5. The independent glass front door observation window is transparent and beautiful, which is convenient to observe the changes of the items in the box. The magnetic rubber seal is used, and the door is easy to open and good in sealing performance.

6. Ultrasonic humidification is adopted, the humidification and temperature control are stable, the humidity fluctuation range is ±5-8℃RH, and the machine has a water shortage and power off function to prevent the machine from burnout due to water shortage.

7. The machine has multiple safety measures, such as compressor overheat protection and instrument failure protection, to ensure the safety of the tests.

8. The functions of printer, 485 interface, U disk storage, SMS alarm and so on can be additionally set.

Operation Method

1. Overview

The controller adopts the temperature self-adaptive control technology for temperature control, and can be used to simulate the natural environment (temperature and humidity).

The power supply of the humidifier must be connected to the humidifier socket at the bottom of the left side of the box body. The humidifier shall be connected to the left side of the box body with a hose. Humidification shall start when the temperature reaches the set temperature. The humidifying function does not start when the temperature rises for the first time.

2. Functional specifications

The system will return to the main page without operation within 30s. The buzzer will ring for 30s after the operation ends. When the buzzer rings, click any key to silence the sound.

3. Set the state

Turn on the power switch for about 3 seconds, the machine can normally display the temperature. The corresponding window of SV displays end, long press the "increase" key for about 2 seconds, and the machine will normally operate.

On the page of machine operation, click "Set key" to enter the setting state of cycle and number of segments. The set value of cycle flashes and can be modified by the "increase key" or "reduce key" (the cycle is generally set to 0 cycle). Press the "Set key" again, and the set value of the number of segments flashes and can be modified by the "increase key" or the "reduce key". Press the "Set key" again to enter the setting state of each period of time, temperature and humidity, and the corresponding value can also be modified by the "increase key" or "reduce key". After setting the corresponding period, number of segments, temperature, humidity and time, click the set key to save and exit, and then the machine starts to run.

In the setting state, click the return key to return to the setting of the previous parameter, and the selected parameter value will flash and be displayed. Short press the exit or set key to exit the setting state, save parameters and power failure memory.

Note: One cycle means that the controller runs from the first segment to the Nth segment (the number of segments required by the customer) for one cycle. When the cycle is set to 0, it means that the controller is located in the continuous working state.

Attention
