HP E36xx- whats' up with color coding?!

(1/3) > >>

reagle:
Just bought several HP E3610/11s for work on ebay. All mid- 1990 vintage. Out of three, two (one of each kind) had both + and - binding posts color coded red. The third and newer 3611 has red, black, green as expected for +, -, GND.
Any ideas why would they do such a silly thing? These all came from different sellers and show no signs of damage or rework.
I love these units otherwise- very clean, easy to maintain and being HP all documentation is available.

Sometimes people rip off the color coded rings.  These are sold as spares. You cant get the green one anymore...
Probably replaced when the supply went in for calibration.

It's same on my E3615A. Also my 34401A has all connectors red. (all mid 90s, bought used in Japan)
Yes, it's silly.. why?  :-//

andersm:
My E3610A has the expected red, black and green binding posts. On the other hand the CC button is bright red as a previous owner mislaid the original one.

No its standard. My HP6002A also has red rings on the + and - connectors.
