The 17B can be tweaked by doing its trimmers to significantly better accuracy. I have done it and I recommend it. 17B's thing is construction quality and meeting input overload spec. UNIT-T UT61E combines performance and a fair build, a natural choice for say $20-25 more than the 99. Vichy is slow, 61E is very fast.

Wrong! you are altering it's interpretation of the measurement in the particular circumstances you are in. Change the room temperature drastically and it will be off again. The idea of a guaranteed accuracy is that you know that within a stated varied range of temperature, humidity and whatever else the manufacturer cares to stipulate you are guaranteed a result to that level of accuracy.
Salas:
Yeah, right. I did it at a month or more ago 30C and today is 20C. The pic is now.
Simon:
and how do you know the exact voltage you measured to at least one order of magnitude better than the meter does ?
Salas:
It just follows my other 2 meters better in all cases. One is MS8218 which is good for accuracy. See Horton's test. No cal claims, works better practically, that's all. Shows nearer to my 61E mostly.
