Standard-attached inspection certicate includes inspection data.•We issue paid-for inspection certicates for horizontal or opposite posture if required.•It is said that, for evaluation of the compatibility to the specications, JIS B 0641-1 or the criteria where the internationally-recognized specication range and the OK range are equal shall be applied. Also, it is said that the uncertainty is preferred to be evaluated based on ISO 14253-2 and ISO/IEC Guide 98-3. Therefore, we perform shipping inspection of dial indicators inclusive of the uncertainty of calibration as in the past.Dial test indicator (lever type) Standard B7533: 2015 (Extract from JIS/Japanese Industrial Standards)No.Item.Measuring methodMeasuring pointEvaluation methodDiagram1Error of indication over a range of Measuring rangeHolding the dial test indicator (lever type), dene the reference point at near the contact point resting point where the indication and error of indication is set zero.Then, move the contact point in the forward direction and read the error of indication at each measuring point.Next, after moving the contact point for more than three graduations from the end of the measuring range, move the contact point in the backward direction and read the error of indication at the same measurement point in the forward direction.(The forward direction is the direction against the measuring force to the contact point of the lever-operated dial indicator; the backward direction is the measuring force applied direction.)Per 10 graduations in the forward and backward direction from the reference point to the end point.Obtain the difference between the maximum and the minimum values of indication error of all measurement points in the forward direction.2Error of indication over a range of 10 scale divisionsIn the forward direction from the reference point to the end point, obtain the maximum difference of the indication error among the adjacent measurement points per 10 graduations.3Error of indication over a range of One revolutionIn the forward direction from the reference point to the end point, obtain the maximum difference of the maximum and the minimum indication errors to be read by the zero-point xed method over the measuring range per 1 revolution.4HysteresisObtain the maximum difference in reference to the indication error at the same measuring point in both forward and backward directions among all the measurement points.5RepeatabilityHolding the dial test indicator (lever type) with its contact point parallel with the top face of the measuring stage, move the contact point quickly and slowly ve times at a desired position within the measuring range and read the indication at each point.At arbitrary points within the measuring rangeObtain the maximum difference of the ve measured values.6Measuring forceHolding the dial test indicator (lever type), move the contact point in the forward and backward directions continuously and gradually, and read the measuring force in the measuring range.Reference point and end point within the measuring rangeObtain the maximum and the minimum values in reference to the measuring force.Dial test indicator (lever type)SupportingstandMicrometer head orlength measuring unit Dial test indicator (lever type)SupportingstandDial test indicator (lever type)Top pan type spring scale  F-95
