German horse Er (appearance of calibrating of the 826PC that metric equipment company produces Mahr) gauge block is OK and fast, reliable the each precision index of ground calibrating gauge block, it applies to the precision calibrating that gauge block manufactory undertakes gauge block product leaves factory already, also apply to use branch the periodic calibrating to gauge block. The base of the instrument and perpendicular pillar are cast-iron the integral part that makes, via special ageing treatment, function stabilizes changeless form. Inductance of head bracket along with is measured to measure slideway of head edge high accuracy to make the same score slippery shift to come on handwheel adjustment measure the place. All be put on workbench face by check gauge block and referenced gauge block, the adjustment on the right side of base is used in measuring a process knob operates, ensure workbench moves smoothly, undertake metrical to 5 measurement point. is measured is to use fluctuation sensor of inductance of two high accuracy comes true. Those who measure a head is adjustable promote with vacuum implement control. Gauge block of reference of the preexistence when measuring (classics calibrating is foregone dimension) center collects a numerical value, next ordinal the numerical value that is being gone up to collect 5 to nod by check gauge block, be worth these 5 what go up with referenced gauge block to be measured so that the value undertakes comparative, attainable by length of the central length deviation of check gauge block, center go up deviation of the deviation and variation of next deviation, length, parallelism that estimate a range. Measure an outcome by reading of the Millitron1240 that holds type of pressing with a finger and digital type concurrently to show indication watch, input the computer through serial interface, via computation and assess, print an one calibrating report with whole share automatically. The influence that spends to prevent handlers person temperature, in the instrument the front and flank can place the polypropylene glass that has special and adiabatic effect to protect screen. The instrument still contains attraction implement, with the gauge block that takes small measure at putting. The measurement of instrument limits is 0. 5mm ～ 170mm, valid area is workbench 60mm × 55mm, measure repeatability to be ± 0.
