The Reservoir Recovery Test is used to measure the time it takes the Service Reservoir to recover to 100 psi if it drops below 85 psi.
See Mode, Test and Vehicle
Specific Equipment Connection
A Pressure Sensor should be installed at the main air supply reservoir and connected as Sensor #1. Insure that the sensor is shown on the main display of the computer. Other sensors may be connected anywhere on the vehicle, as desired.
Insure that all reservoirs have been drained before conducting this test. Installing a sensor in a drain port may damage the sensor with moisture, sludge or other contaminants.
Running the test
The test is started when any of the connected sensors measures a pressure moving up from 84 to 85 psi. If all pressures are initially above 85 psi, the test will not start until at least one sensor has dropped below 85 psi and begins to recover above 85 psi.
The pressure on each attached sensor is recorded as the Begin pressure and a timer appears in the on-screen Control Panel. The test will continue to run until all sensors have recorded 100 psi or 59.99 seconds have elapsed since the test began. The on-screen Control Panel will display a timer showing the running time of the test.
After all pressures being measured have reached 100 psi, the time since the start of the test is recorded for each sensor and is displayed in the row End pressure.
The test can be reset to run again by clicking the RESET button in the on-screen Control Panel.
