Mechanical Micrometer 25-50Mm/0.01Mm YT-72301 YATO

The YATO Mechanical Micrometer model YT-72301 is designed for precise measurements of linear dimensions, featuring a measuring range of 25-50 mm and an accuracy of ±0.01 mm.

Key Features:

• Accuracy: 0.01 mm
• Operating Temperature: 5°C - 40°C (41F - 104F)
• Humidity Influence: Negligible below 80% relative humidity
• Effective for taking precise measurements in the range of 25 to 50 mm

Preparation for Use:

• Clean the measuring surfaces and guide with 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.

Measurement Method:

• The drum can be rotated only after unlocking the locating clamp.
• Separate the measuring surfaces to a distance slightly larger than the object to be measured.
• Rotate the drum to roughly set, then continue tightening by turning the friction clutch knob.
• Stop tightening when the clutch engages, meaning further rotation of the knob will not cause the drum to rotate.
• Read the measurement result according to the measurement principle shown in the figure.

It is recommended to secure the measured part or micrometer before starting the measurement to achieve maximum accuracy. Additionally, taking several measurements is advisable to calculate an arithmetic average of the results.
