2A95C-TPS-LEExternal Tire Pressure Sensor (BLE)

Battery Life（电池寿命） Battery Replacement（电池更换） Name（名称）External Tire Pressure Sensor（BLE）/外置胎压传感器（蓝牙版） 1year/1 年 MPack0580 CR 1632 22.5 x 15 mm 0.01 Bar 0-8 Bar Size Parameters（尺寸参数） Measurement Accuracy（测量精度） Pressure Measurement Range （压力测量范围） Product Overview（产品概述） Package Contents（产品清单） Product Installation（产品安装） Product Specifications（产品规格） Install the tire pressure sensor onto the tire valve to complete the installation. Once connected to the onboard display unit, the tire pressure and tire temperature will be shown in real time, helping ensure safer driving. 将胎压传感器安装在轮胎阀上，即可完成安装。通过与车机连接，轮胎气压和轮胎温度实时显示车机上，有助于安全行驶。 External Sensors ×2 外置传感器 ×2 Anti-theft Nuts ×2 防盗螺母 ×2 Wrench ×1 扳手 ×1 ① Remove the valve caps from the front and rear wheels, then screw the included anti-theft nuts onto the front and rear tire valves. 将前后轮气嘴帽拆出，并将胎压传感器附赠防盗螺 母分别拧入前后轮气门。 进入胎压应用页，点击配对按钮进行配对。 ② Open the tire pressure app and tap the Pair button to start pairing. 当前轮数据窗口闪烁时，将任意一个胎压传感器拧入前轮气嘴，视窗出现数值即完成配对，并用附赠扳手逆时针拧 紧防盗螺母固定；当后轮数据窗口闪烁时，再将另一传感器拧入后轮气嘴，出现数值即完成配对。 ③ When the front wheel data window flashes, screw any one of the tire pressure sensors onto the front valve. Once a value appears on the display, pairing is complete—then use the included wrench to tighten the anti-theft nut counterclockwise. When the rear wheel data window flashes, screw the other sensor onto the rear valve; once a value appears, pairing is complete. 配对前请勿提前将传感器拧入气门嘴。 安装完成后请检查是否存在漏气情况。 传感器发射信号的逻辑为当感受到压力变化或、车辆车轮转动，配对时可能存在压力检测非实际压力的情况，以 30KM/H以上时速骑行一段距离即可读取准确胎压。 配对前传感器不区分，配对后需要区分前后轮，如重新进行配对无需区分前后轮。 4.Please check for air leaks after installation. 3.There may be situations where pressure detection does not accuratelyreflect the actual pressure when paired. Accurate tire pressure readingscan be obtained by riding a certain distance at a speed of 30 km/h orabove. 2.Before pairing, the sensors do not need to distinguish front from rearwheels; After pairing, the sensors need to distinguish front from rearwheels;If you pair again, the sensors do not need to distinguish frontfrom rear wheels. 1.Do not screw the sensor into the valve before pairing.
