Truck TPMS 1. Components: 1 Display 1 Receiver Module 6 external Sensors 2 antenna 1 link cable. 2. Alarm Function (1) High Pressure Alarm: The pressure is higher than standard about 40% (2) Leakage alarm: The pressure decrease over 0.4Bar in 20 seconds (3) Low pressure alarm: The pressure is lower than standard about 25% (4) High temperature alarm: The temperature of tire is over the threshold (5) Low power of sensor alarm: The power of any sensor is less than 2.4v (6) No signal alarm: Missing some sensors message over 20 minutes after it start to work. 3. Operating Functions (1) Pressure Unit setting: change Bar to PSI (pre-set unit is bar) (2) Temperature Unit setting : change C to F (pre-set unit is C) (3) Standard pressure setting: increase or decrease (pre-set value is cold tire pressure 2.4 Bar) (4) High temperature alarm threshold setting: pre-set threshold is 80C (5) Set up sensor: learn new sensor ID code when replace sensor (6) Exchage tires position: when mismatch sensor to tires, change position on display. 4. Product Features (1) Real time monitoring (2) Display pressure of 6 tires on one screen. (3) Display powered by vehicle battery. (4) Sensor battery life can be uesed at least 6 years. (5) Alarm with beep sound and display screen red light flashing. (6) Display show which tire is abnormal. 5.
