           使用說明書Directions for use

          儀器正確連接后,接通電源到額定電壓,工作指示燈亮,儀器即處于監測狀態;當絕緣電阻值低于設定值時發出一報警信號。After the instrument is connected correctly, the power supply is connected to the rated voltage, and the work indicator light is on, the instrument is in the monitoring state; An alarm signal is sent when the insulation resistance value falls below the set value.

          如需判別儀器工作是否正常時可進行自檢,此時報警紅燈點亮,報警輸出端發生變化,常閉端轉換成常開,常開端轉換成常閉;自檢完畢后必須將儀器恢復到正常測量檔位上。If it is necessary to determine whether the instrument works normally, self-check can be carried out. At this time, the alarm red light is lit, the alarm output end changes, the normally closed end is converted to normally open, and the normally open beginning is converted to normally closed. The instrument must be returned to the normal measuring gear after self - check.

          接岸電時,由于岸電系統為接地系統,儀器會發出誤報警,此時可將開關調整到“岸電”檔;但輸出常開、常閉觸點不會發生轉換動作,無報警輸出。When answering ? shore power, due to shore power system for the grounding system, instruments have a false alarm, the switch can be adjusted to "shore power"; But the output normally open and normally closed contacts will not have conversion action, no alarm output.

          外接指示表頭輸出信號為0-1mA電流信號,用于驅動外接指示儀表;而該輸出電流信號與絕緣監測儀相對應關系,顯示儀表標牌顯示∞-0.2-0MΩ(0-1mA)。The output signal of the external indicator head is 0-1mA current signal, which is used to drive the external indicator meter; The output current signal is corresponding to the insulation monitor, and the display instrument label shows ∞-0.2-0MΩ (0-1mA).

          儀器可用在各種船舶配電板、礦井、醫療、空調、充電樁、電站等各種IT配電電網系統上面使用。The instrument can be used in all kinds of SHIP switchboard, mine, medical treatment, air conditioning, charging pile, power station and other IT power distribution system.
