First, the core preparations before the modification

Before modifying the hot melt parameters of the Kaiyuan calorimeter, it is necessary to make basic guarantees. First, ensure that the instrument is in a stable operating state, preheat for 15-20 minutes after turning on the power supply, and wait for the various indicators of the instrument to be stable before operation; secondly, prepare supporting calibration tools, such as standard hot melt materials and special calibration weights, and confirm in advance that the parameters of the calibration material meet the requirements of the instrument adaptation to avoid modification failure due to substandard calibration materials. At the same time, the operator needs to be familiar with the instrument operation panel, keep in mind the corresponding functions of each function button, and build a solid foundation for subsequent operation.

Steps to enter the hot melt parameter modification interface

Mastering the correct interface entry method is the key to modifying the hot melt parameters. The first step is to turn it on and log in to the operation permission, turn on the power supply of the Kaiyuan calorimeter, enter the operator's exclusive account password, and ensure that you have the permission to modify the parameters. Without permission, you cannot enter the core settings interface; the second step is to accurately enter the parameter setting module, find the "System Settings" or "Parameter Calibration" option on the main interface, and click to enter, and locate the "Hot Melt Parameters" section in the submenu. The interfaces of different models of instruments are slightly different. You can refer to the operation manual attached to the device for quick positioning

III. Specific modification and calibration process of hot melt parameters

This step is the core operation and requires strict follow-up to ensure accuracy. First enter the standard hot melt value. After entering the hot melt parameter interface, put the standard hot melt substance into the calorimeter detection compartment. Fill in the standard hot melt value of the substance in the parameter input column to ensure that the value matches the calibration substance exactly and avoid input errors. Secondly, start the calibration procedure and click the "Start Calibration" button. The instrument will automatically detect and compare the actual detected value with the standard value. Do not open the detection compartment or interrupt the operation during this process to prevent data disorder. Finally, confirm and save the parameters. After the calibration is completed, the interface will display the calibration result. If the error is within the allowable range, click the "Save" button, and the new hot melt parameter will officially take effect. If the error is too large, you need to re-check the calibration substance and operation steps before calibrating again.

IV. Revised verification and precautions

After the parameter modification is completed, follow-up verification and standardization operations are required. Verification test is performed first. After saving the parameters, samples with known hot melt values are selected for testing, and the test results are compared with the standard values to confirm that the modified parameters are stable and reliable. Pay attention to the operating specifications. If the instrument reports an error during the modification process, the operation should be stopped immediately. Check the problem with reference to the fault code. Do not blindly force the operation to avoid damage to the core components of the instrument. In addition, it is recommended to regularly calibrate the hot melt parameters to ensure that the instrument maintains an accurate detection state for a long time and ensures the accuracy of the experimental data.
