    DESCRIPTION OF MAIN PARTS Chapter 1 - DESCRIPTION OF MAIN PARTS Thanks to the extreme flexibility of the MBG bore gauge, it is possible to achieve the configuration that is most suitable to any individual requirement. The graphic representation below identifies the main parts of the bore gauge, which will be analyzed in detail further on.

  • Page 6: Chapter 2. Assembly And Zero-Setting Of Indicator

    PENCIL PROBE The operations sequence varies according to the model purchased: a) Bore gauge WITH Marposs pencil probe (or compatible) mechanically installed and zero set (follow SET-UP A procedure) b) Bore gauge WITHOUT pencil probe installed (follow SET-UP B procedure) SET-UP A 1.

    ZERO SETTING OF INDICATOR MARPOSS MECHANICAL/ELECTRONIC INDICATORS In order to complete the bore gauge, it is necessary to assemble the display dial and to follow the quick set-up procedure described below, which is suitable only for indicators with Marposs characteristics.

  • Page 9: Non-Marposs Indicators

    QUICK DIGIT: Push the RESET button to zero the indicator. NON-MARPOSS INDICATORS Many indicator models are available on the market, so it is difficult to determine a set- up procedure that can meet all needs. Table 1 shows the maximum indicator specifications with which the procedure described above can be followed.
