使用说明书Directions for use

仪器正确连接后，接通电源到额定电压，此时绿色指示灯亮，仪器即处于监测状态；当绝缘电阻值低于设定值时发出一报警信号，此时报警红灯点亮，报警输出端发生变化，常闭端转换成常开，常开端转换成常闭。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.

仪器在工作时报警设定开关应设置在所选定的报警值位置，报警值有十档，分别为：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）。

如需判别仪器工作是否正常时可进行自检，将仪器后面开关设置在自检档位，仪器即进行自检，此时报警红灯点亮，报警输出端发生变化，常闭端转换成常开，常开端转换成常闭；自检完毕后必须将仪器恢复到正常测量档位上。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.

接岸电时，由于岸电系统为接地系统，仪器会发出误报警，此时可将开关调整到“岸电”档；但输出常开、常闭触点不会发生转换动作，无报警输出。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.

外接指示表头（如需要时）即11和12端子。11和12号端子输出信号为0-1mA电流信号，用于驱动外接指示仪表；而该输出电流信号与绝缘监测仪相对应关系，显示仪表标牌显示∞-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).

仪器可用在各种船舶配电板、矿井、医疗、空调、充电桩、电站等各种IT配电电网系统上面使用。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.
