Since the constant temperature and humidity test box is a kind of temperature and humidity inside the box body, it must not be opened during the operation of the test equipment to prevent the high temperature burn or frost injury of the test personnel in the test box. So there are six points to note in the process.
1. When the low temperature operation is completed, it is best to carry out the drying process at a temperature of 60 ° C for about 30 minutes and then open the door of the constant temperature and humidity test chamber, so as not to affect the measurement time during the subsequent test or cause the evaporator to freeze.
2. During the operation of the constant temperature and humidity test box, please do not open the door of the box unless you have to open it as a last resort, otherwise it may cause these undesirable consequences: high temperature and humidity impact outside the box; the inside of the box door remains High temperature; high temperature air may trigger a fire alarm and cause mistakes; the switch box body has some damage to the compressor during the experiment. Unless the test requires, it is not recommended that the customer frequently open and close the door during the experiment.
3. Circuit breakers and over-temperature protectors, which provide test products and operator's personal safety protection equipment, must be regularly checked in detail.
4. The installation position of the wet ball gauze must be accurate in order to measure the correct relative humidity.
5. The cabinet of the constant temperature and humidity test chamber is in operation, please do not check it with your hands to avoid danger of electric shock or injury by the fan.
6. Operators of non-constant temperature and humidity test chambers are not allowed to perform maintenance and inspection on constant temperature and humidity test chambers, and in addition to full-time personnel for inspection, professional electricians and circuit maintenance personnel are also required to prevent unintentional The personnel are energized and closed, causing the risk of electric shock.
