Long lines (wires), when measured voltage changes are very slow (eg, analog temperature sensors, lighting, humidity), should be filtered by ceramic capacitors at the entrance to the measuring system, installed between each input and ground .
Muda mrefu mistari (nyaya), wakati kipimo mabadiliko voltage ni polepole sana (kwa mfano, Analog joto sensorer, taa, unyevu), lazima Filtered na capacitors kauri katika mlango wa mfumo wa kupimia, imewekwa kati ya kila pembejeo na ardhi .
