Claims
- 1. A method for calibrating a measuring device, said measuring device including displacement means disposed on one side of a housing interior, a dial indicator face disposed on an opposite side of said housing interior, and a movement mechanism disposed therebetween, said movement mechanism comprising an axially movable shaft member supported in said housing interior, said shaft member having a first end disposed adjacent said displacement means and a second end including a pointer adjacent said dial indicating face, a spring member attached at one end to said shaft member and at an opposite end to a support, said method including the steps of:
- presetting the axial distance between said spring ends as attached to said axially movable shaft and said support to a predetermined axial length so as to affect the amount of rotation of said pointer for a given movement of said displacement means; and
- rotating said shaft and said support to align said pointer to a null position relative to said dial indicator face.
- 2. The method as recited in claim 1 wherein said presetting step includes the steps of rotating a first adjustment member engageable with said support and coaxial with the axis of said spring member.
- 3. The method as recited in claim 2 wherein said presetting step includes the step of accessing said first adjustment member through an opening in said dial face without requiring disassembly of said measuring device.
- 4. The method as recited in claim 2, wherein said rotating step includes the step of rotating a second adjustment member after said presetting step.
- 5. The method as recited in claim 4, wherein said first and second adjustment members are coaxial to one another, in which each of said members are accessed through said dial face opening.
- 6. The method as recited in claim 5, including subsequent presetting and rotating steps, each of said steps being performed without requiring disassembly of said measuring device.
