使用说明书Directions for use
u 仪表正确连接后，接通电源到额定电压，此时绿色指示灯亮，仪表即处于监测状态，指针指示值即为电网绝缘电阻值（自检档除外）。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 仪表在工作时报警设定开关应设置在所选定的报警值位置，报警值有八档，分别为：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 如需判别仪表工作是否正常时可进行自检，将仪表后面开关设置在自检档位，仪表即进行自检，仪表能进行正常自检时指针应指示在0.01MΩ位置，同时报警红灯点亮，报警输出端有输出。自检完毕后必须将仪表恢复到正常报警档位上。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 接岸电时，由于岸电系统为接地系统，仪表会发出误报警，此时可将开关调整到“岸电”档；仪表将指示在0.01MΩ位置，但输出常开、常闭触点不会发生转换动作，无报警输出。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外附变换器亦可单独作为交流电网绝缘监测继电器使用，而不用连接指示表头（即5和6端子）（即5和6端子）。5和6号、7和8端子输出信号为0-1mA电流信号，用于驱动外接指示仪表表头；而该输出电流信号与绝缘监测仪相对应关系。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.
