Recalibration
Why recalibrate?
As with any calibration equipment, it is recommended that the XL laser is
periodically recalibrated to give condence that the system:
• is currently still within original specied (or required) performance
• is likely to remain within its specied (or required) performance until its
next recalibration
This is why recalibration of calibration test equipment is a mandatory
requirement of most quality management/assurance systems�
An added benet of periodic calibration is that the inspection Renishaw
carries out when recalibrating your XL laser can reveal any otherwise
unidentied accidental damage. The recalibration procedure includes
general cleaning�
Compared to your investment in the measurement system, staff and
procedures, periodic recalibration is a modest additional cost and could
prevent far more serious and costly problems arising later�
Recalibration periods
The Renishaw recommended recalibration period for an XL laser is 3 years�
NOTE: This is 3 years from sale by Renishaw rather than from factory
calibration date as stated on the calibration certicates supplied with the
new equipment, since the units are stored under controlled conditions by
Renishaw prior to sale�
Renishaw recalibration periods are only a recommendation and are based on
typical use of the equipment in a typical environment� Under such conditions
your XL laser should still be performing within Renishaw’s specication at the
end of this period�
However, there are several factors that may generate the need for more or
less frequent calibrations including:
• Environmental conditions
• Frequency and duration of use
• Harsh treatment of the equipment during storage, transportation or use
• Level of accuracy required by the user
• The requirements of company QA procedures and/or local regulations
Ultimately it is for you to determine the appropriate calibration period
after taking into account your own operational environment and
performance requirements�
