Packaging seal tester calibration procedure
After a long period of use, the leak tester will produce a display of inaccurate values. If you calibrate the pressure value, you are always confused. Today, Jinan Chenchi Instruments explains the method of calibrating the leak tester.
Take the MFY-01 sealability tester produced by Jinan Chenchi. First, prepare a standard negative pressure gauge and a hose tee. Then follow the daily operation method to connect the machine air supply line and the power cable. The next step is an important step. Disconnect the air hose connected between the main unit and the sealing barrel, and then insert the pre-prepared hose three-way connection according to the direction, and then connect the prepared standard negative pressure gauge. To the three links. When everything is ready, you can start the calibration. According to the daily operation method, the test is started. By observing the pressure difference between the main pressure gauge and the standard pressure gauge after the test, the deviation of the numerical value can be calculated simply.
