The max. voltage rating for 3446xA and 34470A was changed in the specification recently, downgraded to 600V DC / 440V AC only.
What's the reason behind?
Can I still use the full 1000V DC or 750V AC, as imprinted on my 1 1/2 years old 34465A?
Will Keysight fix all units, to bring them to full specification again?
