[Highspark24/7]

Hi all looking to get into ev installing on both commercial and domestic soon and have been looking at an ev stand alone Megger tester as I have 4x fluke 1651 52c 53 53c also a Megger 1721 multi function testers. Would it possible to do a 12ma b type on half times would that do for the 6ma test as my fluke 1653c and 1721 could both do that test
