The Tektronix DMM4050 is a 6.5-digit precision benchtop multimeter engineered for research, development, and manufacturing environments requiring high-accuracy DC and AC measurements. This instrument consolidates multiple measurement functions into a single platform: DC voltage (100 mV to 1000 V), AC voltage to 1000 V, DC current (100 μA to 10 A), AC current to 10 A, resistance (10 Ω to 1 GΩ), frequency, period, capacitance, temperature, diode testing, and continuity. True RMS measurement capability handles both AC and AC + DC signals. The dual display permits simultaneous monitoring of two parameters from a single test connection, eliminating setup reconfiguration.
