Damage may causefailure or poor accuracy.Do not disassemble or modify.It may damage Gauge and cause pooraccuracy.If Bezel Clamp Screw is removed, internalcomponents may come loose and becomemisaligned causing product failure.Do not shock Probe.Rapid motion, or lateral force may damageGauge and cause poor accuracy.Measurement DirectionPREPARATION - MountingDial Indicator must be securely mounted such as on a comparator stand or magnetic base.Please follow these guidelines.Make sure Gauge holder is rigid.Holder must be sufficiently secure to prevent deflectionfrom the weight of the Gauge.Holder must be rigid enough to hold Gauge and not tolift from measurement force.Holder support arm should be as short as possible toprevent deflection.Deflection or lifting will cause measurement error, suchas origin position error and inaccuracies in measuredreading.Dial Gauge must only be attached by Dovetail or Stem.Mounting of gauge by other than Stem or Dovetail will causeinaccuracy and product damage.Slightly LoosenAttach Mounting Stem.Loosen the Stem mounting bracket and slide thegroove onto the Dovetail in the desired position.Tighten the Stem to secure. (Choose a stem withdiameter to match the Gauge Holder you plan touse.)Confirm that the Probe and stem are securewithout any play.If they are loose, tighten to secure.Attach the Indicator Gauge to the Holder.Please attach by the Stem only.Confirm that the pointer moves freely.Bring the Probe into contact with the workpiece, andgently raise and lower the gauge while checking themovement. Confirm that the pointer returns to initialposition when raised.Make sure the Probe is parallel to themeasured surface, and perpendicular to thedirection of the measurementIf probe is not positioned properly, the measurementwill be inaccurate and operation may be faulty.Set Up Reference Part.Position the reference Part with the measuredsurface parallel to the probe and perpendicular to thedirection of the measurement. Bring into contact withthe probe, but use care that the part does not bumpthe probe from the side.Set the Origin.Adjust the gauge mount or rotate the Bezel to set theGauge to 0.Remove the Reference Part and Measure theWorkpiece.Remove the master with care not to shock the gauge.Replace with the workpiece and read the scale.Position the probe on the workpiece.Position the Part with the measured surface parallel to the probe and perpendicular to the direction of themeasurement. Bring into contact with the probe, but use care that the part does not bump the probe from the side.Set the Origin.Adjust the gauge mount or rotate the Bezel to set the Gauge to 0.Move the workpiece and read the scale.Move the workpiece slowly while reading the position of the pointer on the scale.HOW TO USE - Parallelism, Flatness, Runout, etc.HOW TO USE - Comparison MeasurementsTROUBLESHOOTINGOrigin position shifts during measurement.Temperature changes during measurement can cause repeatability error. Please try the following solutions:Use in location with constant temperature.When taking measurements, periodically adjust zero point using a Master reference to correct for temperatureinduced drift.Make sure the Stem is not loose, and tighten if necessary.Measurement is not stable, or measurement accuracy is poor.Probe may be worn; a worn Probe will affect accuracy. Periodically check for wear, and replace if wear is affectingmeasurement accuracy.DovetailgrooveHOW TO USE - PreparationSPECIFICATIONSRemove any dust or dirt after use. Do not lubricate.Wipe any contamination from Probe and moving surfaces usinga dry cloth, or cloth moistened with alcohol.To clean other surfaces, wipe with a soft dry cloth, or a clothmoistened with a mild cleaner.Check for wear of Probe tip.Measurement accuracy will be affected by worn Probe.Regularly check for wear and replace Probe if worn.Store in provided case in a cool, dark, and dry location.During storage, make sure there is no force on the Probe (suchas pushed in, or lateral force.)Keep away from moisture and direct sunlight, and secure fromunauthorized personnel.Use only factory approved Probe. Using alternate probemay cause error.Always perform calibration after replacing Probe.AFTER USE CARE, STORAGECALIBRATIONTo maintain measurement accuracy, periodic calibration isrecommended.(For reference, we recommend a calibration interval of 3~4 monthswhen used in a factory.)Outside Japan, Please contact distributor or place of purchase toinquire about calibrations services.Niigata seiki Co., Ltd.5-3-14, Tsukanome, Sanjo, Niigata, Japan, 955-0055Tel. : +81-256-33-5522 Fax. : +81-256-33-5518MAIL intl.sales@niigataseiki.co.jpURL http://www.niigataseiki.co.jp
