The handheld device by transmitting low-frequency signal to wake-up sensors and collect sensor data which is transmitted by high-frequency from Sensor,then the received data (ID number / cell voltage / pressure / temperature) is displayed on the handheld device screen.Press launch/transmit button, it will transmit the received ID number by high-frequency to the host computer, such as the CAN receiving host or other TPMS receiver.
1,Handheld Device Operation Details
1) 、Short Press the B button 1Second, enter the car reading status (Figure 1).
2)、Long Press the B button 5 Seconds,enter the truck/bus reading status (Figure 2)
Notes: Press “B” Button to exit the reading state
3)、Read completion status (Figure 3)
Press A Button it will enter the next sensor id reading;
Press B Button it will back to the Main interface;
Press“TX”Button, it will transmit the sensor id shown through High Frequency
A、Press UP Button and DOWN Button Meanwhile for 2 Seconds,it will enter the specific tire wake-up and ID transmission interface,See below Figure 4
B、Input Password：FL、UP、RL、RR、DOWN、FR(Figure 5),after password input please Press A Button to confirm,it will enter production learning interface(Figure 6),in this interface tire number can be chosen from 1 to 30,Press UP Button is to add the tire number. If you are not familiar with this operation,sugguest choose tire number 01,or just contact us for more details.
C、Once you choose the related tire number,just Press A Buttion to confirm then it will enter the state of scanning interface(Figure 7),then take this handheld device close to tire valve(the position of sensor installation) and wait for about 10 Seconds,it will complete the work of this tire wake-up. Meanwhile the data scanned will be shown on the display screen,see Figure 8.
D、Above B Step,if you choose more than 1 tire learning mode,it will show the second tire scanning status 2 seconds later upon the completion of the first tire scanning.At this time just hold the handheld device close to the second tire to scan,similar action can be done to the next sensors.
E、When all the chosen tires waken up,it will show Figure 9,then Press A Button to transmit,then keep the handheld device with CAN Receiver or other TPMS devices within 5 Meters distance,this will help id matching,meanwhile it requires CAN Host and TPMS Receivers should be in the state of learning mode,otherwise it is unvalid.
F、the scanned sensors’ ID, Press the Transmit Button,the handheld device will tranmit sensor ID to the receiving units.If sensor id transmission completed,press DOWN Button it will start to transmit the next sensor ID until all sensors ID sending completed.(See Figure 10). If you want to resend sensor id,just press Transmit Button again. Press B Button to stop the sensor id transmission.
