Operation:
Before use, the measured surface and the working face of the level meter must be scrubbed clean.
When in use, the heat source and air flow should be insulated and the temperature should be kept as constant as possible.
When the level gauge is placed on the measured surface, it must wait for the bubbles to be stationary before it can be read.
When reading, it should be observed vertically to avoid parallax.
After use, rust-proof treatment should be carried out.
When placed, attention should be paid to shock-proof and moisture-proof.
