Adjusting the pressure
Important!
The pressure is adjusted individually by a ZEISS service engineer during
the initial start-up. After this, the pressure must not be readjusted.
If the required pressure is not indicated, proceed as follows:
• Identify the cause of the decrease or increase of pressure ➤“Faults
during the measuring run” on page 8-3.
• Call a ZEISS service engineer if you cannot find or eliminate the
cause.
Filter units
Several filter combinations are offered for the CMM. The CMM fea-
tures a combination of a fine filter and an extra fine filter as standard
equipment. If the required compressed air quality cannot be main-
tained, additional filters can be installed later. The possible versions
are specified below::
