Mechanical Micrometer 50-75Mm/0.01Mm YT-72302 YATO

Mechanical Micrometer 50 - 75 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 50 to 75 mm

Preparation for Operation:

• Clean the measuring surfaces and guide using 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 the drum to roughly set, and continue tightening by turning the friction clutch knob.
• Stop tightening when the clutch operates; 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 the micrometer before starting the measurement to achieve the highest measurement accuracy. It is also advisable to take several measurements to obtain an arithmetic average of the results.
