Calibration
Why is calibration service so important?
Presently, quality control is being promoted in production facilities of all industries, utilising a standard object or instrument for the production technology involved. For measuring instruments, increasingly high levels of measurement accuracy and inter-change ability are being required.
Inspection and calibration service is installed to the Konica Minolta service system to give the customer the highest possible security that his Konica Minolta Spectrophotometer shows correct readings. Also in ISO 9000 it is pointed out that quality control systems must be maintained in a specified interval. Companies which are certified by ISO 9000 need a proper inspection and certification of the used measuring instruments. The certificate must show the inspection data and the traceable standards which were used to capture this data. For Konica Minolta spectrophotometers, all this data is included in our certificate form.
What is the recommended calibration level?
To fix a proper interval for inspection or calibration is a rather difficult matter. Some instruments are used in laboratory or R&D environment which is clean and instruments are used for a relatively small quantity of measurements. Other instruments are used for quality control in a production line with harder environmental conditions and thousands of measurements per day.
Konica Minolta recommends a calibration interval of 1 year which is found to be a good compromise for most applications. For users of spectrophotometers, Konica Minolta developed an additional tool to roughly check the instrument's performance. The "Easy Spectro Checker 95" utilises a green BCRA colour tile for a daily check of the instrument. Of course, due to only checking one colour, this can be only a rough check. In addition also the BCRA tile may change it's values, thus Konica Minolta recommends an annual calibration even if "Easy Spectro Checker 95" is used.
