I have a batch of bench meter and TM500 meters I need to check in and calibrate and adjust for the lab to bring them in to spec. I have a repaired Fluke 5200A and the 5205 amp to go with it so I think I have AC covered. But I need something for DC and resistance. Don’t mind spending a bit of money if it is on something fluke or similar quality. Is there a multi-unit that does DC and resistance? Might also need current at some point as well but the primary focus is DC/AC/resistance.
