Troubleshooting equipment故障诊断设备

1. Voltmeter and test light1. 电压表及测试灯

◊

You can check the status of the circuit and check for voltage with a test light or voltmeter. The test light consists of a pair of wires and a 12 V bulb. During inspection, one wire is grounded and the other wire is connected to a certain measuring point. If the bulb lights up, there is power supply at the measuring point.可以用测试灯或电压表检查电路状态，检查有无电压，试灯由一对导线和12 V 灯泡组成。检查时，一根导线接地，另一根导线连接在某个测量点上。如果灯泡点亮，说明测量点上有电源供应。

Warning:警告：

♦

Pure electric vehicles contain high voltage. Improper operation during use or maintenance may lead to safety accidents such as electric leakage and electric shock, causing harm to the human body or the vehicle. Therefore, be sure to perform inspections or repairs in the correct order.纯电动车辆含有高电压，使用或维修时操作不当，可能会导致漏电、触电等安全事故，对人体或车辆造成危害。因此，一定要按照正确的顺序进行检查或维修。

♦

The voltmeter is used in the same way as the test lamp, except that the voltmeter can also display the current voltage. When using a voltmeter to detect voltage, a high-impedance voltmeter should be used. When there is a loose connection in the wire connection, the voltage displayed by the voltmeter is normal, but this voltage cannot successfully drive the load to operate normally.电压表的使用方法与测试灯相同，不同的是电压表还能显示当前电压的大小。在使用电压表检测电压时，应该使用高阻抗的电压表，在导线连接存在虚接的情况下电压表显示的电压正常，但该电压并不能成功带动负载正常工作。

2. Test lamp and resistance meter with own power supply2. 自带电源的测试灯及电阻表

◊

Use a test light or ohmmeter with its own 12 V power source to check for continuity. The test light with its own power supply consists of a light bulb, a 12V battery and two wires. The light bulb lights up when the two wires are connected. Before testing, disconnect the negative 12V battery lead and pull out the fuse of the circuit. During inspection, if the test light lights up normally, the circuit is normally connected.用自带12 V电源的测试灯或电阻表检查回路是否导通。自带电源的测试灯由灯泡、电池和两根导线组成，两根导线相连接时灯泡亮。检测前，应断开蓄电池负极导线并拔出该电路的保险丝。检查时，如果测试灯正常点亮，则线路是正常导通的。

Warning:警告：

♦

When checking the module circuit, it is forbidden to use the test lamp with its own power supply, otherwise the internal circuit of the module will be damaged. A digital resistance meter with an internal resistance of 10 MΩ or higher must be used to check. The use of the resistance meter is the same as the voltmeter, but the resistance meter can display the current resistance value. The lower the resistance displayed, the better the conduction.检查模块电路时，禁止使用自带电源的测试灯，否则会损坏模块的内部电路。必须使用10 MΩ 或内阻更高的数字电阻表来检查。电阻表的使用方法与电压表相同，但电阻表能显示当前的电阻值，显示的电阻越低表示导通越良好。

3. Fused jumper wires3. 带保险丝的跨接线

◊

When checking open loop (line break) circuits, jumper wires are needed to identify the break point. A jumper wire is a tool used in series with the conductor under test.在检查开环( 线路断路) 电路时需要使用跨接线来确定断路点。跨接线是与被测导线串联使用的工具。

Warning:警告：

♦

In order to protect the circuit being tested, it is prohibited to use a fuse with a larger capacity than the rated capacity of the circuit to check the relevant circuit. It is prohibited to use jumpers instead of input or output signals when the module is connected in the line.为了保护被检测电路，禁止使用比电路额定容量大的保险丝检查相关电路。禁止模块连接在线路中的情况下使用跨接线代替输入或输出信号。
