How do you verify the performance of a device after maintenance?

• A. Guess by feel.
• B. Look at the device and assume it's fine.
• C. Have the client sign off without testing.
• D. Run a test with the device and check returns against baseline or manufacturer specifications.

Answer: (D)

After maintenance, verification is about objective proof that the device still performs within expected limits. The best approach is to run a test with the device and compare the results to a baseline or to the manufacturer’s specifications. This means operating the device under normal conditions, measuring the relevant performance parameters, and confirming that outputs, consistency, and safety features meet the stated tolerances. Document the results, and if any parameter is outside spec, adjust and re-test until it passes. Relying on feel, appearances, or client sign-off without testing does not provide reliable evidence of proper function and could miss hidden issues, so those paths aren’t acceptable. This practice helps ensure client safety and device reliability after maintenance.
