The SIGLENT SDM3055 is a 5½-digit dual-display digital multimeter offering 240,000-count readings resolution. The SDM3055/SDM3055-SC is designed for high-precision, multifunction, and automatic measurement, pairing a broad measurement set with a 4.3-inch TFT-LCD and dual-display operation, a built-in front-panel help system, and file management with U-disc and local storage.

Application fields include research and development laboratories, repair and maintenance, calibration laboratories, automatic production test, and general bench-top use. The dual-display and built-in help system support both interactive bench work and automated test environments.

ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, and each new unit is fulfilled directly from that facility.

Compare Other Models in This Series

The SDM3055 is offered in two configurations of the same 5½-digit digital multimeter: the SDM3055 and the SDM3055-SC. Both share identical core measurement performance — 240,000-count resolution, dual-display, True-RMS AC voltage and current, and up to 150 readings per second — differing in scanning capability.

Each configuration provides the full SDM3055 measurement set across DC and AC voltage and current, 2/4-wire resistance, capacitance, frequency, period, diode, continuity, and TC/RTD temperature, along with standard USB Host and LAN interfaces and SCPI remote control.

Each model below links to its own dedicated product page with condition-matched pricing for the new configuration you select. Review the specific model page to confirm the exact configuration before ordering.

The base SDM3055 delivers the complete measurement set — DCV, ACV, DCI, ACI, 2/4-wire resistance, capacitance, frequency, period, diode, continuity, and TC/RTD temperature — as a bench multimeter supplied without the Scanner Card SC1016.

The two configurations differ by the Scanner Card SC1016: it is not included with the SDM3055 and is included with the SDM3055-SC. The SC1016 multiplexer adds 12 multipurpose channels plus 4 current channels supporting DCV, ACV, DCI, ACI, 2-wire and 4-wire resistance, capacitance, frequency, diode, continuity, and temperature.

See the comparison table for the configuration breakdown, including which model carries the scanner card and the resulting multi-point measurement channel counts.

Model	Digits	Max Reading Rate	DC Voltage Range
SDM3055	5½ (240,000 counts)	150 rdgs/s	200 mV - 1000 V
SDM3055-SC	5½ (240,000 counts)	150 rdgs/s	200 mV - 1000 V

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Important: For continuous current higher than DC 7 A or AC RMS 7 A, 30 seconds off after 30 seconds on is recommended.

Important: To avoid electrical shock and personal injury, do not use the product to measure signals that exceed the published specification.

Important: The Scanner Card SC1016 is available only for the SDM3055-SC model (the standard SDM3055 does not accept it).

Important: Standard interfaces are USB Host and LAN; the USB-GPIB adapter is an optional accessory.

Recommended pairing: add the SIGLENT Scanner Card SC1016 (SDM3055-SC) for 12 multipurpose plus 4 current scanning channels covering DCV, ACV, DCI, ACI, resistance, capacitance, frequency, diode, continuity, and temperature.
