This is nonsense. Look at the specification sheet packed with the meter. Even the cheapest DVM has accuracy greater than 5% accross the audio spectrum and it's best to measure in the center of the desired spectrum. You can additionally check the readings at 20 and 20K hz if you like, but 1K is a standard refernce for a reason.
