Or....if it's really just once a year then get something cheap and take your chances. Triple check it's in the AC mode. Don't hold the meter in your hand, hold just the probes.
(hold both probes in the same hand if possible.
Remember to never do it alone (so the other person can call an ambulance).
Wear safety goggles, big gloves, rubber boots, a thick woolen coat... put a mattress on the floor behind you. Remember to record it all on youtube so we can laugh.
Most electricians I know (mind that mean age is 50) use cheapest clamp meter they could find at local hardware store and by some miracle are still alive and doing their job just fine. And before advent of DMMs they used lightbulb with two wires and they also weren't being electrocuted on a daily basis. Heck, I couldn't even kill a 2.5$ "QC PASSED" brand DMM with an insulation tester that goes to 1.5 kV, only injury was my hand being sore after rotating that stupid crank for too long. I don't know where does the assumption that every cheap meter blows after getting close to mains socket come from. Well, ohms range circuit on a cheapie won't probably be happy after getting 230 V to the test leads, but analog meters also die pretty horribly after trying to pull such a stunt and nobody considers them "unsafe".
