儀器正確連接后，接通電源到額定電壓，此時綠色指示燈亮，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，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。After the instrument is correctly connected, power on to the rated voltage, then the green indicator light is on, the instrument is in the monitoring state; When the insulation resistance value is lower than the set value, an alarm signal is issued. At this time, the alarm red light is on, and the alarm output end changes. The normally closed end is converted to normally open, and the normally started is converted to normally closed.

儀器在工作時報警設定開關應設置在所選定的報警值位置，報警值有十檔，分別為：0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.5MΩ、1MΩ、（1.5MΩ、2MΩ、5MΩ）。When the instrument is in operation, the alarm setting switch should be set at the selected alarm value. The alarm value has ten levels, which are respectively:0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.5MΩ、1MΩ、（（1.5MΩ、2MΩ、5MΩ）。

如需判別儀器工作是否正常時可進行自檢，將儀器后面開關設置在自檢檔位，儀器即進行自檢，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。for identifying whether instruments work normally when the self-checking, can be put behind the instrument switch Settings in self-inspection gear, instrument is introspected, warning red light light up, at this time change alarm output end, into a normally open normally closed end, often beginning into a normally closed; After the self-test, the instrument must be restored to the normal measuring gear.

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（如需要時）即11和12端子。11和12號端子輸出信號為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）。external instructions header (if needed) 11 and 12 terminals. The output signals of terminals 11 and 12 are 0-1mA current signals, which are used to drive the external indicator instrument; And the output current signal and corresponding insulation monitor, display instrument panels show up - 0.2-0MΩ (0-1 ma).

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.
