RS PRO Bench Digital Multimeter True RMS, 5½ Digit, 10A AC/DC, 750V AC, RSDM3055

The RS PRO RSDM3055 Bench Digital Multimeter is an advanced, high-performance instrument designed for precise electrical measurement in research, laboratory, calibration, and industrial environments. With a real 5½ digit (120,000 count) dual-readout display, this benchtop multimeter provides reliable True RMS readings for both AC and DC voltage and current up to 10A, ensuring accuracy in demanding test scenarios.

This multimeter supports a broad range of electrical functions, measuring AC/DC current, AC/DC voltage, capacitance, continuity, resistance, frequency, period, diode, and temperature, making it ideal for all-around laboratory and automatic test system use. Its multiple measurement modes allow for minimum, maximum, average and standard deviation calculations, relative measurement, pass/fail analysis, trending, and bar chart visualization, supporting advanced statistical evaluation and in-depth diagnostics.

The RSDM3055 stands out with its high-speed measurement capability of up to 150 readings per second, backed by a powerful engine that guarantees swift data processing in dynamic testing environments. A built-in 1 GB NAND memory offers extensive storage for settings, historical measurement data, and external USB disk support, ensuring seamless workflow and data management integration.

Equipped with a large, easy-to-read 4.3-inch TFT LCD (280x272 pixel) screen, it supports double display operation, with multilingual menus (Chinese and English), built-in help system, and intuitive file management including local and U-disc storage. Cold Junction compensation is integrated for precise thermocouple temperature measurement.

Users benefit from robust connectivity, including USB device, USB host, LAN (Ethernet), and - with the RSDM3055A variant - GPIB compatibility. The instrument supports remote control via industry-standard SCPI or VXI11/USBTMC and integrates with National Instruments LabVIEW, ensuring flexibility in automated and advanced test systems.

With compact bench-friendly dimensions of 282 x 260 x 105 mm and a weight of approximately 3.3 kg, the RSDM3055 is durable and suitable for continuous use in calibration labs and production testing. Its comprehensive protection system complies with safety categories CAT I and CAT II up to 1000V, enhancing operator safety during high-voltage measurements.

Every unit is supplied with essential accessories: a USB cable, quick start guide, one pair of leads, one pair of alligator clips, EasySDM computer software, power cord, and a CD with EasyScope PC Software, along with complete safety guidelines for electrical test operations.

The RS PRO RSDM3055 Bench Multimeter sets industry standards for precision, reliability, and ease of integration, serving the needs of professionals in research labs, development, calibration, and automated manufacturing quality control.
