Proper calibration not only ensures the reliability of your equipment but also helps maintain compliance with industry standards. Whether you're working in a lab or on-site, following these procedures can significantly improve the performance and longevity of your tensile testing machine. Always refer to the manufacturer’s manual for specific instructions and make sure all safety protocols are followed during the calibration process.

How to Calibrate a Tensile Testing Machine
If you follow the adjustment procedure for the testing machine and other related instruments, it's important to perform regular calibration. To ensure accurate results, follow the steps below to check and adjust the calibration of the instrument.
1. Open the instrument panel and click on "Image Power." Then, set up the initial resistance adjustment box. Input 100Ω for the termination condition of the first circuit, while short-circuiting the rest of the input circuits.
2. Adjust the resistance setting for W12157.31Ω so that the output is 20mA. Then, adjust the potential for the 4mA output using W11. Repeat these steps until the accuracy falls within an acceptable range.
3. Use a standard square resistance to set the output to 20mA and 4mA, simulating the second loop. Adjust the next two settings—W22 for the second meter and W21 for the zero potentiometer. Ensure that the rest of the circuits are short-circuited during this process.
Calibrating the test machine in this way is typically a static process. However, it is sufficient for most transmitters' practical needs. Dynamic verification is uncommon, and most calibrations are performed using laser methods, which are usually reserved for special requirements.
Nevertheless, if you understand the parameters of the testing machine, calibration becomes more effective. Using these parameters ensures higher accuracy, leading to more reliable measurements.
