How to maintain the instruments and meters？

As we all know, instruments equipment are one of the important resources of laboratories, especially electronic measuring instruments. In daily work and research, in order to ensure the accuracy and reliability of the detected data, in addition to periodic verification, calibration, and periodic inspection of electronic measuring instruments and equipment, the daily maintenance of instruments, equipment and casings should also be done well.

 So why is it necessary to perform regular maintenance on our electronic measuring instruments?

1. Regular maintenance of the instrument can reduce the failure rate of the instrument. This should be well understood, because during the use of any instrument, with the change of the external environment, the aging of the equipment or the overloaded use of personnel, it is very easy to produce sundries, dust, moisture, air leakage, reduction or deterioration of the internal medium, etc. situation, resulting in abnormal operation of equipment, inaccurate display, frequent failures, etc. After all, cars now need regular maintenance, not to mention instruments?

2. Regular instrument maintenance can improve the accuracy of detection data. In addition to the verification, calibration, and period verification of the instruments and equipment, the maintenance of the instruments is also a method of process control of the equipment. Doing maintenance work well will improve the operating efficiency of the instrument and ensure the accuracy and reliability of the test data.

So do you know what are the methods of instrument maintenance? Although there are many kinds of analytical instruments in the laboratory, I think that the maintenance of various electronic measuring instruments is actually similar, and the maintenance of instruments and equipment can be done from the following aspects:

1. Develop equipment maintenance plan. For all instruments and equipment, determine various maintenance procedures and details according to their characteristics and usage.

3. Keep the inside and outside of the instrument clean, pay attention to moisture, rust and interference. Precision instruments should be handled with care. Optical parts should be wiped with lens tissue, not a damp cloth. I want to say here that the  the selected shell can protect the circuit board, so that the shell can be used for a long time. I also suggest that the enclosure should preferably be an aluminum boxes. YONGUCASE's aluminum enclosure has been arbitrarily customized to provide solutions, and the products are widely used in various industrial equipment. Of course, the electronic circuit board should be dusted, and the grounding of the instrument should be checked.

4. For the maintenance method of the instrument with high frequency, according to the characteristics of the instrument, it is a heat exchange, and the vents should be checked regularly, and the dust and burning debris should be cleaned in time; if it is a hydraulic machine or there is a medium solution in it, it should be Regularly check the discoloration of the medium or the interface decline, and replace the medium in time or add it in an appropriate amount; if it is a wearing part, it should be cleaned and replaced in time, such as the septum of a gas chromatograph; for instruments with water circulation, it is necessary to prevent the accumulation of dust and floating objects, resulting in Insufficient water flow will affect the cooling effect or affect the performance of the instrument due to the increase in electrical conductivity; for instruments using an air source, regularly check the gas connection with soapy water to prevent air leakage from causing accidents or affecting the accuracy of the results.

4. For electronic instruments and equipment with low frequency of use, it should be energized and preheated regularly to prevent deterioration of electrolytic capacitors, partial short circuit or poor performance of electronic circuit boards, which will affect the use effect of the instrument; Store it to prevent the battery from rotting and damaging the electrode; check the dry silica gel of the instrument frequently to prevent the internal parts from getting damp and affecting the stability index of the instrument.

After introducing the necessity and methods of maintenance of the above electronic measuring instruments, have you all mastered it? So are there any other issues that need attention? Of course there is! I hope it will be helpful and prompt for your future operations!

1. The operation should be carried out in strict accordance with the regulations, and the precautions should be strictly implemented. The instrument should be preheated in advance, and the heat dissipation or cleaning should be carried out according to the procedures. Otherwise, no matter how good the maintenance of the instrument is, it is meaningless.

2. The key parts of maintenance are the places that users often come into contact with. These contact points are prone to failure and should be maintained frequently.

3. Do a good job of equipment maintenance records, including maintenance time, a brief description of the maintenance situation, and replacement of parts. Through the record, you can understand the equipment maintenance status and dynamically grasp the cause of equipment failure.
