How to adjust the zero point by hydraulic universal testing machine

The hydraulic universal testing machine uses a computer to control and display the test. While using it, the equipment must be zeroed. Today, the editor will briefly introduce it.Hydraulic universal testing machineRelated operations and some precautions:
.Open the test equipment, computer, and control software.
Second. 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.
Notes:
.When the zero point is too large, first adjust the zero point, and then clear the software in each gear.
Second. 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.
Third. Adjustment of the zero point should be performed after the extensometer is clamped on the sample and the test piston is in a stationary state.
Fourth. Generally speaking, the speed regulator has adjusted the zero point of the sensor. Each time it is started, the system will automatically calibrate the starting zero point without user adjustment.
Fifth. 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.
Sixth. No grading measurements do not adjust zero points, so forHydraulic universal testing machineFor example, because the whole process is not divided, this matter applies to electronic universal.
