Advantest R6452E Digital multimeter

The Advantest R6452E is a dual-channel digital multimeter delivering simultaneous measurement of two independent signals with independent 5.5-digit displays. This full-function instrument combines high-resolution DC voltage accuracy (180 ppm + 5 digits) with sampling rates up to 80 SPS and support for thermocouple temperature measurement via rear-panel Type K input. Channel A offers nine measurement functions—DC and AC voltage, DC and AC current, 2-wire and low-power resistance, frequency, diode test, and continuity—while Channel B supports DC voltage, DC current, and AC current measurement. True RMS conversion is native to all AC measurements.
