Instrument Usage
It is used to automatically measure the breaking strength, breaking elongation, breaking strength, breaking time and tensile curve of single yarn and chemical filament. Equipped with a Lenovo brand computer, it makes the data collection, calculation and output all automatic.

● Abnormal data automatic rejection function, timed stretch function, data saving and query function.
● Fully automatic analysis, and automatic statistics, analysis, printer to print data and graphs.
● No need to hang pre-tension weights, there is a computer to automatically control the pre-tension.
● Rapid automatic force correction knob, only need to lightly press once can be fully automatic force zero correction.
● Internal circuit design adopts independent function system circuit boards, which reduces the time for repair and maintenance.
● The percentage (%) of breaking stretch can be set according to the needs of different yarns.
● The upper and lower limits of strength and elongation can be set, and the test will be stopped automatically if the limit is exceeded, or the test will be executed according to the set instructions.
● Reference strength and elongation points can be set, and the data will be printed out automatically.
The data after testing can be automatically stored in the hard disk drive for convenient management and application.
The software program adopts a window screen and can be operated with a mouse, which is easy to learn and use.
No special interface is required and it is compatible with general domestic computers, so the use and maintenance costs are low.
Adopts Delta's high-speed motor drive mechanism to enhance testing efficiency.
