Are you willing to open your U1273AX?

Hello!
I am very curious as to why there are two versions of firmware on Keysight support website.

Could someone brave check their firmware version on their meter (turn on meter, go to Setup, Menu 5 top line is REVISION).
Here is the brave part - if it is 4.01 or 4.02, could you please open up your meter, remove the PCB, unscrew the 4 screws holding the OLED, remove the OLED, and check the version of the OLED on that meter? On flex cable of the OLED screen it will say SSDxxxxx version.

Disclaimer - I am pretty sure by doing that you will void warranty of the meter. So if it is still under warranty, please do not do it unless you don't care for it.

Thanks in advance!!

I am also interested to find out if anyone who bought this meter recently - is the OLED screen still SSD1303??
onesystem:
I take it there is no one who is up to opening the meter, OR

no one really uses them anymore...

Has anyone bought the U1273A or U1273AX in the last 4 years?
TheSteve:
Nobody who wants a meter that lasts anyways.
onesystem:
I understand. The OLED screen does go bad.
There might be a solution to that though, where SSD1309 OLED could be used without the need of designing a circuit to translate comm between meter and it.
Having to replace a $10.00 - $15.00 screen once every 3-4-5 years is not that bad for the functions and quality of the meter.

The U1272 is a great meter, the best handheld for an electronic engineer IMHO.
The U1273 adds no value, just trouble. And it's useless outdoors in daylight, apparently.
