Wuhan High and Low Temperature Test ChamberVolume selection method:
1. Based on the size of the customer's product, taking a product measuring 30CM in length, 30CM in width, 30CM in height, and 40CM in height as an example, a testing machine with an inner box size of 40cM in length, 40CM in width, 40CM in height, and 50cm in height can be selected as more suitable. The reason for choosing a size of 10CM is that the product is easy to store and requires a certain amount of space for even air circulation during equipment operation. Of course, being too big can lead to wastage of resources and an increase in costs.
2. Based on the quantity of customer products, taking a single product with a length, width, and height of 10CM and a quantity of 10 pieces placed flat as an example, a testing machine with an inner box size of 110CM in length, 20CM in width, and 20CM in height can be selected. However, this is not the case and mainly depends on the way the products are placed. They can be placed flat, stacked, or both flat and stacked at the same time. Simultaneously placing flat and stacked according to the customer's testing situation is the most common and reasonable, because the high and low temperature alternating humidity test chamber produces regular shapes without wasting testing space.
According to the performance of the product, there are two common types of performance:
A. For products with heat generation, the temperature range should be lower than the actual required temperature based on the heating power. The size of the inner box should also be slightly larger to facilitate temperature storage. Especially during low-temperature testing.
B. For products that can be placed diagonally or irregularly during testing, taking the 80L high and low temperature alternating humidity test chamber as an example, the actual inner box size is 40cm wide, 50cm high, and 40cm deep. According to the triangle formula, the slope of the height and width calculation exceeds 60cm. So products that can be tilted, with a length of 50cm, width of 30cm, and height of 30cm, can also choose this type of high and low temperature testing machine. Of course, this selection method is not applicable to all products, and customers should decide based on their own product situation when making a choice. Most national industry standards are for flat and stacked placement. Especially for products that are prone to damage when placed diagonally, it is recommended to choose based on the above two points.

Alarm handling method:
1. If the environmental environment is too high, turn on the equipment and use indoor air conditioning or open doors and windows for ventilation to reduce the environmental environment to below 35 degrees and maintain it at around 25 degrees, or clean the impurities and dust in the condenser and press the reset button on the overcurrent protection to reset.
2. The processing method is the same.
3. The processing method is the same as above, the high-voltage reset button automatically resets.
4. The processing method is the same as above, the high-voltage reset button automatically resets.
5. Check if there is an underphase and reverse phase, and if the power supply is normal. If there is an underphase, a multimeter is needed to check the voltage between each phase sequence. If there is a reverse phase, check if the phase sequence is misaligned when the circuit is installed. Swap any two phases in the live wire to eliminate the fault.
6. Is the temperature set to exceed the maximum temperature range of the device? Please refer to the device manual for the specific temperature range.
7. When the water supply system is abnormal and the water tank is short of water, check the water cup, whether there are impurities in the water tank, whether there are air blockages in the water pipe, and whether the water level in the water tank is lower than the lowest water level value for equipment use. Clean and wipe the water cup and impurities in the water tank, squeeze the bubbles in the water pipe by hand to discharge them outward, and add an appropriate amount of pure water to the water tank.
