There are many kinds of testing machines, such as electronic universal testing machine, hydraulic universal testing machine, friction and wear testing machine, etc. it can be said that these testing machines belong to a universal testing machine, but there is a big difference, that is, the application performance of each testing machine is different, so we must pay more attention to it.

1. The measurement range can be expanded by selecting additional force sensor;

2. The adjustment range of force control rate can also be selected according to the stress rate, the stress rate = force control rate / original cross-sectional area of the sample;

3. The adjustment range of deformation rate can also be selected according to the strain rate, the strain rate = deformation rate / original gauge distance of the sample;

4. Both the force control rate and the deformation rate are related to the material of the specimen, and their ranges cannot exceed the range of the displacement rate;

5. In order to avoid the permanent deformation of the force sensor, the test force should not exceed 50% of the full scale of the sensor during the long-time holding test;

I hope that the introduction above can help you to operate accurately, so as to effectively ensure the safe application of the equipment in the later period.
