Back in Black - the previous model did not meet the EU RoHS compliance requirements and was therefore discontinued. Keysight then completely redesigned the 3458A. With regard to RoHS compliance, Keysight has extensively revised all of its circuit boards for the 3458A. The revised 3458A is 100% compatible with your existing 3458A.
The multimeter 3458A is characterized by an 8½-digit display, an accuracy of 0.0008% with DCV (optional 0.0004%), maximum stability of 8ppm per year, combined with a very fast measuring speed with very high, absolute measuring accuracy . That is why the 3458A is the standard in calibration and calibration laboratories, in production fields and development laboratories around the world.
The 3458A is used for high-precision DC and AC voltage measurements and DC current measurements. Applications can be found in test benches for various tasks in meteorological institutes, development laboratories and production, where the high measuring speed is also an advantage.
