Any meter can be calibrated. Just compare the displayed values to the expected values and write down the numbers on a piece of paper.
Note that calibration does not involve any adjustments of the displayed value.

This multimeter may have one or more potentiometers for adjustments, but I doubt anyone bothered with a thorough calibration.

That meter, if it indeed like the DT830, would have just one (cheapo) VR.  I would adjust that against the 5V standard I have.

While some would sneer at cheapies like DT830B, but it has its use.  For $1-ish, it is rather decent for the money.  It holds to the nominal 1%-2% accuracy rather nicely, some range better than others of course...
