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，具体报警值档位见背面展示图。用户有其他要求时可在订货时注明。When the instrument is working, the alarm setting switch shall be set at the selected alarm value position. See the back display diagram for the specific alarm value position. Other requirements of users can be noted when ordering.
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10KΩ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 10KΩ, 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.
