Lever Outside Micrometer* 0-150mm
Features:
->Suitable for precise measurement of outer diameter (direct measurement or comparative measurement).
-> The movable measuring anvil is connected to a high-precision “indicator” with high measurement accuracy and measurement efficiency.
-> Carbide measuring surface.
->Powder metallurgy dark chromium ruler frame (≥50 steel ruler frame)
->Adjust the zero position: Turn the micrometer to the zero position, and the pointer should turn to the vertical direction of the center line of the moving anvil and coincide with the zero scale of the dial; if the pointer does not coincide with the zero scale of the dial, rotate the case with a screwdriver to adjust Zero mechanism, turn the dial to make it coincide. The range of zero scale rotation of the dial is within the vertical plus or minus 10 divisions of the center line of the moving anvil, and exceeding this range is a tolerance.
->Comparative measurement: Turn the differential tube to the nominal size of the part under test, then tighten the locking device, place the block group (equal to the nominal size) between the two measurement surfaces, and press the knob a few times. When the pointer is stable, turn the adjustment The zero mechanism allows the zero mark of the dial to coincide with the hands and stabilizes, and then the measurement can be performed.
