It was developed for the instrument series LMG. The supply is done by a IEC inlet cord which must be connected to the MAK1. The load is connected by the fixed mounted cord. With the MAK1 you can measure the voltage (jacks U and U*). The current is also accessable (from I* to I). This jacks have to be connected to the jacks of the measuring instrument. The internal wiring is done so that the load is measured with correct current. This wiring is suited perfectly for the measurement of stand-by power. An important point is the safety. The MAK1 is in compliance with IEC61010-1 and was constructed for voltages up to 300V CAT III.
