The A-TAKT V-7HS is designed to maintain stable calibration for long periods of time and is certified for
six months from the factory. However, changes in calibration are inevitable, due to the effects of aging,
temperature and dirt accumulation. Therefore, for best results, periodic recalibration is recommended.
To maintain the instrument's accuracy, recalibration checks or recalibration is recommended at six-month
intervals. Please consult factory for availability of optional user self-calibration.
