Transport and Storage
1. Transport
When the equipment needs to be transported, it is recommended to use our company's instrument packaging wooden case and shock-absorbing materials to avoid unnecessary damage during transit and prevent unnecessary losses.
When the equipment is transported without a wooden case, stacking is not allowed. When using our company's packaging case, the maximum stacking layers allowed is two.
During transportation, the instrument panel should face upward.
2. Storage
The equipment should be placed indoors that is dry, dust-free, ventilated, and free from corrosive gases. Without wooden case packaging, stacking is not allowed.
When storing, the panel should face upward. Place moisture-proof materials under the equipment to prevent dampness.
