Those things that can program high and low temperature boxes

1. When the low temperature operation is completed, it is better to carry out the drying treatment at 60 ° C for about 30 minutes before opening the door to avoid affecting the measurement time in the subsequent test or causing the evaporator to freeze without the phenomenon of low temperature or humidity out of control;
2. When the constant temperature and humidity chamber is running, please do not open the door casually unless it is necessary to open it, because opening the door during operation may cause the following adverse consequences:
(1) High temperature moisture rushed out of the box and injured (2) The inside of the box door still maintains high temperature and causes damage to the operator. (3) High temperature air may trigger a fire alarm and cause errors. (4) The switch box exists to the compressor during the experiment. A certain amount of damage mentioned above: Unless the test requires, it is not recommended that the customer frequently switch the door during operation.
3. When using the constant temperature and humidity chamber, be sure to ensure the safety and grounding, and ensure that the ground wire is insulated from the neutral wire to avoid static induction or damage to the equipment;
4. Leakage circuit breaker and over-temperature protector This kind of protection equipment that provides test items and the personal safety of the operator must be regularly checked in detail;
5. The installation position of the wet ball gauze must be accurate (generally hanging on the nearest temperature sensor above the head) to measure the correct relative humidity;
6. During operation, do not touch the hand to avoid danger of electric shock or injury by the fan;
7. Non-local workers are not allowed to repair and inspect the machine. In addition to the full-time staff, there must be professional electricians and circuit maintenance personnel to prevent unsuspecting personnel from energizing and closing. This creates a risk of electric shock.

The basic troubleshooting methods for constant temperature and humidity chambers are as follows:
1. When the humidity of the constant temperature and humidity chamber has been relatively high and cannot be lowered: please check if the wet ball gauze is properly mounted. Please check if the wet gauze is aging and cannot absorb water.
2. When the constant temperature and humidity chamber (applicable to all high-power equipment) often trips: Please check whether the fire (phase) / neutral line and ground (case) are connected (small resistance)
