Test Readings

Scope
The following pages give readings and instructions for measuring the signals and voltage levels at the main instrument unit and its control module.

Remember:
- Note the test condition, and use common sense when assessing the test result.
- First check that the control module has a power supply and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the control module outputs. Remember that the test readings do not indicate whether the actuator is working.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
- The test readings given apply to a calibrated Fluke 88/97.
- The test readings %(+) and ms(+) show the signal pulse condition or length respectively. A test instrument with pulse rate or width measurement must be used. The sign indicates a positive trigger pulse, TRIG+.
