The 3458A Multimeter is among the fastest, most flexible and accurate multimeters offered by HP, and includes such features as 8 digit resolution. DC voltage is from 0.1 V to 1000 V with and accuracy of 0.6 ppm, and AC voltage range is 10 mV to 1000 V with an accuracy of 100 ppm. Resistance range is from 10 ohms to 1 Gohms with an accuracy of 2.2 ppm. The 3458A also measures AC and DC current at high accuracy and has a built-in frequency counter to 10MHz. The HP 3458A multimeter shatters longstanding performance barriers of speed and accuracy on the production test floor, in research and development, and in the calibration lab.
