Precautions
1. In the process of operation, personnel should pay attention to personal protection and avoid electrical leakage or contamination of the eyes and mouth by the solution.
2. Input power AC220 + / -2%.
3. Please do not open the door when the sample is testing. After the test is finished or when the experiment fails to produce a fire smoke, open the fan to remove the smoke and then open the chamber door for the operation
4. The exhaust pipe should be out of the window
5. The power supply is applied to the three-pin socket with ground wire to ensure the reliable grounding.
6. Before the test, it is necessary to confirm whether the equipment is in the metering validity period,or the test is not allowed.
