CIRAS-2 photosynthetic apparatus uses frequently asked questions and answers What is going on and then solved? A: It may be because the ambient humidity is too high or the ambient temperature is too high. Shade the instrument under strong light when in use. 1Q: How to change the absorption tube behind the photosynthetic apparatus when measuring the CO2 response curve A: Replace one of the absorber tubes (5 pieces) on the back panel of the photosynthetic apparatus with soda lime and check if other absorber tubes are deteriorated. If the CO2-photosynthetic response curve is not measured and the photosynthetic rate is measured using atmospheric gas supply, the intermediate tube is replaced with an empty tube. Note: The soda lime tube is normally blue-green, and it is khaki after deterioration. The desiccant (silica gel) is normally yellow and green after deterioration. 2. Q: When the buffer bottle is connected, where is the air inlet connected? A: Connect to the far right of the back panel of the instrument, from the top to the bottom of the second hole. It is an air intake hole. 3Q: Close the leaf room light source is not bright, how to solve? A: A see if the interface of the light source is not connected. B. See if the leaf chamber is not close. When you are not close together, think that the leaf chamber is not closed. If normal running appears below the screen, it indicates that the leaf chamber is normally closed. C See if the light source setting of the instrument is LED, that is, Light type: LED If you still can't solve it, please contact us at 0538-8241341 4Q: How to make a buffer bottle? A: Find a bottle of 2L and above, wear a cover, clean it, dry it, make a hole in the cap, and insert a buffer tube of 3m or more into the buffer bottle. See the instructions for the buffer bottle. 5Q: After booting, the screen does not light, the red light on the back of the instrument is on, the green light is flashing, what is the reason? A: Press the ZZZ button on the instrument screen, the notebook may be turned off during shutdown. After pressing the “Zz†button, if the screen still does not light, please contact us at 0538-8241341. 6Q: It shows normal operation after starting up, but what is the value of Cr (the external atmospheric CO2 concentration) is less than 300? A: This is because the zero adjustment is not completely caused. It is enough to replace the molecular sieve in the absorption tube and replace the analysis sieve near the black panel with a new one. 7Q: The instrument is running normally, how is the Pn value going up and down, if it is handled? Answer: First check whether the Cr value at the upper left of the instrument operation interface is stable. If it is unstable, please check whether the air source and buffer bottle are in a reasonable position. If Cr is stable, check that the leaf chamber does not fully tighten the blade. If not, adjust the screw behind the handle of the leaf chamber to tighten the chamber. If you can't eliminate it, please check if the air tube in the head of the leaf chamber is off. If you have any questions, please contact 0538-8241341. 8 Q: How to judge whether the leaf chamber is leaking? Answer: The instrument normally closes the leaf chamber and turns on the light source. When viewed from the side, if there is light from the leaf chamber where the blade is exposed, it indicates that the leaf chamber is not tight. At the time of normal measurement, when photosynthetic stability is achieved, air is blown around the leaf chamber, and if the photosynthetic value fluctuates in the climatic climate, it indicates that the leaf chamber leaks. If the chamber leaks, adjust the screws behind the handle of the chamber or replace the sealing material on the chamber. 9Q: What should I pay attention to when doing light intensity-photosynthetic response curve? A: Before the experiment, the plants should undergo sufficient light adaptation. B When measuring the light intensity response curve from high light intensity to low light C light intensity response curve is to change only the light intensity, other environmental settings can not be changed Question 10: What problems should I pay attention to when measuring daily changes? Answer: A test plant should be completely unshaded, and the sample to be measured should be selected before the experiment, and the corresponding mark should be marked accordingly. When the B measurement, the angle of the leaf chamber must be consistent, and the inconsistent angle of the leaf chamber will cause the light intensity to change greatly, and the measurement has no meaning. The measurement time of the C measurement day should be turned on before the start of the test, which is helpful for the smooth progress of the experiment. The time of the measurement is about 6 or so. 11Q: During the experiment, the sudden sound inside the instrument increased? What happened after disappearing? A: The internal sound of the instrument suddenly becomes larger. The internal pump work of the instrument is increased. The gas gambling game is caused by the gas pipe gambling. It is most likely caused by the air intake pipe. 12 Q: In the process of using, suddenly black screen, how is it solved? A: The biggest possibility is that the battery has no points or the battery is in poor contact. If it is determined that the battery has power, the battery is not in good contact, please repair the engineer. 13Q: What is the red and black line at the back of the leaf room? A: It is used for external large batteries. The instrument comes standard with a similar red and black line. The battery can be used to supply power to the chamber. Especially when the temperature is controlled, the power supply to the chamber can greatly increase the battery life of the host. . 14Q: What should I pay attention to when changing the leaf chamber window? Answer: When replacing A, be careful not to screw the wire. Apply some sealant to the edge of the new leaf chamber window when replacing B. If you are not sure, please call the engineer.
