Why Do Instruments Undergo "Aging" Before Leaving the Factory?

The aging process of instruments before leaving the factory (also known as "pre-aging" or "burn-in") is a process step where manufacturers conduct continuous power-on, loading, or operation of the instruments for a period of time by simulating actual usage environments and working conditions, so as to pre-trigger potential faults and stabilize performance parameters.

Simply put, it is like a rigorous "pre-job training" for new instruments. Only the "strong ones" that pass the test can finally leave the factory as qualified products, ensuring that the products delivered to users have stable and reliable performance.

1. Screening Early Failure Products: Through aging, potential quality issues caused by component quality, welding processes, etc., such as component damage, welding joint cracking, and material degradation, are exposed in advance, preventing unqualified products from entering the market.
2. Stabilizing Performance Parameters: Allowing electronic components (such as resistors, capacitors, and chips) and mechanical structures of the instruments to reach a relatively stable working state under simulated usage conditions, reducing parameter drift in the short term after leaving the factory.
3. Verifying Product Reliability: Conducting long-term operation tests on instruments in a controlled environment to verify whether they can meet the designed service life and performance requirements.

1. Product Connection and Placement: Place the product in the test environment to ensure it meets temperature and humidity requirements, and connect the power supply and test sensors.
2. Equipment Setting and Connection: Check the equipment status, connect data loggers, power supplies, and monitoring systems to ensure normal signal transmission.
3. Parameter Input and Adjustment: Set aging time, temperature, voltage, and other parameters, and calibrate thresholds according to product specifications.
4. Process Monitoring and Recording: Start the test, continuously monitor performance indicators, record abnormal data, and save experimental results regularly.
5. Test Completion: Cut off the power after reaching the preset time or conditions, disassemble the equipment, export data, and generate a test report.

Aging test is a necessary decision support tool that can provide reliable data basis for product quality. It can identify problems existing in product design and manufacturing and provide directions for improvement. It is an important link to ensure the quality and reliability of instruments, especially crucial in fields such as industrial control that have high requirements for instrument accuracy and stability.
