Resolution: Delivers up to 120,000 counts of high-accuracy resolution.
-
1 Year DCV Accuracy: High precision rated at 0.030% for the base DM858 model (and 0.060% for the DM858E).
-
Reading Speed: Capable of up to 125 readings per second (80 readings/s on the DM858E) for fast data acquisition.
-
Massive Data Logging: Built-in memory records up to 500,000 points (20,000 points on the DM858E) for extensive signal and drift analysis.
-
11 Core Input Measurements: Supports True-RMS AC/DC Voltage, AC/DC Current (up to 10A on DM858 / 3A on DM858E), 2-wire and 4-wire Resistance, Capacitance (up to 10mF), Frequency/Period, Diode, Continuity, and Temperature.
Visualization & Software Functions
-
Dual-Measurement Interface: Displays both main and auxiliary measurement parameters concurrently (e.g., viewing standard readings alongside statistical or real-time state configurations).
-
Advanced Graphical Formats: Supports 3 intuitive on-screen data visualization formats—Trend Charts, Histograms, and Bar Charts—eliminating the need for an external PC to observe signal behavior over time.
-
Built-in Math Operations: Includes multiple automated math capabilities such as Limits testing, Statistics, dB/dBm, and Relative operations.
-
Custom Sensor Presets: Features 10 sets of preconfigured standard sensor mapping options (including internal thermocouple cold-junction compensation) to easily translate voltage/resistance into physical properties like pressure or flow.
Form Factor & Connectivity
-
7-inch HD Color Touch Screen: Uses a crisp 1024×600 resolution panel that allows smooth navigation and quick terminal parameter adjustments.
-
Ultra-Thin Desktop Profile: Features a lightweight 1.25 kg body with an incredibly slim depth of just 80 mm, radically maximizing active workbench real estate compared to previous generations.
-
VESA Mount Capability: Includes a standard VESA 100×100 layout pattern on the back panel, allowing the instrument to be easily suspended on monitor arms.
-
Type-C Power Supply Interface: Powered via a flexible USB Type-C input terminal. It can run on common mobile power banks (such as a 65W power bank) for up to 8 hours of standalone field deployment.
-
Remote Control Options: Standard USB Host, USB Device, and LAN interfaces natively support SCPI automation commands alongside direct Web Control browser monitoring.
