Operation method of constant temperature and humidity test chamber

The operating method of the constant temperature and humidity chamber, the touch screen of the constant temperature and humidity chamber is imported from Korea, the LCD touch panel in Chinese and English liquid crystal display, the screen dialogue input data, the temperature and humidity can be programmed at the same time, the backlight is adjustable in 17 segments, and the curve Display, set value/display value curve. The temperature and humidity curve can be displayed on the screen. Various alarms can be displayed separately. When a fault occurs, the fault can be displayed on the screen to eliminate the fault and eliminate the misoperation. Multiple groups of PID control functions, precise monitoring functions, and display data on the screen. The operation of the constant temperature and humidity box program of Coside Instrument Company:




a) Select "Program Run" in the mode selection screen, enter the "Program Run" screen → click "Edit" → enter the process selection screen → click "Edit" → enter the process edit screen → click "Add" → enter the new program name.
b) Enter the actual value required for the test in the boxes of time, temperature, humidity, temperature waiting, humidity waiting, and cycle times.
c) Click "Return" in the upper left corner → return to the process selection screen → select the program name to be run → click "OK" → pop up (replace) dialog box → click "OK" to automatically return to the program running screen → click "Run" → A dialog box (confirm whether to start the program run) pops up → click "OK" to start the program run.


Constant temperature and humidity test chamber controller system capacity: 150 programs × 1500 segments can be logged in, the number of segments can be divided arbitrarily, and the programs can be connected freely.
Cycle setting: 9999×999 cycles can be executed, and 5 independent partial cycles can be cut out.
Control method: adopts intelligent forward and reverse two-way synchronous output, and contains advanced slope control logic.
Data setting: touch-sensitive dialog box setting mode, easy and clear operation, built-in directory data management system.
Curve drawing: When the temperature, humidity, and time data are set, they can be converted to the set curve immediately, and the actual operation curve can also be drawn during operation.
Time signal: 3 sets of time control output interfaces, with 10 time control modes, to facilitate the execution of external drive components start/stop time planning.
Final temperature: When the test is completed, you can choose to return to normal temperature to facilitate the removal of the test object.
Safety inspection: 15 full-featured system inspections to ensure the safe operation of the machine. Failure time, items and troubleshooting measures can be automatically displayed.
Exception traceability: It can display historical data of recorded failures, such as statistical records of the cause and time of occurrence of failures in the past.
External protection: The electronic over-temperature protection device independent of the main controller can set the temperature upper limit protection of the tested object.
Communication interface: standard communication interface device, which can be connected with a personal computer (PC) at the same time for multi-computer control and management.
The constant temperature and humidity chamber has been getting closer and closer to us with the development of science and technology, but compared with the temperature shock chamber, the constant temperature and humidity chamber can achieve instantaneous extremely high temperature or extremely low temperature. Compared with the temperature shock chamber, the constant temperature The operation of the constant humidity chamber is not simple. You still need to pay attention to many details during the operation, otherwise it will directly lead to inaccurate test results and even cause equipment failure.
1. When the constant temperature and humidity chamber is being tested, the sample must be placed in the middle of the chamber. The air duct cannot be blocked or placed against the wall. The distance should be at least 5mm.

2. If there are a lot of test samples, spread the test sample on the sample rack and leave a gap in the middle to avoid uneven sample test.

3. If the constant temperature and humidity chamber needs to be connected to an external power supply, connect the wires to the side of the test hole uniformly, and the wires should not be entangled.

In addition to the three more important points introduced by the editor, there are many other small details that need to be paid attention to when using the constant temperature and humidity test chamber. Since the door of the chamber is closed under normal conditions during the test, the staff cannot see the inside of the test chamber and the location of the test sample, we must pay attention to its location when placing the test sample.
