Hi: I have selected the Lm7905 and lm7909 in simulation mode like this:  Which could be seen here: [https://easyeda\.com/editor\#mode=sim\,id=\|1f8d2e91e71e4daeba70b25b2bc15fa6\|4b4839cf2c8c497b981f4f62a1a04f0a\|310de4f753f3458f88e92d9f05ab0594](https://easyeda.com/editor#mode=sim,id=%7C1f8d2e91e71e4daeba70b25b2bc15fa6%7C4b4839cf2c8c497b981f4f62a1a04f0a%7C310de4f753f3458f88e92d9f05ab0594) So as you could see the multi meters have the same 5V and don't show -5V or -9V?
