Real or fake: Keithley DMM6500 on AliExpress

[Zucca]

Definitely go for IPS if you can, DMM6500 uses a COTS display with early units being TN, later IPS, the later ones look much nicer.

How do I tell if my DMM7510

Five-inch capacitive touch, color thin-film-transistor (TFT) WVGA (800×480) with LED backlight.

 has TN or IPS?

ah:

Not the same LCD model but most likely should work just fine as it uses pretty standard LCD, worth a try for just $9. https://www.aliexpress.com/item/1005005199455421.html

I can confirm that IPS LCD from Aliexpress works fine in 34461A. Since it costs peanuts, I thought it wasn't a bad idea to upgrade TN display in my early 34461A. Good brightness, viewing angles, contrast.

you should report it in a new thread "TN display upgrade to IPS in TE"

Thank you for this confirmation that this specific part is compatible.  I've bought 2 of them so I can swap 1 and have a spare.  We'll see how it goes.

I have problems... I updated the firmware. The battery is fine... what could it be?
