@PA4TIM: I know you for a long time, including the forum circuit online and I know you have no experience or qualifications to talk about safety in high energy circuits.
You are radio amateur, collector, passionate to the extreme by the electronics, a brilliant electronic self-taught people who lives for and by the electronics.
You talk about security thinking about the measures you do every day at home, in your workshop ...... And here I agree with you, I too have an AVO 8 and there is no problem to use it in a 230V circuit protected by a 25A circuit breaker .... These are low energy circuits with a short circuit current of 2000 to max 5000A
In case of an accidental short circuit, there is nothing more serious to expect.
In the discussion, there was talk of using such devices on high energy installations with short circuit currents of tens of thousands of amperes.
In these cases, the consequences of a short circuit are quite different, they can even be lethal. (see videos)
The advice never to use analog multimeters to make measurements on high-energy circuits is a generalization based on the observation that 99% of the analog multimeters currently still existing are either old cat unclassified devices or the worst crap multimeters sold at 10 bucks.
There are indeed some modern analog multimeters duly protected and cat rated, but they are a tiny part of what still exist.
Of course, you can only trust in in high quality and famous brand as well for analog multimeters than dmm.
EDIT: As BD139 pointed out, using a measuring device that does not have a cat classification or does not have the correct cat for the work you are doing is a serious professional misconduct and the insurance might not intervene in case of accident.
EDIT 2: Let us remember that pure analog multimeters (without electronic circuit added) are NEVER AC true rms even if they cost more than 400 bucks and are useless for AC measurements with PWM inverters.
