Your red probe is in the wrong plug on the meter, it should be in VΩmA NOT 10A DC, That is for measuring current and would put a short on what ever voltage you are trying to measure.
The dial is in the correct place for measuring up to 1000 volts, if the voltage is below 200 volts you can use the 200 volt range
