- More accurate in one-handed operation: inexperienced operators measure significantly more accurately with the new micrometer.
- Ratchet function works both from the thimble and the speeder.
- Rotating the thimble/speeder when workpiece is between the anvil and spindle causes the ratchet mechanism to operate and apply a constant measuring force to the workpiece.
- Clearly aubible ratchet operation for reassurance that measurement is being performed at constant, preset force.
