A good, known accurate DVM is an asset to any station. Use it to determine if the others are accurate. There are several good brands available. A DVM that is not accurate is worse than no DVM at all.
My choice of many years ago is my Fluke 77. After I tapped it with too much voltage, I sent it to Fluke for repair and calibration. I am confident when I make a measurement it is accurate without question.
