Gel Time Recorder is a device used to measure the gel time of liquid materials (such as adhesives, resins, etc.). Gel time refers to the time when liquid materials begin to become colloidal (solid) and cannot flow, which is usually used for quality control and process optimization. In order to ensure the accuracy and reliability of gel time test, the equipment needs to carry out self inspection and self calibration regularly.
The following are the self inspection and self calibration procedures of the gel time recorder to ensure the stability of the instrument in daily use and meet the test requirements:
1、 Equipment self-test steps
Power check:
Ensure that the gel time recorder has been properly connected to the power supply and started normally.
Check if the power socket, power cord, and power switch are working properly.
Check if the display screen is functioning properly and if there are any alarm or error codes.
Sensor inspection:
Check if the temperature sensor (if any) is working properly. Test whether the gel time at different temperatures is consistent with the standard value.
Ensure good contact between the temperature sensor and the sample container to avoid affecting the test results due to sensor failure.
Confirm that the speed sensor (if any) is working properly to avoid testing errors caused by sensor issues.
Mechanical inspection:
Check whether the testing container and mixing device are operating normally, ensuring that there are no lags or mechanical failures.
Confirm that there are no foreign objects in the testing slot and clean any residue to avoid affecting the testing accuracy.
Display and alarm system:
Check if the display screen is clear and if the information is updated in a timely manner.
Check if the alarm system can issue alerts normally in the event of a malfunction.
Data record check:
Ensure that the device can record the gel time normally, and the data output interface (such as USB, serial port, etc.) can work normally.
Conduct testing and ensure that the data is accurate and error free, and store the data without any errors.
2、 Equipment self calibration steps
Temperature calibration:
Use a standard temperature source with known temperature (such as a temperature calibrator) to calibrate the temperature sensor of the equipment.
Place the standard temperature source at the testing location, set the instrument to a known temperature, and check if the instrument display matches the standard temperature.
If there is a deviation in the display, adjust the sensor reading according to the device's operating manual.
Mixing speed calibration:
Use a standard tachometer with known rotational speed to calibrate the stirring speed.
Set the mixing system of the gel time recorder to run, use the tachometer to measure the actual speed, and compare it with the speed displayed by the equipment.
If there is a deviation, adjust the speed according to the device's setting program.
Gel time calibration:
Test with materials with known standard gel time, and check whether the equipment can accurately record gel time.
Set the testing conditions (temperature, stirring speed, etc.), then start the test and record the results.
Compare the gel time measured by the equipment with the standard time to ensure that the difference is within the allowable range. If there is a significant deviation, adjust the equipment or contact technical support.
Data output calibration:
Compare test data with standard data to ensure that the equipment can accurately record and output results.
Check if the software version and output format of the device meet the standard requirements.
3、 Equipment maintenance and upkeep
Regular cleaning:
Regularly clean the testing tank, mixing device, and other components in contact with the sample to prevent sample residue from affecting equipment operation.
Use suitable cleaning agents to avoid corrosion and damage to sensitive components.
Check the battery and power system:
If the device uses batteries, regularly check the battery level to avoid testing interruptions caused by insufficient battery power.
Keep the power socket and connecting wires clean and stable to avoid affecting testing accuracy due to power issues.
Regular inspection and calibration:
Perform calibration at regular intervals, especially when frequently used or when equipment malfunctions, conduct a comprehensive inspection and calibration.
Record and report:
After each device self check and self calibration, record the results of the inspection and calibration and report to relevant personnel. Calibration reports can be generated as part of the equipment maintenance file.
4、 Common troubleshooting
No display on the screen:
Check if the power connection is normal.
Confirm if the display screen is damaged or has poor contact.
Unable to calibrate:
Confirm if the sensor is connected properly.
Check for software issues and whether firmware updates are needed.
Inaccurate measurement of gel time:
Check if the sample meets the testing conditions (such as temperature, stirring rate, etc.).
Confirm whether the sensors and testing components of the equipment are working properly and whether recalibration is necessary.
Data recording error:
Check if the data output interface is functioning properly to ensure that the data can be transmitted correctly.
Ensure that the storage space of the device is sufficient to avoid data loss.
5、 Conclusion
The self inspection and self calibration procedures of the gel time recorder are the key steps to ensure the accuracy and reliability of the equipment. By regularly checking the power supply, sensor, mechanical part and data output system of the equipment, and calibrating the temperature, speed and gel time, the service life of the equipment and the accuracy of the test results can be effectively improved. Meanwhile, maintenance and common troubleshooting are also necessary measures to ensure the normal operation of the equipment.
