Use of machine tools in industry increases with short time for manufacture of work parts, smooth part surfaces, accurate and constantly same level of accuracy. Regular reference taking operation is conducted at machine tools in order to be able to continue works with same sensitivity and said operation is performed by means of comparator (K).
In the related art comparators (K) are able to control if surfaces are parallel to each other, axis are of same alignment and accurate machine parts measurement and deviation.
Use of comparators (K) for longer time causes some problems. Particularly, imposing too much load arising from misuse shortens life of comparator (K). Distance adjustment bar or reference surface on the distance adjustment bar gets worn because of continuous contact of machine operation head. Wearing of distance adjustment bar by time or failure thereof result in taking wrong reference and initially taken reference value change by time and therefore errors may occur. As a result, replacement of reference surface after certain use is necessary. In addition to all of them, distance adjustment bar is without protection against strokes coming from outside and also thread problems may be experienced.
Another experienced problem is the high repair and maintenance costs. The time needed to resume use of failing comparators (K) is long and spare parts are expensive. For those reasons, most of the failing comparators (K) are discarded without repairing. Adjustment circle around comparator timer may also go out of order during shipment. Figure 5 shows general view of comparator (K) used in current related art for reference purposes.
As a result, due to above described negativities and deficiencies it has been necessary to make novelty and development in the related art. Purpose of the Invention

Reference metering mechanism (R) is adjusted according to a start measurement and the equipment such as blade etc. to be measured is compared according to such measurement and it is checked if differences exceed tolerance limit. Height of reference metering mechanism (R) from ground is kept constant at a certain amount. Where machine tool equipment is to take reference, measurement is taken by touching onto equipment reference surface (213).

• Reference surface (213) of metering apparatus (200) is contacted from bottom to upper body (1 10) of calibration main board (100), • Measurement is conducted by shortening of distance bar (212) in direction A downward and measured value is read from timer (21 1 ).
Reference metering apparatus (R) working principle is as follows.
At first stage, metering apparatus (200) is placed inside calibration main board (100). During that time metering timer (21 1 ) conducts metering by means of moving distance adjustment bar (212) and reference length (X) measurement is achieved. At stage two, pressure is provided onto reference surface (213) of the equipment. During that time distance adjustment bar (212) moves downward (in direction A) and provides conduct of measurement by metering timer (21 1 ). The obtained length measurement is compared to reference length (X) measurement.
