Piezo exchange
A piezo-element exchange requires a total disassembly of the digital back and the replacement of the two piezo-elements in the aluminium frame.
Before reassembly of the digital back, additional hardware modifications are conducted if necessary to insure the best possible performance for the specific product.
After a piezo-element calibration and a CCD-sensor calibration, the CCD and the IR-filter are cleaned. The filter is then remounted (or replaced if it has any scratches). For further details, please refer to the descriptions of “piezo calibration” and “CCD cleaning”.
After passing all tests, the back is ready to be returned.
