Maintaining air needles 3-11
Example
For a Greiner deep well with Micronic capmat M53000, the instrument
operates using a standard needle height.
Ht = 41.4 mm The following is true:
Dw = 37.8 mm 41.4 - 37.8 = 3.6 (is between 2 and 6 mm)
Cd = 3.8 mm Protrusion length = 41.4 - 3.8 - 6.0 - 2.0 = 29.6
Nh = 6.0 mm (standard)
Ac = 2.0 mm (minimum)
A 56-mm air needle is needed.
