An auditor can ask about monitoring resources in ISO 9001 by focusing on how the organization determines and provides the necessary resources to ensure valid and reliable results to verify the conformity of products and services. They may ask questions such as:

- How does your organization determine the resources needed for monitoring and measuring activities?
- How do you plan the preventive maintenance of monitoring and measuring resources?
- Can you show me the maintenance records of the monitoring and measuring resources?
- Which standards are followed for the calibration or verification of measuring equipment?
- How do you safeguard your measuring equipment?
- What do you handle measuring equipment that is not in use?
