help oldish multimeter

450V with a fair current behind it is dangerous, though it's not like mains, with very high current available that could cause arc flash. So look at the probes carefully and possibly buy a higher quality set. Also attach the probes before switching on where possible. It's all too easy for a probe to slip with unpleasant results. Many years ago I got bitten by 1200V DC, mains derived, from a 'scope I was probing. It ******** hurt. The problem was a probe whose insulation wasn't as good as I thought it was.

I'm sure I don't need to tell you all this but a safety reminder doesn't hurt. Unlike a 450V HT belt.
