Structure and function



(1) The instrument consists of the composition of the base, legs, par, dial gauge. See attached map.

(2) the base V-shaped groove structure, with the neutral good, easy placement of the test block, etc., for the placement test, par.

3 leg hinge structure, from the legs and allows the instrument to maintain a 30 ° angle on the platform, put away when not in use, easy to place.

4 par as the standard length of the instrument for the correction of equipment, positioning the dial gauge location.



Four. Using the operating



(1) 3 hours prior to use instruments and standard rod placed in the measurement of 20 ° C ± 2 ° C indoor. Support from the outrigger.

Measurement using the standard rod and shelf board with V-shaped slot correction length, unscrew the dial indicator set screws, adjust the dial gauge position, the measuring head and face touch par ball head, tighten the set screws , fixed a dial indicator. Clear dial indicator out of the par.

Concrete specimens placed on a similar par.

Concrete specimens of production, maintenance, measurement, calculation according to standard GB 50119-2003 relevant provisions of the Appendix of the technical specifications of concrete admixtures.
