将该检测器插入汽车点烟器口,用于测量汽车电瓶工作状况，当打开汽车钥匙未启动发动机时,该检测器显示值正常在12V左右;当启动后汽车电瓶开始充电,该检测器显示值应为13V～15V之间，此时可放心使用或行驶。This battery meter is designed to measure the battery condition by plugging it in cigarette lighting socket. Beforeignitingthe engine, the meter shows 12 v on the screen. As the engine is ignited, 13 v ~ 15 v shouldappearon the screen, indicating it is in normal operating condition.当汽车发动不着时，该检测器显示值低于10V,则表示dianping电量严重不足，此时应及时充电或更换电瓶，车辆启动后将自动给电瓶充电，约一个小时后，即可正常使用电瓶启动车辆。If an engine fails to ignite, the meter will display 10 v or less on screen. It is then necessary to recharge, or replace the battery. After theengineruns about one hourchargingthe battery, it is back tooperatingcondition.特别说明:该电瓶电压检测器适用于12-24V汽车点烟器插口。该产品内置0.5A安全熔断管。若无显示时，请拧开检测器头部，检查玻璃熔断管是否熔断，若熔断，请更换相同规格的熔断管。将该检测器插入汽车点烟器口,用于测量汽车电瓶工作状况，当打开汽车钥匙未启动发动机时,该检测器显示值正常在12V左右;当启动后汽车电瓶开始充电,该检测器显示值应为13V～15V之间，此时可放心使用或行驶。This battery meter is designed to measure the battery condition by plugging it in cigarette lighting socket.
