Fluke 8020A banana size?

[rich]

Does the 8020A use 4mm or 2mm banana sockets as standard for test lead connection?

I've owned one for over 15 years which is fully rebranded with the logo of a telecoms corporation and uses 2mm sockets. So I'm wondering if that was the norm back then or if it was a customisation for the rebadged version.

If anyone is interested, the pcb has Fluke logo and marked © 1979, RevP 802XA-3001.

Thanks
