SPAD502 chlorophyll meter is the most widely used professional instrument for determining the green content of plant leaves in plant physiology research. The instrument is small in size and superior in performance. It plays an important role in the actual measurement test and effectively ensures the measurement result. The authenticity and accuracy of the test increase the efficiency and precision of the test. As SPAD502 chlorophyll meter is more and more widely used in modern agricultural scientific research, in order to allow more people to use the instrument better, the agricultural instrument network Xiaobian will do the common problems and solutions for the SPAD502 chlorophyll meter. A brief introduction. Question 1: open the switch, the display shows no check and solution: This type of problem is mostly due to the battery is not normal to the instrument caused by power, so first check the battery is installed correctly or whether the battery is charged, you can take reinstall the battery or replace Battery solves the problem. Question 2: After the measuring head is closed, it cannot be measured. Inspection and solution: When this problem is encountered, first of all, it is necessary to consider whether the instrument has been calibrated without the sample. If it is not found, the calibration must be carried out first before the problem can be solved. Question 3: Poor measurement repeatability. Check and Resolution: During the measurement process, there are many reasons why the repeatability of the chlorophyll meter measurement of the SPAD502 is poor. Therefore, to solve such problems, you must resolve the problem in different situations. 1. Check whether there is water in the transmission window or receiving window. The solution is to use a dry, soft cloth to wipe the emission window and receiving window; 2. Check whether the sample has more veins. The solution is to test several such samples. , find the average; 3, to check whether the direct measurement in the sun, the solution is to shading SPAD502, to avoid the impact of sunlight on the measurement; 4, check the position of the sample is correct, the solution is to adjust the sample under the midline to ensure that the sample Completely cover the receiving window; 5. Check whether the measuring head is closed and completely closed until the end of the measurement. The solution is to close the measuring head and hear a click. The measured value is displayed on the screen. Question 4: Loss of measured value from memory Check and Resolution: The SPAD502 chlorophyll meter can be installed with a memory card to store measurement data, so if the measured value is found to be missing from memory, it can be checked whether the switch was turned off because shutdown will clear RAM. If the switch is turned off, turn on the switch and data can be stored normally. KINMAN, a leading manufacturer in China, specializing in a galaxy of Trailers & Trailer Parts .
