Then pretty easy to verify if for instance you want 100mv on the 220 range, just use your 720 to bounce the emf against your 732, same for all ranges.

For the 220-1000 use the same technich just do back to back so no current flow.... ie null out with a good digital meter or better something like a fluke 745A or the newer tegam null meter, ie. null everything against your 732A using ratio devices
