  • Page 8: Symbols

    Instruction manual for MH & MH+M Apart from particular features for each type of displacement and measurement process, the software provided with all height gauges is the same, which allows an experienced user of manual height gauges to easily use an automatic height gauge (and vice versa). 1.6 Symbols Several different types of symbols are used in this manual.

  • Page 9: Presentation

    PRESENTATION 2.1 General description The MICRO-HITE 2016 height gauge range is different from any other height gauge as it offers an exceptional performance as well as intuitive and easy use. This autonomous measuring instrument is designed for measuring lengths such as external, internal, step, height or depth dimensions as well as distances.

  • Page 11: Instrument Base

    Instruction manual for MH & MH+M 2.2 Instrument base The base is chemically nickel-plated in order to make it very resistant to corrosion. Its lower face, which has been machined to ensure that is rigorously flat, includes three finely-machined support lugs (air bearings) that guarantee the stability of the height gauge. These lugs form a large surface so that any grooves or other similar irregularities on the granite table can be easily cleared.

    The perpendicularity of each instrument is adjusted mechanically in the factory using a patented TESA system, which makes it possible to use it for a reliable and quick control of perpendicularity. The height gauge is adjusted for frontal as well as lateral perpendicularity...

  • Page 13: Rotary Control Handle

    Instruction manual for MH & MH+M 2.5 Rotary control On the MICRO-HITE+M models, a rotary control handle (FEEL&MOOVE patented system) is handle located close to the instrument base. It serves for guiding the instrument when it is moved on the air cushion and for starting the fast displacement of the probe as well as for triggering all main measuring functions (up or down probing, bore or shaft measurement).
  • Page 14 Instruction manual for MH & MH+M In general, the following measuring functions can be executed directly via this rotary control handle, without the need to select the key on the keyboard of the control panel: Definition of actions Moving up Turning the rotary control handle clockwise will move the probe up.

Bore measurement Activating the rotary control handle twice in the same direction allows bore measurement with detection of the culmination point. • When rotating clockwise, the measurement will start with probing the upper point of the bore.

  • Page 16: Electric Power Supply

    The height gauge features an optoelectronic measuring system digitally capturing the system measured length, which is also called measurand (TESA patent). The glass scale with both incremental graduations and a reference mark serve as material measure. According to a principle of reflection, the scale is scanned by a sensor with no mechanical contact. The measuring signal is then transmitted to the control panel.
  • Page 17 Instruction manual for MH & MH+M On the manual MICRO-HITE, the probing force (and therefore the position of the probe on the measuring carriage) is visible through a coloured bar on the right side of the screen. At any moment, when the probe comes in contact with the workpiece to be measured, this bar is activated and changes its colour according to the applied pressure.

  • Page 18: Control Panel

    Instruction manual for MH & MH+M 2.10 Control panel The control panel has been developed as ergonomic and intuitive as possible. Its keyboard is separated in 4 different zones each focusing on particular actions.

    12 PRINCIPLES OF MEASUREMENT 12.1 Generality Before using the MICRO-HITE or MICRO-HITE+M height gauge, it is important to remember that the way in which the values are measured is determined by the measurement problem. It is essential, that the user can define the nature of the measurement process according to the application, in order to quickly get reliable results.

Ideally place the strain gauge in the centre of the green zone in order to allow the measuring carriage to move correctly from one side of the culmination point to the other (maintaining the strain gauge always in this green zone).

  • Page 73 Instruction manual for MH & MH+M Note that the value of the culmination point in our example increases from 19.485 to 114.966. The probe is now at a distance of 0.02968 of the culmination height currently in memory (114.966). 7. The next step consists in moving the probe back in order to obtain the smallest difference possible of delta, which means that the probe is at the minimum value or very close to it.

    Instruction manual for MH & MH+M 13 ST1 MODE 13.1 Generality The access to ST1 mode does not require the determination of the probe constant. This has a direct impact on carrying out a measurement sequence. All measurements regarding the same reference have to be carried out by probing in a direction similar to the one chosen when the active reference has been captured.

    Instruction manual for MH & MH+M The ST1 mode can accept several different references. This means that the measurements stored in the memory may not have been taken in the same direction if they are depending on two different references.
