Ki jan yo lokalize fil ak kab Breakpoints lè l sèvi avèk yon miltimèt dijital
Apa de mezire paramèt debaz tankou vòltaj, aktyèl, rezistans, kapasite ak tranzistò, yon miltimèt dijital kapab tou itilize kreyativite pou elaji kapasite li pou aplikasyon milti-bi. Dekri anba a se metòd pou idantifye pwen rupture nan fil ak câbles ak yon miltimèt dijital.
When an internal break occurs within a cable, the exact location of the fracture is difficult to pinpoint due to the outer insulating sheath. A digital multimeter can resolve this problem easily. The detailed procedure is as follows: Connect one end of the broken wire (cable) to the 220 V AC live conductor, and leave the opposite end open‑circuited. Set the digital multimeter to the AC 2 V range. Starting from the live‑wire connection end of the wire (cable), grip the tip of the black probe with one hand, and slide the red probe slowly along the cable's outer insulation. The displayed voltage reading will be around 0.445 V (measured on a DT890D multimeter). When the red probe reaches a certain point, the reading drops abruptly to a few hundredths of a volt (approximately one‑tenth of the original value). The cable breakpoint lies roughly 15 cm toward the live‑wire connection side from this position.
