When detecting the landing door opening, the reference plane G is contacted with one landing door plane, a certain force (150N) is applied, and the largest opening gap of the landing door is measured.
When the gap is detected, the reference surface F is contacted with planes such as a landing door, a sill and the like, the measuring direction is vertical to the reference surface, and the maximum gap value is measured at different positions.
When the meshing angle is detected, the reference surface A is tightly attached to the lower end surface of the locking roller of the layer door, the reference surface A is perpendicular to the surface of the roller, meanwhile, the angle ruler is rotated to enable the reference surface H to be in contact with the movable roller and the static roller of the layer door, the angle value is read on the main ruler, and the display value is the deflection angle of the movable roller.
