Some matters that should be noted when operating the programmable constant temperature and humidity box:
1. The constant temperature and humidity box is equipped with a test hole on the machine side, which can be connected to the test circuit in the box. 2. If you want to observe the change in the box during the test, you can turn on the light of the indoor lamp (LIGHT) and you can see the inside through the window. Change situation.
3. If the machine is running at 0°C or lower, try to avoid opening the box, because when you are doing low temperature, if you open the box, it may cause the ice-sealing phenomenon inside the evaporator and other parts, especially the lower the temperature is, the more serious the situation is. , If it must be opened, the door opening time should be shortened as much as possible. 4. When the low temperature operation is completed, it is necessary to set the temperature condition at 60°C for drying for about half an hour to avoid affecting the measurement time or ice formation of the next working condition.
5. The radiator (condenser) of the freezer should be regularly maintained and kept clean. 6. When the humidifying barrel enters the water pipe, the remaining air must be completely discharged to prevent it from entering.
pay attention:
When the constant temperature and humidity box is completed with low temperature operation, if it is not working at the 6th point above, it is also necessary to set the normal temperature condition (30±5°C) so that the temperature inside the box is at room temperature when it is stopped, so as not to affect the temperature inside the box. Low icing phenomenon and fogging of the window glass.
7. During operation, do not open the door unless absolutely necessary. Otherwise, the following adverse effects may result:
-- High temperature moisture rushes out of the box ..... very dangerous -- the inside of the door is still kept at a high temperature ..... damage -- high temperature air may trigger a fire alarm and cause malfunction 8. Please note that this machine must be safely and reliably grounded , in order to avoid static induction 9. Avoid switching the refrigerating unit on and off in three minutes. 10. If a heating sample is placed in the case, use a power supply for the sample power control. Do not use the power supply directly. 11. Circuit Breaker, Temperature Super Temperature protector, providing the test equipment and the safety protection of the operator, please check regularly 12. The correct device wet ball gauze, in order to ensure the correct relative humidity measured 13. Absolutely prohibited test explosive, flammability and high Corrosive substances 14. Please read the controller instructions and related manuals before operating the machine
We know that the instruction manual is a guide for the use of the machine. It describes in detail how to install, operate procedures, maintenance methods, and simple troubleshooting and usage precautions. However, the operation training and technical guidance provided by the manufacturer's engineers cannot be ignored. Please keep in mind that precautions can help prevent the machine from malfunctioning due to improper operation. Proper maintenance can extend the life of the machine.
