EMC Testing equipment
To Make sure all Easson Digital Readout products can be pass the standard EMC specification, we have a complete set of EMC test esd immunity tester for EMC testing.
Easson DRO have been to conforms to relevant standards for the electromagnetic compatibility ( EMC ) as the details below:
IEC61000-4-2 / GB / T 17799-2: Electrostatic discharge immunity ( Contact discharge 6000V, air discharge 8000V )
IEC61000-4-4 / GB / T 17799-4: Electrical fast transient burst immunity ( pulse amplitude 2000V )
IEC61000-4-5 / GB / T 17799-5: Lightning surge immunity ( Superrimposed pulse voltage peak 2000V )
Easson Digital readout power supply use a linear power transformer and power filter, this can help our products pass by the noice immunity and the EMC.
To reduce the total heat generation inside the ES DRO in order to obtain long working life. An ultra low temperature rise transformer that construct with very high permeability icron core is used, which effectively bring temperature rise to only about 5℃.

FAQs
1. Who we are?
Easson is a manufacturer in design and manufacturing precision measuring equipment. Vision Measurement Systems, Optical Profile Projector, Digital Readout System(DRO), Linear encoder glass scale.
2. How can we guarantee quality?
We are implementing the Total Quality Management (TQM) system to our factory in China for more than 20 years. Strict control of production processes and quality records and labour trainning, also products aging test etc.. All this to ensure the quality assurance always be implemented throughout all the production processes.
3: Did you accept OEM customized service?
Of course, we can provide not only typical products but also the products customized to customer's request based on the order quantity.
4: What is your company mainly produce?
A: Mainly produce Vision Measurement Machine, Optical Profile Projector, Digital Readout System(Counter), Linear encoder glass scale. CNC linear scale.
5: How can I identify Easson Incremental and Absolute linear encoder?
First, we has the product code label stick on the scale body, moreover, absolute scale additional has the ABS Zero label show it is the Absolute linear scale; Second, Absolute scale has a small PCB inside the connector which can store the non-linear compensation data for high accuracy measurement.
6: How long dimension for the linear encoder scale you can produce?
A: Up to now, the maximum 3000mm long glass scale.
