The Rigol DM3058E is a 5.5-digit digital multimeter delivering high-precision measurements across DC/AC voltage, current, resistance, capacitance, and frequency domains. Its 256×64 pixel LCD with dual-display capability enables simultaneous observation of two measurement characteristics from a single signal, while selectable reading speeds of 2.5, 20, or 123 readings per second accommodate both detailed analysis and rapid production testing. The instrument integrates mathematical operations—Max, Min, Average, Standard Deviation, Pass/Fail limits, dBm, dB, Relative Measurement, and Histogram—alongside sensor measurement support for six sensor types with built-in thermocouple cold junction compensation.
