Micrometer

Micrometer 75
100 mm

• accuracy: 0.01 mm
• operating temperature: 5^oC
  40^oC / 41F
  104F
• humidity effect: negligible below 80% relative humidity
• to take precise measurements in the range from 75 to 100 mm

Preparation for use:

• Clean the measuring surfaces and the guide
  use a cotton cloth, do not use solvents or acids
• Check the zero position and if necessary adjust with the supplied wrench so that the line labeled "0" on the drum coincides with the horizontal line of the scale

Method of measurement:

• the drum can be rotated only after unlocking the locating clamp
• spread the measuring surfaces to a distance slightly larger than the object to be measured
• then rotate with the drum to roughly set, and then continue tightening by turning the friction clutch knob
• then tighten with the drum. /li>
• stop tightening when the clutch operates, that is, further rotation of the knob will not cause rotation of the drum
• read the measurement result according to the measurement principle shown in the figure

It is recommended to fix the measured part or micrometer before starting the measurement. This will allow you to achieve the highest measurement accuracy.

It is also recommended that several measurements be taken so that an arithmetic average of the results can be obtained.
