inlets and 3 outlets for power supply (for decoupling) and two measurement channels (RHM1 and RHM2), each made up of two injection (INJ) and reading (SENSE) terminals.<br \/><br \/>The measurement requires injection on the load and reading in two possible points: on the load (measurement at 4 wires)<br \/>or directly on the instrument (measurement at 2 wires).<br \/>The choice of one measurement or another depends on the type of precision you want to have, as well as the connections available. In the case of a 2-wire measurement, the value to be read also includes the resistance of the connection cables, and in the case of a 4-wire measurement, the value to be read is only that of the load.<br \/><br \/>1.
