Name: Automatic Drop Tester Model: RS-DP-03A Application: The machine is aimed at assessing the effect of unintentional drop of the product by user in actual use on the product performance, which is applicable to the original-gesture drop test of mobile phone, tablet, e-reader, telephone, e-dictionary and other consuming electronic products. Specification: Model Max drop height Drop height setting Touch panel setting and display Tester size Weight Power supply Advantages: Structures and Functions: 1. This machine adopts AC variable-frequency and variable-speed motor plus synchronous pulley for adjusting drop height range, which is durable. 2. This machine adopts a color LCD touch panel plus PLC for motion control and set, by which drop cycles can be reset and power-off memory function is provided; all control parameters will be set via the touch panel: drop, reset, height resetting, number of drops and account etc.; 3. Operator just needs to input the size of the product to be subject to drop test via the screen only: Length L, Width W, Thickness T, Diagonal Interval DI; so that the test can auto raise up to the set drop height for testing; 4. After the drop finishes, the fixture block will automatically return to the set sucking height (generally, at a height of 600~800mm). 5. 4 corners, 8 edges, 2 faces, 2 sides can be set to drop and impact on base, if the product is not regular shape, we can make the clamping fixture for the test. 6. The product will be released at the height around 300mm, that can make sure the impact gesture of the product on the base. 7. The drop bases: steel plate, marble board, wood board. Accessories: The fixture for fixing tested sample: Software: The testing interface:

The speed and stability calibration: The drop speed and the stability of this tester have been verified by the high speed camera. The high speed verification picture and the graph.
