to 10 mA, where 2 mA correspond to 0 A out, and 10 mA
correspond to 400 A out.
The voltage drop across the test item is measured in the
meanwhile; the resistance is computed as the ratio of voltage
versus current.
The test is performed with high DC current in order to increase the
voltage drop to be measured; besides, the AC noise is filtered out.
The connection diagram is the following.
