You don't calibrate something like a fluke. You check it's calibration, if it is out you have several simple choices. Usually it involves throwing it away. I have served my stint as a metrology tech, calibrating oscopes, freq synthesizers, counters, and (oh yeah) DVMs. Usually anything that would make them go out of tolerance destroys them. The basic stuff, like using the ohms scale to measure voltage, hopfully the fuse will save the meter. It is part of the quality you are paying for.
I have to agree, the eBay deal has left the realm of a DVM. It's not even a good oscope, and I paid around $90 for a really good oscope last time I bought one. Resist impulse buying, it is not good for the credit scores. Just because a seller on eBay says it is a good deal doesn't mean squat.
