The digital dynamometer uses a large display screen to accurately measure the maximum amount of information obtained in reality; The current value, maximum value, minimum value, etc. can also be used to indicate whether the test force is approaching the maximum range in the form of a progress bar. If necessary, the backlight can be used to make the reading more convenient and comfortable.

The standard force measuring instruments used for the verification or comparison of static weight, lever, hydraulic, and superimposed force measuring machines are mostly of the force measuring sensor type, and their accuracy is divided into three levels: 0.01, 0.03, and 0.05. After various forms of force measuring sensors are equipped with appropriate electrical measuring instruments, they constitute a sensor type force measuring instrument or an electronic force measuring instrument. Standard force-measuring instruments still rely mainly on resistance strain type sensors with wide range, high accuracy, and strong adaptability. Standard force-measuring instruments used for the verification or calibration of various material testing machines are mostly dial gauge type, with accuracy levels of 0.03, 0.05, and 0.1.
