In the past, because the farmers were unclear about the causes of crop diseases and the diseases they belonged to, the drugs were often unscientific. This not only caused waste of resources and economic losses, but also failed to achieve good control and prevention, and agricultural production was not effective. Protection, and with the development of science and technology, the use of crop disease detection equipment for diagnosis, and then scientific prevention and control, has become an effective means of crop disease prevention and control, and has achieved good results, so the use of crop disease detection equipment It is also constantly expanding, but as an instrument product, it is still difficult to avoid some common faults in the process of use. What should the user do when he encounters a fault of a crop disease diagnosis instrument?
The fault diagnosis of crop disease diagnosis and diagnosis instrument can be mainly divided into three kinds of situations. One is the instrument startup, the second is the printer part, and the third is the detection result. The following describes the fault phenomenon and the corresponding exclusion method.
1. There is no display on the screen of the crop disease diagnosis and diagnosis instrument Most of the reasons for this are that the instrument is not powered on, so it is necessary to check the power switch part, such as checking whether the power switch is turned on, whether the fuse is broken, etc., find the cause, and solve it.
2. The printer does not print or there is printing paper but no paper shows that the crop disease diagnosis instrument is equipped with a printing function, that is to say the result of the detection can be printed out by the printer, but the user sends a response, which is encountered in the printing section. The printer does not print or has paper, but no paper is displayed. This may be caused by the fact that the printer is not turned on or the printer is out of paper. Therefore, the printer should be placed in the “on†position before printing and the printer must be guaranteed. Already installed paper.
3. Inaccurate test result The test result is inaccurate This is a concern for the user, because it is related to whether the test can be carried out smoothly. Generally, the cause of the inaccurate test result of the crop disease tester is related to the test strip. For example, if the test strip is deteriorating, the test strip is displaced during the test, the test strip is not placed properly, the test strip is contaminated by residual juice on the stage, or excess juice is left on the test strip. In different situations, when changing the test strips, retesting, or during the operation, ensure that the test strips are placed close to the top of the test strips; clean the test platform and dry the excess juice with absorbent paper before re-determination.
