How to Read the Torque Value on a Torque Wrench?

[VonZane]

If it is a dial-type torque instrument, directly read the data indicated by the pointer as the measured value; if it is a socket with an auxiliary scale indicator, first read the scale value on the main scale, then add the value on the auxiliary scale or micrometer sleeve to get the measured value. Introduction to torque wrenches: 1. Select a torque wrench with an appropriate range: When using a torque wrench, first choose a wrench with a suitable range based on the requirements of the workpiece to be measured. The measured torque value should not be less than 20% of the wrench's range during use. A too-large range is not suitable for reinforcing small torque components, and a small-range torque wrench should never be used beyond its range. 2. Determine the preset torque value according to the required torque value of the workpiece: When setting the torque value, adjust the main scale line and the differential scale line to the desired torque value.
