TO с соответствующим передаточным отношением при установленных значени х аир определ ют значение измер емого диаметра по разнице перемещений конических игл измерительного стержн .TO with the appropriate gear ratio at the set values of air, determines the value of the measured diameter by the difference of displacements of the tapered needles of the measuring rod.

С целью упрощени  определени  разности перемещений конических игл измерительного стержн  корпуса 4 и 8 устройства взаимно закрепл ютс  в положении, котором одна игла установлена в отверстии и ее корпус упираетс  в торец детали, а втора  игла и ее корпус наход тс  в исходном положении. В этом случае при введении второй иглы в отверстие отсчет по щкале первой иглы дает значение разницы перемещений конических игл.In order to simplify the determination of the difference in the displacements of the tapered needles of the measuring rod of the device body 4 and 8, they are mutually fixed in a position whereby one needle is installed in the hole and its case abuts against the end of the part, and the second needle and its case are in the initial position. In this case, with the introduction of the second needle into the hole, the reading on the scar of the first needle gives the value of the difference in displacement of the tapered needles.
