I`m noob for at last 56 years, is it a problem? Why do You discriminate noobs?

I was referring to his post count, all 3 posts were in this topic.

Hello. I have one question related to this multimeter (and other multimeters in general) :
When measuring voltage (eg : 220V AC) with probes endings plugged into socket 2 and 3 (the last two sockets, starting from left), is there safe rotary switch positions other than "V" and "mV" ?. AFAIK "A"and "mA" positions are a big no-no (since it's basically a short-circuit) but what about others ? (eg : ohms measurement or continuity test) ?

No.
(and I have doubts about the mV position)
nb. Even if the switch is on 'V' the leads can still be in an unsafe position... be sure to triple-check everything.

Hello guys :)
So, anyway, I've stupidly managed to burn input divider 5MΩ resistor (R30) on my AN870 by trying to measure output of a (unloaded) CCFL backlight driver |O.
Since 5MΩ is not really a standard value, and as far as I've managed to find out, this resistor is MELF 0.25%, the best I could manage to find locally was two in parallel 10MΩ 1% metal film resistors. Voltage measurement works now, but it is showing a little bit low. Before it would be almost bang on 10.000V when I feed it AD584 10V voltage reference. Now it reads something like 9.954.
Question is: will I ever be able to get back the accuracy with 1% resistors (can't really find any better locally), should i try calibration procedure, or should I scrap the multimeter?
