Tension testerIt has a wide range of application. Its allowable errors in the force measurement system, extensometer level, and all allowable errors in the extensometer, and all-round test machine instrument standards will be taken to you by Jinan Hengsi Shanda Instrument Co., Ltd. to learn more details.

Table 1: Allowable error of force measurement system

Precision level	Allowed value %
Relative error of display value q	Relative error of display value repeatability b	Relative error of the value return journey v	Relative error of zero point F0	Relative resolution a
