5. OPERATION
In normal operation the monitor continuously scrolls through and displays the pressure
and temperature of the tyres one by one. You can manually scroll through to any
particular tyre by using the + or - buttons. The system is accurate to 0.1bar (1.5psi), so a
difference of one or two psi between the tyres can safely be ignored.
The sensors check the pressure and temperature every six seconds. If the pressure is
falling, data is transmitted to the monitor immediately, but if the pressure is steady, data
is transmitted only every five minutes. This is to reduce power consumption and extend
the life of the sensor batteries.
If a sensor battery is low, or if a signal is not received from a sensor for a period of 60
minutes, an alert is issued.
5.1 Sleep mode
The monitor has a built in motion sensor that shuts it down into a sleep mode after about
ten minutes of no movement so it does not normally need to be turned off. Any vibration
like opening the vehicle door wakes it up again. In the sleep mode, the system continues
to check pressures once every hour, so that warning of any problem such as a slow
puncture overnight can be given to the driver as soon as it wakes up.
If the vehicle is to be unused for some time, we recommend turning the monitor off to
prevent battery drain.
5.2 Alerts
If there is a leak or if any tyre is outside the pre-defined values, it gives an alert:
Press any button to switch the alarm off. The red light will continue to flash until the
problem is corrected.
