Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters
bson:
I upgraded my 34465A to firmware 02.08 and discovered the DCV peak reading is very useful - I used it to quick check the performance of my HP 33120A function generator. Result: within spec, with only a 0.4mV output offset; less than 1/2 digit of the 1mV resolution offset setting. The peak is about 2 digits better, 1.39998V P-to-P for a 700mV setting. It's pretty neat that this DMM alone can be used to run through either the Q (quick) or P (performance) verifications since they're done at 1kHz/100Hz (depending on function), and this DMM is precise enough! Is it possible to measure DCV peak as a primary measurement? I poked around and couldn't find a way off hand...
I also noticed that holding down a key, including soft keys, for a couple of seconds brings up the help section for that function! Brilliant!

Yes, all new Keysight gear has that built in help function and it is really neat, also on the new scopes.
I don't think you can make the DC Peak to the primary measurement, at least I have not figured it out, if it should be possible
Yesterday, I compared my 34470A to a calibration lab just for fun and hooked it up to a calibrated Fluke 732A voltage standard.
The meter was warmed up for a few days in the cal lab at 23°C and the CAL button was pressed, before we took some measurements.
It was really nice to see 9.999,998 VDC on the 34470A and an almost flat line in the trend chart.
Actually the value written on the 732A was 9.999,999,99
The labs 3458A showed 10.000,000,4
So far, my 34470A seems to be a really reliable meter and I am very happy with it.
Lizerd:
How do I buy the 34465A with Digi option ?,
Do I have to request/order the digi "unlock code" from Keysight direct ?
Any one ordered a extra option for your 344xx ?
HighVoltage:
I ordered the 2M Reading Memory and the unlock code was sent to me by email
The fast DIG option is only available if you place it with your order.
Based on Keysight information, it is not user installable.

Really? Both the DIG and MEM options are just unlock codes (well license files) - there are no physical changes to the meter. Even the GPIB option is designed to be fitted by the end user. It would be mad of them to restrict you to buying an option only when your purchase the device.
