Selecting Test

Selection of DATA, INPUTS, or OUTPUTS test types will result in first available test being displayed. If message, "---" ever appears, it means that test is not allowed with engine running. Shut engine off and repeat sequence.

Last 4 characters of display will contain a test code to identify selection. First 2 of these characters are letters which identify system and test type, while last 2 characters numerically identify test.

When selecting a specific test there are 3 available actions to be taken:

• Pressing OFF button will stop test selection process and return display to next available test type for selected system.
• Pressing LO fan button will display next smaller test number for selected test type.
• Pressing HI fan button will display next larger test number for selected test type.
