3:1
Leverage indicator table dialtestindicators(levertype)
The mechanical transmission system is used to convert the swing displacement of the lever probe into the angular displacement of the pointer on the dial, and the dial is used to measure the readings:
Measuring appliances:
4 Design features
4:1 Overall design characteristics
4:1:1 The overall design and manufacturing process of the lever indicator should be able to ensure that the measurement characteristics of the lever indicator in various operating directions are consistent with
The requirements of this standard:
4:1:2 Unless otherwise specified, the swing direction of the lever indicator stylus should be perpendicular to the stylus axis and in the same direction as the stylus swing direction:
In the same plane, as shown in Figure D:1: If it is used at other angles, the displayed value should be corrected (see Appendix D):
