Micrometer 25 - 50 mm

• accuracy: 0.01 mm
• operating temperature: 5^oC - 40^oC / 41F - 104F
• humidity influence: negligible below 80% relative humidity
• to take precise measurements in the range from 25 to 50 mm

Preparation for work:

• Clean the measuring surfaces and 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

Measuring machine

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 engages, 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
