Precautions When Using The Micrometer; Precautions When Measuring - Starrett 436.1 Manual Del Usuario

PRECAUTIONS WHEN USING THE MICROMETER

• Clean the measuring faces with a smooth cloth or chamois.
• Do not expose the micrometer to direct sunlight or extreme temperatures.
• Avoid mechanical shocks so as not damage the instrument.
• Do not disassemble the micrometer.
• Do not use compressed air on the micrometer; this can contaminate
the spindle.
• After using the micrometer, clean it and apply a thin coat of special
lubricant for instruments on the measuring faces and spindle to
avoid oxidation.
• Keep the micrometer, preferably, in its own original package.

PRECAUTIONS WHEN MEASURING

• Do not measure a rotating part; it is dangerous and causes the faces
in contact to wear.
• Do not apply excessive pressure when measuring. Use the ratchet or
thimble to obtain the appropriate measuring pressure.
• Parallax Error: Be careful when measuring to avoid a parallax error.
This error occurs when the observation point is not perpendicular to
the display. Take the reading perpendicularly to the thimble, sleeve
and vernier lines.
