A look at the Uni-T UT210E
Martin72:
No, the rotary switch was on 2A position.
I took a look in the programmer, the supply for the eeprom seems to be controlled by the µC - which make sense because of 3.3/5V type switching.
And so it seems on the scope screen, it raises to 3.3V, for a short moment to 5V, then falling and this repetively.
Maybe the time the eeprom was supplied was too short, I don´t know.
I bought the 2010 because I want to read out an 93C86.
And this failed too, but in a"funnier way" :
You click reading and the message appear, reading complete but you see nothing except FF.
Disconnect it from the eeprom, it does the same...
Edit:
I´ll take the programmer at work on monday, then programming an 93CXX with our programmer to make sure it IS programmed and after this I try to read it out with mine.
If this fails, I know the programmer is defective... :P

How are you powering the meter? Do you have the battery pack clipped in?
Martin72:
No,
In this video it wasn´t powered also:
But a good hint, maybe it needs internal supply because THIS programmer couldn´t deliver it.
Will check this.

Another possible clue:

If you scroll down, a few posts following I wasn't using an external supply but I wonder if you are right that your's doesn't have enough drive. I never tried using the header but rather just clipped onto the IC.
Martin72:
Hi,
External power given, still can´t reading the chip.
Final try will be with the pullups.
