Resistor 7 there looks smoked. I don't know exactly what it does, but I expect there's at least one setting that isn't working quite right. Not trying to be the bearer of bad news, but you may want to try to find a way to test the meters functions under known conditions before assuming it works fine.
If you've done that on all the settings then you may be good, but it makes me uncomfortable looking at it.
Me?
