MikroTik

I have rb750g
When i look in system/health it shows 2416.9V

when using terminal, it shows 1180V.

Does rb750g have voltage meter or this value is incorrect and not valid.

can you explain?

According to the spec sheet (http://routerboard.com/index.php?showProduct=90) it doesn't have a voltage monitor.

Yes, it seems so. but why then is some value? its just random?
