Advantest R6552 Digital multimeter

The Advantest R6552 is a 5.5-digit digital multimeter engineered for precision measurement across R&D, manufacturing, and service environments. It delivers DC and AC voltage and current measurements, resistance in 2-wire and 4-wire configurations, frequency analysis, and diode testing with True RMS accuracy. The 319,999-count fluorescent display and sampling speeds up to 1000 samples/sec in BURST mode enable rapid signal capture, while GPIB and RS232 interfaces support remote automation and data logging. Specialized modes—including (AC+DC) measurement for distorted waveforms and LONG-IT averaging—extend measurement capability in challenging signal conditions.
