The Keithley DMM6500 is a 6.5-digit bench and system multimeter engineered for precision measurement across research, development, manufacturing, and laboratory environments. Its 5-inch capacitive touchscreen delivers a graphical interface with pinch-and-zoom capability for intuitive data visualization. The instrument integrates 15 measurement functions—DC voltage, AC voltage, DC current, AC current, resistance, capacitance, frequency, temperature (RTD, thermistor, thermocouple), diode test, and digitizing—enabling comprehensive electrical characterization without external instrumentation.
At its core sits a 16-bit digitizer operating from 1 kS/s to 1 MS/s, storing up to 7,000,000 readings for transient capture and analysis. The DMM6500 delivers measurement rates to 21,000 readings per second with a minimum measurement time of 8.3 µs (10 µs at 50 Hz). DC voltage accuracy reaches 25 PPM (0.0025%) over one year and 30 PPM over two years.
