Temperature Compensated Pressure

When a tire heats up, the air pressure inside the tire can also increase. For example, a normal or required pressure at 64 °F (18 °C) may be 34 PSI or (2.34 Bar) and a normal pressure at 120 °F (49 °C) may be 39 PSI (2.70 Bar). Both pressure readings are correct at their respective temperatures. The amount of deviation from the required pressure at any temperature can be read by using the Pressure Deviation mode of this system. If at any time you are uncertain that the Actual Pressure reading on the gage is the correct tire pressure, switch to the Pressure Deviation (± ) readout. A blank display indicates that the reading on the display is the correct one. Any (+) or (-) value indicates the tire pressure is incorrect by that value. This value can then be used to correctly inflate the tire.

High Temperature Alert

  5. A new transmitter identification can be learned by inflating or deflating the tire by more than 3 PSI (0.20 Bar).
  6. This method must be carried out while the transmitters are in gage fill mode. This mode is entered for 15 minutes after the vehicle has been driven above 6 mph (10 kph). Each transmitter "learn operation" must be carried out at least 90 seconds apart. If it is not possible to complete the learn operation for all transmitters within 15 minutes, the vehicle must again be driven above 6 mph (10 kph) and then the process can be continued.
