The programmable constant temperature and humidity test chamber is a kind of high precision constant temperature and humidity test equipment, which is often used in laboratories and production lines in the fields of materials, електроника, хемијски, храна, medicine and so on. Here are some common problems you may encounter and calibration methods:

П&А
Temperature or humidity readings are inaccurate.

The temperature or humidity is unstable.

Уређај није равномерно загрејан или хлађен.

Уређај цури или је капацитет резервоара недовољан.

Дошло је до грешке у раду програма.

Метода калибрације
Калибрација температуре: Place the thermometer in the test chamber and set the chamber to a known temperature. После извесног времена, the thermometer reading is compared with the temperature reading displayed in the test chamber. Ако постоји разлика, потребно је подешавање калибрације. Calibration can be done through program Settings or by adjusting the sensor circuit.

Humidity calibration: Use a humidity calibrator to place it in the test chamber and set the test chamber to a known humidity. После извесног времена, compare the humidity calibrator reading with the humidity reading displayed in the test chamber. Ако постоји разлика, потребно је подешавање калибрације. Calibration can be done through program Settings or by adjusting the sensor circuit.

Калибрација униформности опреме: Place several thermometers or hygrometers inside the test chamber and set the test chamber to a known temperature or humidity. Након чекања одређеног временског периода, упоредите очитавања на свакој тачки мерења да видите да ли су конзистентна. Ако постоји разлика, потребно је подешавање калибрације униформности. Calibration can be done through program Settings or by adjusting the sensor position.

Калибрација капацитета резервоара опреме: Fill the tank in the test box with water and record the water capacity. Then set the test chamber to a certain humidity, мера за одређено време, а затим излити резервоар и забележити преостали капацитет воде. Subtract the remaining water capacity from the previously recorded water capacity to obtain the amount of water used by the test chamber at this humidity. Ако количина коришћене воде није у складу са капацитетом у спецификацији, потребно је подешавање калибрације капацитета резервоара. It can be calibrated through program Settings or by adjusting the tank capacity.

Подсећамо вас: the programmable constant temperature and humidity test chamber needs to be calibrated and maintained regularly, and the program needs to be updated and maintained. Program error is one of the common problems. It is necessary to maintain the program in time to ensure the correctness and stability of the program. Додатно, it is recommended to follow the equipment’s operating manual and

Maintenance guidance provided by the manufacturer to carry out maintenance, regularly clean the inside of the equipment, check the performance and condition of heating, хлађење, контролу, сензори и друга опрема, timely replacement or repair of faulty parts. Додатно, you are advised to power off the device before maintenance and wait until the device cools down to ensure safety.

Precautions for use
In the process of using the programmable constant temperature and humidity test chamber, треба напоменути и следеће тачке:

Reasonable arrangement of sample placement, to ensure that the sample can be subjected to uniform temperature and humidity distribution.

Do not accumulate too much debris or samples inside the test chamber to avoid affecting the operation of the equipment and the accuracy of the data.

According to actual needs, the temperature and humidity range and accuracy of the test chamber should be reasonably selected to avoid inaccurate test data due to mismatch of equipment parameters.

Пре теста, pre-heat or pre-cool to ensure that the equipment can meet the required temperature and humidity conditions.

У процесу коришћења опреме, the temperature and humidity changes and test data are recorded in time, and analyzed and processed as required.

Укратко, the constant temperature and humidity test chamber and the programmable constant temperature and humidity test chamber play an important role in the laboratory and production line, but at the same time, attention needs to be paid to the use and maintenance of the equipment to ensure the stability of the equipment and the accuracy of the test data.
