Explore stator, rotor and winding condition questions, then connect the test plan with the records and equipment required by the asset.
Choose a route through the test question.
Explore stator, rotor and winding condition questions, then connect the test plan with the records and equipment required by the asset. Start with the asset documentation and the reason for the work so the reading stays connected to the required decision.
1. Define the question
Identify the asset, the project stage and the evidence the test needs to provide.
2. Read the method
Use the detailed guides to organise the setup, comparison and reporting questions.
3. Match the equipment
Compare the current configurations against the required scope and working environment.
Stator and winding assessment
Start with the winding condition question and the asset documentation. Use the method guides to organise the test record and compare the available supporting evidence.

Rotor and operating condition
Connect the test arrangement with the part of the machine being investigated. Keep the configuration, operating history and relevant reference information with the measurement.

Test programs and instrument selection
Plan the test window and reporting requirements alongside the diagnostic scope. Compare equipment against that program and confirm the configuration for the actual machine.

Connect the method with equipment.
Use the measurement task, asset configuration and reporting requirements to compare instruments. Confirm the exact specification and accessories on the current product page before choosing a configuration.
Keep the record connected to the result.
Identify the asset and the purpose of the test. Retain the instrument, connection details, relevant conditions and reference documents with the result so a later comparison can use the same context.
When a result raises a condition question, review the setup and the other available evidence with the applicable asset and project requirements. Define the follow-up scope before expanding the equipment list.
Build the test setup around the application.
Share the asset type, test objective and working environment so the equipment configuration can be reviewed against the actual task.
Use this overview to organise the reading. The applicable approved procedure and asset documentation define test work, equipment settings and acceptance criteria.
