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??
