The SDM4055A digital multimeter and SDM4055A-SC digital multimeter are designed with 5 ½ digits readings resolution and dual-display, especially fitting to the needs of high-precision, multifunction and automatic measurement.
SDM4055A offers four modes: Numeric for instant clarity, Histogram for data distribution analysis, Trend Chart for dynamic data pattern observation and trend prediction, and Bar Chart for cross-condition comparisons and rapid analysis of variations and patterns under different conditions, empowering users to visualize and analyze data with deeper insights.
SDM4055A支持数据记录间隔 0.1s ~ 3600 s，最大可记录到内存 2 M 点，最大可记录到文件 360 M 点，最长可记录 100 小时。此外，其具有出色的存储与调用能力，可在内部存储区和外部USB存储设备上轻松管理仪器参数文件。512 MB RAM存储器、256 MB Nand-Flash，支持读数点，图片，csv/xml等多种类型文件存储，用户可创建文件夹、保存屏幕截图、复制、重命名和删除文件等操作，高效进行数据管理
SDM4055A supports five operations: statistics, limits, dBm, dB, and relative measurements. It rapidly calculates max/min, average, peak-to-peak, standard deviation, and sample count, while enabling pass/fail testing via preset thresholds. Voltage-to-power conversion, dB-based relative measurements, and deviation analysis further enhance versatility.
