Siglent SDM3065X Digital Multimeter, 6 1/2 Digits, Trms, 1000VDC, 10A, SDM3000 Series

Siglent SDM3065X Digital Multimeter Overview

The Siglent SDM3065X is a 6½-digit digital multimeter designed for high-accuracy, high-precision bench and automated test measurements. With 2,200,000-count resolution, a dual-display interface, True-RMS AC voltage and current measurement, and a 4.3-inch TFT-LCD screen, the SDM3065X gives engineers, technicians, and lab teams a versatile DMM for dependable electrical characterization. It supports core measurements including DC voltage, DC current, AC voltage, AC current, 2-wire and 4-wire resistance, capacitance, frequency, period, continuity, diode testing, and temperature measurement with thermocouple and RTD sensors. Built-in storage, USB and LAN interfaces, SCPI remote-control support, and EasyDMM software compatibility make the Siglent SDM3065X a strong choice for research labs, development labs, calibration environments, maintenance benches, and automated production testing.

Specifications and Benefits

• 6½-digit resolution with 2,200,000 counts: Delivers fine measurement detail for high-precision digital multimeter applications.

• DC voltage range from 200 mV to 1000 V: Supports low-level circuit checks through higher-voltage bench testing.

• DC current range from 200 μA to 10 A: Helps measure small device currents as well as higher-current test points.

• True-RMS AC voltage from 200 mV to 750 V: Provides accurate AC measurements for sine-wave and applicable AC signal testing.

• True-RMS AC current from 200 μA to 10 A: Expands AC troubleshooting and characterization capability across multiple current ranges.

• 2-wire and 4-wire resistance from 200 Ω to 100 MΩ: Enables flexible resistance measurement, with 4-wire support helping reduce lead-resistance error.

• Capacitance from 2 nF to 100 mF: Allows component-level capacitance checks across a wide practical range.

• Frequency measurement from 3 Hz to 1 MHz and period measurement from 1 μs to 333.33 ms: Adds timing and signal verification capability without requiring a separate counter for many bench tasks.

• Temperature measurement with thermocouple and RTD sensor support: Helps combine electrical and temperature data in lab, maintenance, and calibration workflows.

• Math and display tools including Min, Max, Average, Standard Deviation, dBm/dB, Relative, Pass/Fail, Histogram, Trend Chart, and Bar Meter: Makes it easier to analyze changes, monitor trends, and identify out-of-limit results directly on the instrument.

• 4.3-inch TFT-LCD display with 480 × 272 resolution and dual measurement display: Improves visibility and lets users view two measurement values at once.

Siglent SDM3065X FAQ

1. Does the Siglent SDM3065X support automated testing and remote control?
   Yes. The SDM3065X includes USB Device, USB Host, plus a LAN interface and supports remote operation through SCPI commands. These features make it practical for automated production test and remote data collection.

2. What is the difference between the SDM3065X and SDM3065X-SC?
   The SDM3065X-SC includes the SC1016 scanner card, while the standard SDM3065X does not and can't be added later. The scanner card provides multi-point measurement capability with 12 multi-purpose channels and 4 current channels, supporting functions such as voltage, current, resistance, capacitance, frequency, diode, continuity, and temperature measurements for applications that need multiple test points. These usability features help simplify measurement setup, data handling, and daily bench operation for laboratory, development, calibration, maintenance, and production test users.

3. How do you log data to a PC, and is the software free?
   Yes, the software is free. Siglent provides EasyDMM software for controlling the meter and logging data directly to a PC. The unit also supports standard SCPI commands, allowing you to easily integrate it into custom Python, LabVIEW, or MATLAB automated test scripts using the built-in USB or LAN ports.
