The artificial climate simulation system of the comprehensive experimental chamber is to place the test piece at the specified temperature, humidity, and oscillation, and observe the product's high temperature resistance, high and low temperature resistance, humidity resistance, and anti oscillation function.

The artificial climate simulation system of the comprehensive experimental chamber is to place the test piece at the specified temperature, humidity, and oscillation, and observe the product's high temperature resistance, high and low temperature resistance, humidity resistance, and anti oscillation function. The three comprehensive test boxes have a relatively large volume and are inconvenient to move, as well as the experimental box, heating system, electrical control cabinet, and refrigeration unit; The circuit of the electrical control cabinet is quite complex, and when a malfunction occurs, it usually leaves customers at a loss. In order for customers to solve the problem in a timely manner without affecting the work progress, the following is a quick method to identify the malfunction of the three comprehensive test box and its solution: the abnormal humidity inspection process of the three comprehensive test box: ① Please check whether the pipelines in the computer room are too dirty, causing uneven water flow; ② Please check if there is water in the upper water tank. If there is no water, then check if there is water in the lower water tank; ④ Please check if the under water and over temperature protector in the control room is set in a standardized position; ④ Please check if the solid-state relay in the humidity part is burned out and short circuited: If the heater is not burned out, please use a three way electricity meter to communicate the voltage level. Set the voltage level to 600 volts, separate the red and black rods from the solid-state relay marked with line number H, and communicate on both sides. Set the humidity setting value in the humidity part to 0%. At this moment, the indicator light of the solid-state relay in the humidity part will not light up. If the measured voltage value does not change, Maintaining below 10V indicates a short circuit condition when the solid-state relay is burned out. Alternatively, set the humidity setting to 0% first, and then check if the humidification bucket in the machine room is boiling water.
