1、 Daily operation standards

1. Strictly follow the operating proceduresBefore use, carefully read the instruction manual to understand the performance, operation methods, and precautions of the instrument, in order to avoid equipment damage or measurement errors caused by misoperation.

2. Handle with care to avoid vibrationThe internal components of the instrument are precise, and strong vibrations should be prevented during movement. Reliable protective measures should be taken during high-altitude operations to prevent the instrument from falling or colliding.

3. Standardize the operation of knobs and plugs：

   • Do not apply excessive force when rotating or pressing the knob, especially when the knob is in theharshAttention should be paid to the position to prevent the knob from being misaligned or damaged.
   • When unplugging the power plug or probe plug, the plug housing should be grasped by hand to avoid pulling and plugging the cable and prevent cable damage.

4. Clean and reset promptly after use：

   • After use, the surface dust and oil stains of the instrument should be wiped off in a timely manner to keep the instrument clean.
   • Restore the equipment to its original state, count the equipment accessories, organize and fill in the usage records for subsequent tracking and management.

2、 Environmental management

1. Control the usage environment：

   • Avoid using the instrument in environments with strong magnetic fields, high dust, large power fluctuations, strong vibrations, and high or low temperatures, as these environmental factors may interfere with the normal operation of the instrument and even damage it.
   • When the instrument is working, rain, snow, water, engine oil, etc. should be prevented from entering the interior of the instrument to avoid damaging the circuits and components.

2. Adjust temperature and humidity：

   • In humid areas or seasons, when the instrument is not used for a long time, it should be powered on regularly for about half an hour to remove moisture and prevent internal short circuits or breakdowns of the instrument.
   • For instruments with strict requirements for cleanliness and temperature and humidity, the condition of the equipment usage and storage environment should be regularly checked to achieve dust prevention, temperature regulation, dehumidification, corrosion prevention, insect prevention, shock resistance, etc.

3、 Regular maintenance

1. Develop maintenance planBased on the characteristics and usage of the instrument, determine various maintenance processes and details, such as daily maintenance, primary maintenance, secondary maintenance, etc.

2. Perform maintenance operations：

   • routine maintenancePerform routine maintenance according to the operating and management procedures of the instrument, including external cleaning, appearance inspection, equipment debugging, etc.
   • first-level maintenanceFrom the outside of the device to the inside, perform global cleaning, lubrication, and fastening. Perform partial inspection and adjustment on instruments that can be disassembled for general maintenance (such as dismantling the casing), and conduct power on test runs or moisture removal on the entire instrument.
   • secondary maintenanceMaintain the interior of the instrument, including disassembling or adjusting the main components of general detachable instruments, and replacing vulnerable parts. Recheck and assemble all supporting components in the complete set of instruments, and replace any vulnerable parts. Perform precision checks, calibrations, and calibrations on various instruments that have been in use for more than three years.

3. Check and replace vulnerable partsRegularly inspect the external condition of the sensors in the testing equipment. If there are any damages, looseness, displacement, dust accumulation, or moisture, they should be dealt with in a timely manner. Regularly replace parts that show signs of wear to avoid equipment damage or increased measurement errors caused by excessive wear of parts.

4、 Fault handling

1. Timely troubleshootingIf any problems are found with the instrument during use, the power should be immediately turned off and maintenance personnel should be promptly asked to check and repair it. Do not operate with illness to prevent the fault from expanding or damaging other components.

2. Standardize the repair process：

   • Request the relevant company leaders to assist in understanding the instrument malfunction, and determine the extent of the malfunction after review.
   • The testing personnel shall fill out the instrument repairman card according to the relevant regulations of the company or laboratory.
   • Repair the instrument, report to the laboratory manager after the repair work is completed, and the instrument can only be put into use after being accepted and signed by relevant personnel.
