I have never said that .... if you are doing measurements on a high energy circuit, you must use at least a dmm catIII 600 or 1000V or cat IV of a brand deemed serious, not a crap DT830 or other no name multimeter . ..
So, why don't you say like that from the beginning? "if you are doing measurements on a high energy circuit, you must use at least a dmm catIII 600 or 1000V or cat IV of a brand deemed serious", I'd only change "must" to "should"... and then fully agree with you. The form of result presentation (analog/digital) has nothing to do with the meter safety, so your previous statement that "if you are doing measurements on a high energy circuit, you must not use analog multimeter" is logically wrong. The reason for not using a particular multimeter on a high energy circuit is it's inadequate/unsafe construction (and thus the lack of CAT rating), not the analog type of "display".
I really hate when someone forbids me to do something, giving no logical explanation why, or giving an explanation that is not logical. It is ok for religious beliefs, but not for law, nor for technical rules. I know that Microsoft has their official "Evangelists", but I find this name in this particular context to be a stupidity. But in fact they do create a religion instead of technical consulting - they show Microsoft technology to their (often "technically impaired") clients and trying to convince that it is the best one, and they should use it and only it. I find it really upsetting, that people more and more often obey rules or follow instructions, not caring about the reasons behind them. It is like: someone told me that it should be done like this, so I'm always doing it like this, and I'm teaching other to do the same... I don't care why I should do it like this or if I could do it better/easier way. Maybe I'm wrong, but for me, you sound like them.
On a forum, my advice is that you must be safe, not you should be safe .... because safety is not an option ....
But of course, as I explained, it's not an order, it is impossible to give orders on a forum .... You do what you want, if you want to take risks, sincerely, I do not care .... But do not advise to others to do it.
When we talk about an analog multimeter, we are not referring to just the display, but to the whole multimeter, including its construction ... Since 99.99% of analog multimeters are unprotected, dangerous and have no cat classification, it is perfectly logical to say: never use them to make measurements on high energy circuits.
You only make a futile discussion, quibbling for a word you do not like ...
