The correct use and maintenance of university laboratory testing instruments

University laboratory testing instruments in the use of the process to ensure the accuracy and reliability of the measurement results, the use of instruments and maintenance personnel, we must do the correct, reasonable operation and use of testing instruments, and do a good job of routine maintenance of testing instruments. Specific can be carried out as follows.

1, test instrument operators in the operation and use of the instrument before the necessary technical training, familiar with the instrument's manual, understand the instrument's performance, the role of accessories and usage, familiar with the operating methods, strictly in accordance with the operating procedures, for some professional and complex operation of the instrument, can be arranged to be responsible for the operation, and require the operation before obtaining an induction certificate.

2、The environment in which the testing instrument is used should meet the requirements of the operating instructions.

3, the operator must know whether the existing technical state of the instrument is normal before using it, whether the calibration certificate is within the validity period, whether the working voltage, circuit, gas circuit, oil circuit, mechanical rotating parts meet the requirements before powering on and using.

4, for valuable, precision and other large instruments and equipment, should be developed operating procedures, the use of personnel should be strictly in accordance with the operating procedures, and fill in the "record of the use of instruments and equipment".

5、If the instrument and equipment fails or is damaged during use, it should be stopped immediately and reported to professional maintenance personnel for overhaul, and it is forbidden for non-professional maintenance personnel to carry out maintenance operations on the machine.

6、Regular maintenance of the instrument and equipment, such as the working surface of the working rails and gears and rack on the instrument for regular lubrication, regular anti-rust treatment of the instrument, the machine should be not used for a long period of time between the machine for power, to prevent damage to the electrical parts of the moisture.

7、In addition to the professional maintenance personnel of the instrument, no one else should disassemble or adjust the instrument arbitrarily to avoid damaging the performance of the instrument.

8、At the end of use, carry out necessary maintenance on parts that may affect the performance of the instrument, such as hand contact with non-painted parts, such as surface cleaning, spraying anti-rust oil, etc., and then cut off the working power.
