The DMM4050 and DMM4040 are multifunctional precision measurement tools with high resolution and accuracy. They can measure voltage, current, resistance, frequency, period, capacitance, and temperature. They also have features such as graphical display mode, statistical mode, histogram mode, and Trendplot™ paperless recorder mode, which facilitate data analysis and recording. In addition, they support PC connection and programming control, with multiple interface ports and front and rear panel input terminals for easy connection and operation.
This manual introduces the DMM4050 and DMM4040 digital multimeters, highlighting their 6.5‑digit resolution, high accuracy (0.0024 % + 0.0005 V), and wide measurement ranges for voltage, current, resistance, frequency, period, capacitance and temperature. It also describes the Trendplot™ recording mode, dual‑display graphics, and built‑in USB host port for data logging.
The document lists the available front‑panel and rear‑panel interfaces (USB, RS‑232, IEEE‑488, Ethernet), SCPI compatibility, recommended accessories (test leads, spare fuse, power cord, NI LabVIEW SignalExpress software), and warranty information (three‑year warranty). Ordering information and optional service plans are also provided. This manual is written in Chinese.
