EMC Testing equipment
To Make sure all Easson DRO products can be pass the standard EMC standard specification, we have a complete set of EMC test esd immunity tester.
Products Description
EA-927 is an all in one and full options DRO which have specific functions which are very important to machine retrofitting, such as Non linear compensation, Axis speed display... and many others important features that make it the ideal solution for retrofitting to many different type of machine tools( Such as Milling, Boring Machine, Lathe, Grinding etc).
To make the DRO much more user friendly, the display message can be confirured to one of the following languages:
1. ENGLISH 2. CHINESE 3. GERMAN 4. SPANISH 5. ITALIAN 6. PORTUGUE 7. ARABIC 8. CZECH 9. FRENCH 10. HINDI 11. INDONESI 12. JAPANESE 13. KOREAN 14. PERSIAN 15. ROMANIA 16. RUSSIAN 17. SWEDEN 18. THAI 19. TURKISH 20. VIETNAM

| Power Failure Position Function ( Only work with Easson Absolute linear Scale) |
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℃.
Aging Test
Easson Digital Readout Systems need to do the aging test, using three axis signal generator counting, make sure all couting reading correctly, high temperature test and load test for 3 x 24 hours before QC procedure.
