WOW! Every model railroader needs this tool! With our mXion POLI it is now finally possible to have correct wiring for booster areas, reversing loops and various. to do other applications without constantly having to wonder whether the polarity is correct and the wiring is correct. The POLI determines the signal type (DC, AC, DCC or Märklin-Motorola (MM for short)) and also the signal polarity. This is particularly important with MM as it is not a symmetrical signal. It is also important to know what polarity the connection of individual sections in boosters or segment areas has, otherwise massive short circuits will occur. The POLI can be used to determine what the phase alignment of the track voltage is and whether the booster section needs to be connected correctly or with the polarity.
