Edge crush strength is considered to be a vital aspect of the packaging industry. By testing the edge crush strength of different packaging materials like paper products, corrugated boxes etc. manufacturers can easily ensure the durability of materials when edge-wise compression force is applied to the materials. We at Testronix have designed a high-quality digital edge crush tester to test the edge-wise compression strength of the materials. This high-quality lab testing instrument has been designed as per industrial standards that make it easy for the manufacturers to conduct ECT on the materials.

If you want to ensure that your edge crush tester will remain at the top of the condition, it is important for the manufacturers to ensure that the machine is properly calibrated. In this blog, we will discuss brief information about edge crush testers and easy steps to calibrate this testing instrument.

Calibration procedure for Edge Crush Tester

Calibration of machines is an integral part of quality control in different sets of industries. By ensuring that the products will be calibrated accurately, manufacturers can easily any potential deviations or inaccuracies within machinery promptly so that corrective measures can be taken before they impact production processes negatively.

Testronix edge crush testing instrument is widely used in the paper and packaging industry and it is important for the product manufacturers to calibrate this testing machine at different intervals.

Below we have listed some easy-to-follow calibration procedures that you must use for performing calibration of your testing machine.

  • First, press RESET and TARE to set the load display to zero.

  • Set the Load Indicator and press RESET and MEMORY together again. This will show St-1 on the Deflection display and some value on the Load display.

  • Here press the PEAK key to shift the digits and enter the 80% value of the maximum load range of the machine in it. For example, if the machine has a maximum range of 100 kgf, the value that should be put in the load display should be 80 kgf.

  • After this press RESET and MEMORY together again.

  • This will show dot 1 on the deflection display and ----- on the load display. Now Press the RESET and MEMORY keys again to exit the load monitor setting menu.

  • After exiting the load monitor setting menu, check the values on the load indicator. If they match the values on the load monitor of the master calibration load cell then it means your machine is fully calibrated.

  • If the values don’t match, repeat the calibration procedure again.

In this way, you can easily calibrate the edge crush testing instrument.
