Siglent's SDM4055A is a professional digital multimeter with a 5" touchscreen and 5½ digit / 220,000 counts display resolution. This means that this multimeter has a high precision and offers the possibility to perform True-RMS measurements for AC voltage and current of up to 700V and 10A. Moreover, this multimeter can measure up to 4,800 samples/sec without sacrificing its display resolution.
In addition, this device combines accurate standard measurement functions with multiple mathematical functions and display choices, including histogram, trend graph, bar graph, statistics, hold measurement, dBm, ect. Furthermore, the SDM4055A can perform automatic measurements and can also be measured with a thermocouple (types B, E, J, K, N, R, S and T).
The SDM4055A has a 256 MB NAND flash size and has interfaces for external storage, namely USB device, USB host and LAN. The Ethernet connection interface supports the common SCPI command. Using the supplied software, the measured data can be displayed in a graph or saved.
