Multilayer Shorts Locator TONEOHM 950

SKU: TONEOHM 950 Category: Tags: , , ,
  • Brand:POLAR
  • TONEOHM 950 採用革新性的向量層激發技術(VPS),提供快速和精確的指引,定位出PCB短路起點,使用者只需按照設備前面板的箭頭操作即可,非技術人員亦可操作。
  • 提供四種操作模式,涵蓋硬/軟PCB短路、蝕刻、錫橋、匯流排短路、去耦電容故障等問題。
  • 具有高敏感度的Track Resistance和Track Voltage模式。
  • 採用非破壞性方式追蹤短路至起點,無須切斷電路即可測量PCB銅線電流。
  • 採用非接觸式電流感應探棒,Track Current模式可輕鬆確定Vcc對地短路的位置,以及匯流排結構線路板中的故障。液晶螢幕清晰顯示相對測量值,並提供音頻信號,最高音頻代表短路。
  • 帶有電源或接地層的多層PCB上的短路,提供向量層激發技術故障定位法。
