Hi
I lately measured the frequency of the output of a UPS with 220V output. I was adjusting the frequency to 50Hz... the multimeter measures frequency with range 0-10MHz. That was the last time I used the multimeter.
Now I found that the multimeter is not measuring anything right.... The voltage, current, resistance, capacitance... the multimeter even gives values without connecting it to anything, for example when I put the range switch at 1000V AC, it gives me some reading about 200V!
I opened the multimeter and found the fuse broken, I changed it, and the problem still the same...
Here is a link to the multimeter I am using with it's specifications

Any Ideas?
