3-2 f t + _ f u f e f ges + _ testing of test indicators, dial indicators and dial comparators all test indicators, dial indicators and dial comparators are subject to a final inspection in production on mahr measuring machines (865, 875 and optimar 100). the following, in ? din 2270 (test indicators) ? din 878 (dial indicators) ? din 879 (dial comparators) defined parameters, will be tested: deviation of reading from set-point value set-point reading local span of error plunger being pressed in plunger being let out diagram for the spans of error f e and f ges and hysteresis error of the measured value f u (example) diagram of the span of error f t (example) set-point reading deviation of reading from set-point value ? span of error f e span of error f e is the distance between the ordinates of the highest and lowest points in the deviation diagram either when the plunger is being pressed in (dial indicators, dial comparators) or in the case of excursion of stylus against measuring force (test indicators). ? total span of error f ges the total span of error f ge s is the distance between the ordinates of the highest and lowest points in the deviation diagram when the plunger is being pressed in and let out (dial indicators, dial comparators) or in the case of excursion of stylus against and with the same direction of measuring force (test indicators). the total span of error includes the hysteresis error of the measured value f u . ? local span of error f t span of error f t is the distance between the ordinates between the highest and lowest points in the deviation diagram, measured for a local measuring span of 10 scale divisions within 0,1 mm when the plunger is being pressed in (dial indicators, dial comparators) or in the case of excursion of stylus against measuring force (test indicators). ? repeatability f w repeatability f w is a characteristic for measured value fluctuations in measurements of the same measurand within the measuring span and with the same direction of movement of the plunger (dial indicators, dial comparators) or of the stylus (test indicators).
3-3 design features of mahr test indicators puppitast test indicators ? corrosion-proof due to satin-chrome finish on housing ? maximum sensitivity and accuracy provided by precision gears and pinions ? jewelled movement bearings ? overload protection provided by slip clutch ? low measuring force ? easy to read thanks to high-contrast, rotable dial face ? self-contained movement. this unit can be easily removed and quickly replaced for maintenance and repair purposes. ? insensitivity to magnetic fields ? box-type housing open on one side only ? bottom and side walls made of one piece. this shell totally encloses the movement and provides maximum protection against shock and damage ? the front end of the housing is of fork-shaped design with the stem of the stylus mounted in the fork to provide high stability. the precision alignment of the two bearings ensures maximum accuracy ? automatic matching to sensing direction, i. e. pointer always moves in clockwise direction, thus ensuring error-free reading ? rigid mounting ? mounting shank can move on three dovetail guideways which are integral parts of the sturdy housing ? they can be clamped at any desired point with a knurled nut. no tools are required. ? no plastic parts except for transparent cover over dial face

3-7 dial indicators design features of mahr dial indicators ? rising of measuring spindle by screw-in cable release ? protective housing only opens at the front. the housing is thus not simply a cylinder with a cap over it, but rather the back and side walls are machined from one piece. this shell totally encloses the movement and provides maximum protection against shocks and damage ? constant measuring force over entire range by virtue of compensation lever ? self-contained movement. can be removed and replaced quickly and easily for repair or maintenance purposes ? maximum sensitivity and accuracy ensured by precision gears, pinion and rack as well as by precision guide for measuring spindle ? tapered piece on mounting shank for easy insertion into mounting hole ? protective and lifter cap mounted on upper end of measuring spindle ? adjustable tolerance markers for setting tolerance limits ? corrosion-proof due to satin-chrome finish on housing and stainless, hardened steel for mounting shank and measuring spindle ? easy to read on account of high contrast dial ? simple fine adjustment with convenient knurled bezel ? shockproof movement on all dial indicators with the exception of the long-range model 810 v the rack is not located directly on the measuring spindle, but rather on a sleeve which floats on the spindle. the shocks to which the spindle is subjected in everyday use are therefore not transmitted to the rack and mechanism. in the event of shocks, the sleeve lifts off and follows slowly due to spring force. the movement is thus reliably protected even against severe shocks.

3-15 dial comparators design features of mahr dial comparators ? constant measuring force over entire range due to built-in compression spring ? shockproof movement. the precision ball of the first transmission lever rest on the lapped saphire plane surface of the upper end of the measuring spindle. if the spindle is subject to severe impact, the plane surface is automatically raised, thus preventing transmission of the shock to the movement ? box-type housing only open at the front ? bottom and side walls made of one piece. this shell totally encloses the movement and provides maximum protection against shock and damage ? simple fine adjustment by way of lockable screw ? self-contained movement. this unit can be removed and replaced quickly and easily for repair or maintenance purposes ? maximum sensitivity and accuracy are ensured by jewelled bearings of movement in conjunction with precision gears and pinions ? corrosion-proof by virtue of hardened, stainless steel mounting shank and measuring spindle ? protection of ball guide against contamination by means of a sleeve seal ring which is provided with a groove for mounting slip-on rubber bellows to prevent the ingress of splashwater ? drip-proof version available on request. features rubber bellows at measuring spindle, sealed screws and splash guard cover ? measuring spindle mounted in high- precision ball guide prevents tilting and virtually precludes friction and play. the extremely low level of friction makes for high measurement accuracy and minimal hysteresis ? dial comparators with ball guide are particularly insensitive to lateral forces acting on the spindle (dial compa- rators 1010 and 1050 feature high- precision sleeve bearings for the spindle) ? easy to read due to clear-cut scale ? pointer moves over limited sector ? adjustable tolerance markers facilitate setting and observation of tolerance limits ? raising of measuring spindle either by way of screw-in cable or lifting knob
