isn't there any other option?
Plenty of people will argue that if you only touch mains once or twice per year and that if you double and triple check that the meter is on the right range
and the probes are connected to the right connectors then you'll survive. Wear work gloves and safety glasses, too.
Others might point out that you don't need to see the voltage reading of mains AC (it almost never reads the wrong value!) and you can test it more safely with a light bulb on a wire (with suitable probes, obviously) than with a multimeter. If it's a mains socket you want to test then just plug in a lamp instead.
You could also get something like a $20 ANENG 860B+. The main danger from multimeters is when they're on the current ranges, this meter has both the current inputs on
separate sockets so it takes a deliberate act to use them. So long as the probe is connected to the V/Ohms socket then you're reasonably safe. Remember to swap the leads back after you measure current to avoid accidents, and never, ever try to measure current of AC mains. If the leads are connected to one of the current input sockets and you're moving towards a mains wire then you're doing it very wrong.
do I really have to pay 50€ for a fluke
50€ is cheap around here.
