WDW-20 Microcomputer Controlled Electronic Universal Testing Machine for Tension Test
Description:
- Support for multi-language user-interface extendibility, pre-installed with American English and Simplified Chinese.
- Dynamic display of load, displacement, deformation and real-time testing curve on the screen.
- Support for displaying a single curve of a specimen or the overlay of multiple curves.
- Closed loop control of channels such as load, displacement, deformation, etc. Smooth switching in between.
Features:
- Capability of mechanics testing on various metal materials. e.g. Metal tension, compression, bend, shear, etc.
- Capability of mechanics testing on various nonmetal materials. e.g. Wire tension, plastic bending, cable peeling, etc.
- Domestically pioneered open-testing-method settings. Engineers may set up testing projects then operators may employ the projects for testing, greatly reduced the difficulty of the operations and the requirement in the skills and trainings of the operator.
- Domestically pioneered process-oriented design of testing control. Provides users with intuitive testing control procedures and a wide range of instruction types. Also supports dynamic instruction parameter assignment.
- Domestically pioneered highly efficient three-level operation model of testing data processing. Supports open testing data processing, appending custom testing data items and re-inspection of processed testing data.
- Support for multi-language user-interface extendibility, pre-installed with American English and Simplified Chinese.
- Dynamic display of load, displacement, deformation and real-time testing curve on the screen.
- Support for displaying a single curve of a specimen or the overlay of multiple curves.
- Closed loop control of channels such as load, displacement, deformation, etc. Smooth switching in between.
- Rounding off of numerical testing data complies with GB 8170-87 (UDC511.1/2) Rules of Rounding Off for Numerical Values, supports rounding off in sections and custom rounding off.
- Characteristic testing data can be marked on testing graphs.
- Capable of statistical operations on testing data (average, standard deviation, coefficient of variance).
- Automatic requesting for testing result data, also capable of launching an advanced analysis to inspect the data.
- As many as 20 layers of sensor linear compensation, elevates the precision of the instruments to the next level.
- Support saving, instant retrieving and inspection of testing results.
- Capable of re-analyzing test data and curves, and partial zooming of testing curves at will.
- Open testing report, support custom testing template, automatic generation of testing report, which can be printed, previewed or saved as files.
- Integrated with software limit protection, hardware travel limit protection and full scale overload protection.
