Hi!
I changed the display of my Keithley 2015THD two months ago, and I don't know what to do with the old display.
I changed it with a good Solder Sucker desoldering pump, so with care, it is usable again.
It work very well at 50% of use or more, I think, so if someone in need I cand send it, only He or She must to pay postage.
I can receive the money by Paypal or bank transfer.
Regards
Manuel
