d to any range of insulation resistivity that the equipment comprising the two-surface tester allows. For the equipment specified herein, the maximum measurable resistance is 1200 k for the 10-A current setting and 12 000 k for the 1-A current setting; the maximum voltage for the test system is 12 V.
Repeat readings on the same set of two electrical steel laminations using different contact positions, as well as the testing of multiple laminations from the same lot of electrical steel, are recom
