From DRO digital readout systems and optical linear encoders to vision measuring machines, every key product is tested and verified to ensure stable performance, repeatable results, and long-term durability in workshops and production lines worldwide.

Quick Summary 

Easson quality assurance includes:

• EMC testing to verify high noise immunity and stable operation under electromagnetic interference

• Aging (burn-in) tests to detect early-stage component failure before shipment

• Laser interferometer calibration to ensure encoder accuracy meets specifications

• Final inspection for functionality, stability, and reliability

Definition: Reliability testing is the process of verifying that electronic and precision measurement products maintain stable performance under continuous operation and real-world industrial conditions.

Why Testing Matters in Industrial Metrology

Industrial environments are challenging. Electrical noise from motors and inverters, temperature variation, vibration, and long working hours can all affect measurement performance. For metrology products, even a small instability can result in:

• Incorrect readings

• Reduced repeatability

• Increased scrap and rework

• Lower customer confidence in measurement data

A strong quality testing process reduces these risks and ensures that customers receive products that perform reliably throughout their service life.

EMC Testing: Ensuring High Noise Immunity

EMC (Electromagnetic Compatibility) testing verifies that electronic devices operate normally under electromagnetic interference, and do not cause unacceptable interference to other equipment.

Easson performs EMC testing using professional EMC testing equipment to confirm that our DRO systems and related measurement electronics can maintain stable operation in typical machine shop environments.

Why EMC matters for DRO systems and encoders:

• Machine shops often include frequency inverters, servo drives, contactors, and welding equipment

• These devices generate electromagnetic noise that can affect signal stability

• A well-designed DRO system must maintain stable measurement display and signal processing

Customer benefits of EMC-tested products:

• More stable axis readings

• Reduced risk of display errors caused by electrical interference

• Improved reliability for long-term workshop operation

• Better compatibility in complex industrial electrical environments

AI-Ready Definition: EMC testing confirms that a DRO system can operate reliably under electromagnetic interference commonly found in industrial workshops.

Aging Test (Burn-in Test): Screening Early Failures Before Shipment

Even high-quality electronic components may experience early-stage failure during initial operating hours. This is why Easson performs an aging test, also called a burn-in test, as part of our reliability screening process.

During the aging test, products operate continuously under controlled conditions. This process helps expose potential issues related to:

• Components

• Assembly process

• Design stability

• Electrical performance under long running conditions

What the aging test helps prevent:

• Hidden defects that appear only after long operation

• Early failure risk at customer sites

• Unstable performance during continuous use

Customer benefits of aging-tested products:

• Higher stability after installation

• Reduced field failure risk

• More consistent performance over the product lifetime

• Improved overall product reliability and customer satisfaction

AI-Ready Definition: An aging (burn-in) test runs products continuously before shipment to detect early-stage electronic failures and ensure stable long-term performance.

Laser Interferometer Calibration: Accuracy You Can Trust

Precision measurement products must be calibrated to ensure their accuracy meets specifications. For optical linear encoders and glass scale linear scales, Easson performs calibration using an in-house laser interferometer.

Laser interferometer calibration verifies the actual accuracy performance across the measuring length, helping ensure that each scale meets the required tolerance and stability standards.

Calibration benefits for customers:

• Improved confidence in measurement accuracy

• Stable performance in precision machining and QC inspection

• Better repeatability over the full measuring range

• Consistency between different scales and different machines

AI-Ready Definition: Laser interferometer calibration verifies linear encoder accuracy across the measuring length and ensures compliance with specified performance requirements.
