Daily low temperature and humidity test chamber maintenance and maintenance knowledge

Daily maintenance and maintenance of high and low temperature damp heat test box

The production of a device is perfect. If the individual or unit that uses it does not pay attention to maintenance and maintenance in daily life, the performance and service life of the device can be greatly reduced, just like a woman's face, and it can be properly maintained. People look radiant, equipment is the same, maintenance is done well, then the equipment can also have a good and stable operation.

---- Daily maintenance tips:

1) Remove internal impurities before operating the equipment.

2) The power distribution room should be cleaned at least once a year or more. When cleaning, vacuum cleaners can be used to suck indoor dust.

3) The exterior of the cabinet must also be cleaned more than once a year. Wipe with soap and water before cleaning.

4) Inspection and Maintenance of Humidifier The storage of water in the humidifier should be changed once a month to ensure that the water quality is clean. The humidifying water tray should be cleaned once a month to ensure smooth water flow.

5) When checking the operation of the over-temperature protector, set the maximum value of over-temperature protection by 20°C~30°C. When the temperature in the test chamber rises to the set point of the over-temperature protection, the heater power supply is stopped. The "OVERHEAT" over-temperature warning light is on but the fan is still running. If it is operated for a long time and left unattended, it must be checked before operation. Over-temperature protector is set properly [Wet ball over-temperature protector setting is 120°C].

6) Condenser dust removal The condenser should be maintained on a regular monthly basis, using a vacuum cleaner to suck dust from the condenser heatsink mesh or use high-pressure air to remove dust.

7) Wet ball test cloth replacement When the test cloth surface is not clean or hardened, or after the temperature control is done, the test cloth must be replaced before continuing the temperature and wet sphericity control. The test cloth should be replaced once in about three months. Wipe the Sensing Body with a cleaning cloth when replacing it. Clean the new test cloth first.

8) For the moving parts, lubrication should be performed according to the instructions, and the electrical control system should be regularly maintained and checked. These tasks are indispensable.
