使用說明書Directions for use

u  儀表正確連接后，接通電源到額定電壓，此時綠色指示燈亮，儀表即處于監測狀態，指針指示值即為電網絕緣電阻值（自檢檔除外）。After the instrument is correctly connected, connect the power supply to the rated voltage, and the green indicator light will be on at this time, the instrument will be in the monitoring state, and the indicator value is the insulation resistance value of the power grid (excluding the self check file).

u  儀表在工作時報警設定開關應設置在所選定的報警值位置，報警值有八檔，分別為：0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.3MΩ、0.5MΩ、1MΩ。When the instrument is working, the alarm setting switch shall be set at the selected alarm value position, and the alarm value has seven gears, respectively：0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.3MΩ、0.5MΩ、1MΩ。

u  如需判別儀表工作是否正常時可進行自檢，將儀表后面開關設置在自檢檔位，儀表即進行自檢，儀表能進行正常自檢時指針應指示在0.01MΩ位置，同時報警紅燈點亮，報警輸出端有輸出。自檢完畢后必須將儀表恢復到正常報警檔位上。If it is necessary to judge whether the instrument works normally, self inspection can be carried out. Set the switch at the back of the instrument to the self inspection gear, and the instrument will carry out self inspection. When the instrument can carry out normal self inspection, the pointer shall indicate the position of 0.01MΩ, and the alarm red light will be on, and the alarm output terminal has output. After the self-test, the instrument must be restored to the normal alarm gear.

u  接岸電時，由于岸電系統為接地系統，儀表會發出誤報警，此時可將開關調整到“岸電”檔；儀表將指示在0.01MΩ位置，但輸出常開、常閉觸點不會發生轉換動作，無報警輸出。When connecting shore power, because the shore power system is a grounding system, the instrument will give false alarm, at this time, the switch can be adjusted to the "shore power" position; the instrument will indicate the position of 0.01MΩ, but the output normally open and normally closed contacts will not change action, and there is no alarm output.

Q72D-MΩA、AH-JDB-11外附變換器亦可單獨作為交流電網絕緣監測繼電器使用，而不用連接指示表頭（即5和6端子）（即5和6端子）。5和6號、7和8端子輸出信號為0-1mA電流信號，用于驅動外接指示儀表表頭；而該輸出電流信號與絕緣監測儀相對應關系。Q72D-MΩA、AH-JDB-11 external converter can also be used as insulation monitoring relay of AC power grid independently without connecting indicator heads (i.e. 5 and 6 terminals) (i.e. 5 and 6 terminals). The output signals of terminals 5 and 6, 7 and 8 are current signals of 0-1ma, which are used to drive the external indicator meter; and the output current signal corresponds to the insulation monitor.
