F-89FMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.  FF-89PositionRemarksVertical position (contact point downward)—Lateral position(spindle horizontal)If measurement is performed with the lateral position or upside-down position, the measuring force is less than in the vertical position. In this case be sure to check the operation and repeatability of the indicator or digital display.For guaranteed-operation specications according to positions of digital indicators and dial gages, refer to the product descriptions in a general catalog.Upside-down position (contact point upward)Stem mounting MethodNote• Mounting hole tolerance: ø8G7(+0.005 to 0.02)• Clamping screw: M4 to M6• Clamping position: 8mm or more from the lower edge of the stem• Maximum clamping torque: 150N·cm when clamping with a single M5 screw• Note that excessive clamping torque may adversely affect spindle movement.• Mounting hole tolerance: ø8G7(+0.005 to 0.02)Lug mountingMethodNote• Lugs can be changed 90 degrees in orientation according to the application. (The lug is set horizontally when shipped.)• Lugs of some Series 1 models (No.1911T-10, 1913T-10&1003T), however, cannot be altered to horizontal. • To avoid cosine-effect error, ensure that any type of gage or indicator is mounted with its spindle in line with the intended measurement direction.8mm or moreM6 screwPlain washer5M2.5 × 0.45Incomplete thread section shall be less than 0.7mmM2.5 × 0.45, depth 7mm ø3 counterbore, depth 1mmspindleThe specication in the range of 0.2 mm from the end of the stroke is not guaranteed for digital indicators. When setting the zero point or presetting a specic value, be sure to lift the spindle at least 0.2 mm from the end of the stroke.GroundGroundGround0.2mm■ Mounting a Dial gageClamping the stem directly with a screwClamping the stem by split-clamp fastening■ Contact point• Screw thread is standardized on M2.5x0.45 (Length: 5mm).• Incomplete thread section at the root of the screw shall be less than 0.7mm when fabricating a contact point.■ Measuring orientation■ Setting the origin of a digital indicator■ Care of the spindle•Do not lubricate the spindle. Doing so might cause dust to accumulate, resulting in a malfunction.•If the spindle movement is poor, wipe the upper and lower spindle surfaces with a dry or alcohol-soaked cloth. If the movement is not improved by cleaning, contact Mitutoyo for repair.•Before making a measurement or calibration, please conrm if the spindle moves upward and downward smoothly, and stability of the zero point. 0.2mm
