Planning and equipment selection
Keep the evidence connected to the review.
Identify the asset and the specific question being assessed. Retain the instrument, configuration, relevant conditions and reference documents with the result so the next review can follow the same context.
Record the asset, measurement configuration and relevant conditions. Read the method guides alongside the available reference evidence before selecting the instrument and reporting workflow.
The approved test procedure and asset-specific criteria define the work and its acceptance review. Use this collection to organise the questions and compare equipment, then confirm the complete configuration for the application.
Connect the workflow with equipment.
Compare the published functions, configuration and reporting workflow against the identified task. Confirm the current specification and accessories for the asset before selecting a model.
Review the setup for your application.
Share the asset type, the test objective and the working environment so the configuration can be reviewed against the actual task.
