Operation and selection principles of high and low temperature alternating test chamber

1. First turn on the main switch and turn it to ON.

2. If you are doing a humidity test, check the water tank to see if the water level is sufficient, otherwise add water. If you only do a high temperature test, remember to take out the wet ball gauze.

3. Turn on the instrument panel power switch (green POWER).

4. Press the touch screen to adjust the program or set the temperature and humidity parameters, and press ENT to end the input.

5. Place the sample. At this time, pay attention to the volume of the box. Don't put too many samples in too dense. The sample box must be about 10 mm between the boxes. Some customers have reported that when doing high-temperature experiments, because the box is placed There were too many samples, which blocked the airflow. Finally, the instrument smoked and emitted an unpleasant burnt smell, which almost caused a fire.

6. During the experiment, unless absolutely necessary, it is not allowed to open the door of the box to avoid accidents. You can press the LPS button on the panel to light up the light of the constant temperature and humidity test box and watch the samples in the box.

7. When the test equipment needs to do high temperature operation experiments, it can be powered by an external power supply through the side hole of the box.

8. When the test is completed, turn off the power of the instrument and switch the main switch. During high temperature experiments, wait until the temperature has cooled to a safe range before opening the door to take out the sample.
