What are the precautions and methods for zeroing up the hydraulic universal testing machine?

The hydraulic universal testing machine is designed and manufactured in accordance with the standards of GB/T3159-2008, GB/T228-2002 and GB/T 7314-2005. It is mainly used for tensile, compression, bending, shearing tests of metal and non-metallic materials. How much do you know about hydraulic universal testing machines? What are the precautions and methods for zeroing up the hydraulic universal testing machines? The following editor will give you a detailed introduction to these two issues, let’s take a look.

1. Precautions for zeroing of hydraulic universal testing machine

1. When the zero point is too large, adjust the zero point first, and then clear the software in each gear.

2. When the oil cylinder has not risen, the test force shows a negative value, which is a normal phenomenon. Please do not adjust the zero point.

3. For the adjustment of zero point, it should be performed after the extensometer is clamped on the sample and the test piston is in a stationary state.

4. Under normal circumstances, the speed control personnel have adjusted the zero point of the sensor. Each time the start, the system will automatically calibrate the starting zero point without user adjustment.

5. Users can use the hardware zero button to adjust the hardware zero point, and the system will automatically record the new zero point adjustment value.

6. No gear measurements are not adjusted. Therefore, for hydraulic universal testing machines, because they are not divided throughout the process, this matter applies to electronic universal testing machines.

2. Method for zeroing adjustment of hydraulic universal test machine

1. Turn on the test equipment, computer, and control software

2. For the hydraulic universal testing machine, select the appropriate range according to the sample, adjust the oil supply valve to raise the cylinder piston, and repeat it several times. When the piston is rising and does not bear pressure, observe whether the test force value of the computer at this time is zero. If it is not zero, click the hardware adjustment button to adjust the zero point.

To sum up, the precautions and methods for zeroing up the hydraulic universal test machine. When using the press test machine, the operator must use it in accordance with the procedures and specifications of the instructions. Otherwise, it is easy to cause dangerous situations such as machine failure and personnel injury. If you have any unclear areas, please call us for consultation. So that we can choose the product that suits you according to your actual situation.
