Use the ratchet stop (if fitted) to finally close the 2 anvils together. Rotate the ratchet stop 1 to 2 revolutions to exert a constant measuring force In the closed position the zero position on the thimble should coincide with the horizontal line on the sleeve If the two lines do not coincide, small adjustments can be made by using the C spanner provided Insert the C spanner into the hole at the back of the sleeve and gently turn the sleeve in the direction required to achieve line up The micrometer is now set and ready for use Clean micrometers and check zero position regularly during use to ensure their continued accuracy After use always clean and replace the micrometer in its box
