Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
True five and a half digit multimeter
The SDM4055A series digital multimeter has a 5 ½ digit readout resolution (220,000 count) with a full scale range of ±000000 to 219,999, making small current variations to large voltage fluctuations manageable.
High-speed measurement
With a maximum of 4,800 readings/second, the SDM4055A series offers excellent advantages in high-speed data acquisition and monitoring of small changes for a variety of application scenarios that require precise measurements.
Logger Functions
The SDM4055A supports data logging intervals from 0.1s ~ 3600 s, up to 2 M points to memory, up to 360 M points to file, and up to 100 hours of recording. In addition, the SDM4055A has excellent storage and recall capabilities, and can easily manage the instrument parameter files in the internal storage area and external USB storage devices. 512 MB RAM memory, 256 MB Nand-Flash, support for reading points, images, csv/xml, and other types of file storage, the user can create a folder, save the screen shot, copy, rename and delete the file, etc., to efficiently manage the data. Users can create folders, save screenshots, copy, rename and delete files, etc., for efficient data management.
Rich Math Operations
The SDM4055A series supports operations such as maximum value, minimum value, average value, standard deviation, dB/ dBm, and limit value. Not only can it quickly count various measurement data, but also perform pass/fail tests according to the preset upper and lower limits. In addition, it supports power unit display, which can show the relative relationship between the measured value and the reference value in dB; through the relative operation function, it can also accurately find out the difference between the actual measured value and the expected value.
Four display formats
SDM4055A supports four display modes, the digital display mode can make the measurement results clear at a glance; histogram can quickly identify the characteristics of the data distribution; trend graph can clearly observe the pattern of change of the data and predict the direction of the data; bar graph can quickly analyze the changes and patterns under different conditions. Efficiently meet the user's visual needs and data analysis habits, in-depth insight into the data.
Multi-function scanner card
The SDM4055A-SC is equipped with a multi-function scanner card (SC1016) that can extend the multimeter test channels to measure various circuit parameters quickly and accurately.The SC1016 has a 16-channel measurement interface (12 multi-function channels + 4 current channels), which allows simultaneous measurement of multiple circuit parameters at multiple test points or devices, and enables control of the device and scanner card through the host computer. .
Remote control and programming
SDM4055A is equipped with USB Host, USB Device, LAN standard communication interface, optional USB-GPIB module. It supports standard SCPI remote control commands and is compatible with the latest mainstream multimeter command sets. You can use Web Server to remotely control the multimeter directly through the web page, or use the host computer software to realize remote programming and communication needs.
