Precautions for use:

Installation and grounding

The equipment should be placed in a dry and well ventilated environment, away from heat sources and areas with high humidity changes. During installation, it is necessary to ensure that the casing of the box is grounded to avoid the risk of electric shock. ‌

Operating Specifications

Avoid frequent opening and closing of doors: During the testing process, the number of times doors are opened should be reduced, and after opening the door, wait for more than 30 minutes for the temperature and humidity to stabilize. ‌

Power management: When testing heating samples, an external power supply is required and direct connection to the device power supply is prohibited. ‌

Safety protection: Wear insulated gloves during operation to avoid skin burns caused by high temperature air. ‌

maintenance

Regular cleaning: Clean the inner and outer surfaces of the equipment and keep them dry. ‌

Replace accessories: Regularly inspect and replace vulnerable parts such as filters and seals. ‌

Calibrate sensors: Regularly calibrate temperature and humidity sensors using standard instruments to ensure accuracy. ‌

Parameter Settings

Reasonably set temperature and humidity parameters according to experimental requirements to avoid frequent adjustments that may cause data bias. ‌

environmental control

Avoid stacking obstacles around the equipment to ensure smooth air circulation
