#Display Area
The Display Area has three columns:
  • Cylinder/Description – Lists the available cylinder numbers.

  • Test Result – Displays Open, Short or OK after the test has completed.

The Buttons available on Test screen are:
  • Change – Click to change the state of the cylinder. Changing the state of the cylinder allows solenoid troubleshooting by "cutting out" and subsequently repowering an individual cylinder.
  • Power All – Click to return all cylinders to the powered, or active, state.
  • Cutout All – Click to change the state of all cylinders to cutout.
  • Start – Click to begin the test. Once clicked, this button is disabled until the test is stopped.
