DC/AC V & I, 2/4-wire resistance, frequency, continuity, diode, temperature, capacitance - 5½-digit resolution with reading rates up to 110 readings/s for speed-critical measurements - Signature 7-inch dual-measurement color display shows primary and secondary signal components at once - 5,000-point non-volatile logging memory for extended data recording and analysis - Standard USB and LAN connectivity with SCPI-1994.0 and IEEE-488.2 programming for automated test - Built-in USB flash drive port to copy/load instrument setups across multiple DMMs - Includes PathWave BenchVue DMM software for remote control and data logging The Keysight EDU34450A is a 5½-digit, dual-display digital multimeter designed for bench applications. It measures 11 input signals — DC voltage, DC current, true RMS AC voltage, AC current, two- and four-wire resistance, frequency, continuity, diode test, temperature, and capacitance — delivering broad measurement coverage in a low-cost, compact package. On the bench, the EDU34450A targets speed-critical tests with a reading rate of up to 110 readings per second, while its 5,000-point logging memory supports prolonged data recording and analysis. It is part of Keysight's education series, which also includes waveform generators, a triple-output DC power supply, and InfiniiVision 1000 X-Series oscilloscopes for a coordinated bench setup. ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house before it ships, while new units leave the warehouse factory-sealed exactly as received. That combination of held inventory and in-house verification means the EDU34450A you order is sourced and handled directly by our team. ## Brand Heritage Keysight Technologies traces its roots to Hewlett-Packard's test and measurement business, which was spun off as Agilent Technologies in 1999. Agilent's electronic measurement business then became Keysight Technologies in 2014, the brand under which this instrument is produced. ## Accessories Supplied - Power cord - Test leads ## Product Core & Specifications Specification Value DC Voltage Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 100.000 mV (10 MΩ or > 10 GΩ) 0.018 + 0.008 1.00000 V (10 MΩ or > 10 GΩ) 0.015 + 0.005 10.0000 V (10 MΩ) 0.025 + 0.005 100.000 V (10 MΩ) 0.025 + 0.005 1000.00 V (10 MΩ) 0.027 + 0.005 Resistance Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 100.000 Ω (1 mA) 0.065 + 0.010 1.00000 kΩ (500 µA) 0.065 + 0.008 10.0000 kΩ (100 µA) 0.065 + 0.005 100.000 kΩ (10 µA) 0.065 + 0.005 1.00000 MΩ (1 µA) 0.065 + 0.005 10.0000 MΩ (100 nA) 0.300 + 0.005 100.000 MΩ (100 nA / 10 MΩ) 2.000 + 0.005 DC Current Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 10.0000 mA (burden < 0.02 V) 0.10 + 0.015 100.000 mA (burden < 0.2 V) 0.10 + 0.007 1.00000 A (burden < 0.3 V) 0.30 + 0.015 3.0000 A (burden < 0.9 V) 0.30 + 0.007 Continuity / Diode Test (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) Continuity 1000 Ω (0.5 mA) 0.1 + 0.1 Diode test 1.0000 V (0.5 mA) 0.05 + 0.10 True RMS AC Voltage Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 100.000 mV, 20 Hz – 45 Hz 1.0 + 0.1 100.000 mV, 45 Hz – 10 kHz 0.2 + 0.1 100.000 mV, 10 kHz – 30 kHz 1.5 + 0.3 100.000 mV, 30 kHz – 100 kHz 6.0 + 0.3 1.00000 V to 750.00 V, 20 Hz – 45 Hz 1.0 + 0.1 1.00000 V to 750.00 V, 45 Hz – 10 kHz 0.2 + 0.1 1.00000 V to 750.00 V, 10 kHz – 30 kHz 1.5 + 0.3 1.00000 V to 750.00 V, 30 kHz – 100 kHz 3.0 + 0.3 True RMS AC Current Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 10.0000 mA to 3.0000 A, 20 Hz – 45 Hz 1.5 + 0.1 10.0000 mA to 3.0000 A, 45 Hz – 1 kHz 0.5 + 0.1 10.0000 mA to 3.0000 A, 1 kHz – 10 kHz 2.0 + 0.2 Frequency Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + 3 counts) 100.000 mV to 750.00 V, 20 Hz – 300 kHz 0.025 + 3 10.0000 mA to 3.0000 A, 20 Hz – 10 kHz 0.025 + 3 Frequency Resolution 012.000 Hz - 119.999 Hz 0.001 Hz 0.12000 kHz - 1.19999 kHz 0.00001 kHz 1.2000 kHz - 11.9999 kHz 0.0001 kHz 12.000 kHz - 119.999 kHz 0.001 kHz 0.12000 MHz - 1.19999 MHz 0.00001 MHz Temperature Accuracy (1 Year, 23 ºC ± 5 ºC) \-80.0 ºC to 150 ºC (5 kΩ thermistor probe) Probe accuracy + 0.2 ºC \-110.0 ºF to 300.0 ºF (5 kΩ thermistor probe) Probe accuracy + 0.4 ºF Capacitance Accuracy (1 Year, 23 ºC ± 5 ºC) ± (% of reading + % of range) 10.00 nF (100 nA) 1 + 1.5 100.0 nF (1 µA) 1 + 0.5 1.000 µF (1 µA) 1 + 0.5 10.00 µF (10 µA) 1 + 0.5 100.0 µF (100 µA) 1 + 0.5 1.000 mF (500 µA) 1 + 0.5 10.00 mF (1 mA) 2 + 0.5 Supplemental Measurement Characteristics DC voltage input resistance \> 10 GΩ (selectable 100 mV, 1 V ranges);
