It is recommend to test the sensor first. You could take off the sensor from your tire to see
if the machine alarm.
1) If the monitor begins beeping, it means your sensor is in normal operation. Then you
could try to re-install the sensor. If it still does not work, maybe the sensor lacks battery
power. Then you could try another battery again. And here I would like to provide a
change-battery video to help you. The video link is as follows:

2) If it doesn’t alarm, it also may mean that your sensor lacks battery power.
You could use another new battery to try again. The battery-change video is mentioned
above, you could refer to it.
4. It is normal for the tire pressure monitor to measure the tire pressure with a certain
degree of accuracy. (When you find that its measurement result is different from your tire
pressure gauge.)
---IF THE SENSOR IS NOT IN THE NORMAL OPERATION---
If you find the tire pressure that the monitor displays is not accurate, there are two
different possible reasons that could explain this issue.
1) The feature of needing some minutes to update the data.
Our TPMS will receive real-time signals. In general, the display will update every 5
minutes. You could wait a minute and then confirm if the reading is correct.
2) Different measuring tools may cause some deviation in the normal range (if you use a
tire pressure gauge to compare). The theory of measure between two devices is different.
Here is the operation theory of the TPMS and of the tire pressure gauge.
The TPMS monitors the tire pressure and the temperature referring to their variations per
unit time. And the tire pressure gauge monitors the tire pressure by getting the
instantaneous data. So it is normal that when you use two different measuring tools, you
would get two data which has a little deviation. But the two different data are also
referenceable.

THE TIRE PRESSURE ACCURATELY---
