16.6 Service and Calibration.
To maintain the specified accuracy of the measurement
results, the instrument must be recalibrated at regular
intervals by either the manufacturer or an authorised
Seaward Service Agent. We recommend a recalibration
period of one year. If a period of greater than 1 year has
elapsed since the last calibration/validation a warning
message will appear on the display every time the unit is
powered up.
