Calibration is the comparison of particular values between a known measuring (the standard) and the under test measuring instrument. Typically, the accuracy of the standard should be ten times of accuracy of the measuring instrument being tested. However, accuracy ratio of 3:1 is acceptable by most standards organizations.

The accuracy of all measuring instruments would degrade over the time. This is normally caused by wear and tear. However, changes in accuracy can also affected by electric shock or mechanical shock as well as the usage of the instruments, manufacturing environment or even removal of the instrument. Depending on the type of the instrument and the environment, accuracy of the instrument may degraded quickly or in long period of time.

When should we calibrate our measuring instrument?

• According to recommendation of the manufacturer.
• Mechanical shock, electrical shock, removal etc.
• Periodicity (annually, quarterly, monthly)

If our measuring instrument does not perform as per manufacturer's specification. What should we do?

Most of calibration service companies provide you just only checking the accuracy of measuring instruments according to the standard values of manufacturer's specification. They do not provide adjustment service when the accuracy is out of the specification. Inaccurate measuring instrument always creates trouble during operating, and requires compensation for error on measurement data. HTT, as one of Nikon's certified service center offer sophisticate adjustment calibration service tuning your measuring instrument to meet Nikon specification

What is the benefit of adjustment calibration?

Besides calibration certificate, adjustment calibration will ensure the standardized   performance and accuracy of our measuring instrument. The calibration service with certified companies will render you cleaning along with maintenance and repairing with genuine parts according to manufacturer's standard. We should realize that improper service of cleaning, maintenance and repairing could adversity affect accuracy and durability of the measuring instrument. 

HTT service engineers provides calibration and maintenance capability according to Nikon's standard.
