Important: Frequency upgrades require the full adjustments and performance test. The completion of a part of calibration (adjustments and performance tests) does verify the functionality of the option, but does not guarantee that the instrument meets all published specifications. A full calibration is the only way to guarantee the analyzer specifications are being met. The upgrade labor and calibration charges needs to be quoted at the same time of the upgrade kit quotation.
