Screen Layout Overview

When you access the Engine Speed Test, the screen is organized into three primary areas:

1. Status Line
This area displays real-time messages related to the diagnostic test process. It provides feedback on the current status of the test and any relevant alerts or notifications.

2. Instruction Area
Here, you’ll find step-by-step instructions guiding you through the diagnostic test. This section is particularly useful for new users who may need additional assistance.

3. Control Area
The control area is where the real action happens. It allows you to adjust the engine speed with precision. Key components include:

– Horizontal Slide Bar: This bar displays the range of engine speed parameters, with the current speed value indicated above it. Reference numbers are positioned on either side of the slide bar for your convenience, and a vertical slider shows the current value.

– Speed Adjustment Buttons: You have several options for adjusting engine speed:
– Decrease speed by one setting
– Decrease speed by 20 RPM
– Increase speed by 20 RPM
– Increase speed by one setting

Buttons and Their Functions

Understanding the buttons available on the Engine Speed Test screen is crucial for effective testing:

– Start: This button initiates the test, allowing you to manually manipulate engine speed using the arrow buttons beneath the slider bar. Once the test starts, this button will be disabled until the test is stopped.

– Begin Sweep: This function automatically varies the engine speed across the specified range. The sweeping action continues until you click the End Sweep button, making it a valuable feature for comprehensive testing.

– End Sweep: Pressing this button stops the automatic sweeping of engine speed, allowing you to maintain a specific speed for further analysis.

– Stop: This button concludes the test. It remains disabled until the test has started, ensuring that users cannot accidentally stop a test prematurely.
