ميكروميتر داخلي 25:0 مم YT-72300

Micrometer 0-25mm

• 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 0 to 25 mm

Preparation for operation:

• 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

Measuring machine

Method of measurement:

the drum can be rotated only after unlocking the locating clampspread the measuring surfaces to a distance slightly larger than the object to be measuredthen rotate with the drum to roughly set, and then continue tightening by turning the friction clutch knobthen tighten with the drum. /li>stop tightening when the clutch engages, that is, further rotation of the knob will not cause rotation of the drumread 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.
