I. Daily Cleaning and Maintenance
1. Cleaning after each use: Wipe the friction head, sample stage, clamps, and other components with a clean, soft cotton cloth to avoid dye residue causing corrosion or contamination.
2. Avoiding corrosive solvents: Do not use strong solvents such as alcohol or acetone during cleaning to prevent surface oxidation or coating peeling.
3. Regular dust removal: Gently dust the inside of the instrument and ventilation openings to prevent dust from affecting the operation of the motor and sensors.
II. Protection of Critical Components
1. Counter: Avoid collisions or vibrations. Close the protective cover during use to prevent malfunction caused by foreign object impact.
2. Friction Head: Do not rub directly with sandpaper. Ensure the installation is level before testing. If replacing, ensure the new friction head has the same weight as the original component.
3. Transmission Mechanism: Apply grease or special lubricating oil to bearings, stainless steel grooves, and other parts at least once a month to ensure smooth operation.
III. Standard Operating Procedures
1. Power Management: Before powering on, check that the power supply voltage is stable. When shutting down, stop the machine first and then disconnect the power to avoid current surges.
2. Sample Installation: Ensure the sample is flat and wrinkle-free, and the clamps are secure to prevent slippage and abnormal wear.
3. Parameter Settings: Strictly adhere to the standard settings for pressure (9N), stroke (100mm), and speed (60 times/minute) to avoid overloading.
IV. Regular Calibration and Inspection
1. Calibrate at least once a year, or immediately after maintenance or upon discovering abnormal data, to ensure measurement accuracy.
2. Use standard samples for comparative testing to verify the reliability of the instrument's output data.
3. Establish calibration files and maintenance records to facilitate problem tracing and re-inspection arrangements.
V. Environmental Control
1. Place the instrument on a stable, vibration-free experimental platform, away from strong magnetic fields and high-temperature, high-humidity environments.
2. Maintain laboratory temperature and humidity within the standard range (20±2℃, RH 65%±4%) to reduce the impact of the environment on mechanical properties.
