Siglent SDM4055A-SC 5.5 Digits 4800 rdgs/s digital multimeter + 16CH Scanner Card
The Siglent SDM3055A-SC is a 4800 rdgs/s high-performance 5½ digit digital multimeter equipped with the SC1016 16-channel scanner card, making it ideal for automated, multi-point measurements in R&D, production testing, and quality control. Featuring a crisp 4.3-inch TFT display, the scanner card has a fast reading rate of up to 150 rdgs/s, and built-in data logging capabilities, the SDM3055A-SC delivers reliable performance and streamlined operation for high-throughput testing environments.
SDM4055A-SC — 5½ digit touchscreen multimeter
The SDM4055A-SC is a 16-channel measurement system in a bench multimeter's footprint: the touchscreen SDM4055A with the SC1016 scanner card factory-installed — 12 multi-purpose channels plus 4 real current channels, scanned automatically with time-stamped logging.
The measurement engine is the full SDM4055A — DC/AC voltage to 1000 V (True-RMS), current to 10 A, 2/4-wire resistance, capacitance, frequency and TC/RTD temperature — and the SC1016 card routes it across 16 channels: 12 multi-purpose inputs (CH1–CH12) and 4 dedicated current channels (CH13–CH16). Scan lists are configured per channel on the touch display, each point with its own function and limits, and every scan is time-stamped into memory or streamed over USB/LAN with EasyDMM.

Application examples
Automated production testing
In manufacturing environments the SDM4055A-SC integrates into automated setups over SCPI, its 16-channel scanner card performing multi-point functional tests on assemblies or burn-in monitoring without manual intervention.
Multi-point thermal characterisation
Twelve thermocouples or RTDs across heatsinks and enclosures scan in one time-stamped list with cold-junction compensation — the documented thermal picture reliability engineers need.
Rail and shunt monitoring
The four dedicated current channels measure supply currents through shunts directly, alongside rail voltages, in a single scan — no external switching hardware in the rack.
Long-term logged testing
With 2 million readings to memory and up to 360 million to file, week-long environmental or endurance runs stay fully logged and exportable through EasyDMM-X.
A measurement system, not just a meter
Four views on a 5″ multi-touch display
Numerical, bar meter, trend chart and histogram — switch with a tap. True-RMS AC, 2/4-wire resistance, capacitance, frequency and TC/RTD temperature are all built in.
SC1016: 16 channels installed
The factory-installed scanner card multiplexes 16 channels — 12 multi-purpose (CH1–CH12) plus 4 dedicated current channels (CH13–CH16) — scanning voltages, resistances, currents and temperatures with time-stamped logging. Factory-installed only: not a field upgrade.
Who it’s for & why
Pick the SDM4055A-SC when the number of test points outgrows the number of hands: burn-in racks with a dozen thermocouples, power boards where every rail and shunt needs a logged history, environmental chambers where sensors run for days. The four dedicated current channels are the differentiator — current loops and shunts scan natively, without external switching hardware. And because the SC1016 is factory-installed only, the -SC is the safe choice whenever multi-point measurement might ever be needed.
