This is especially important as some manufacturers use radio frequencies at the very edge of the permitted band and any drift can cause illegal and inefficient operation.
Calibration is vital to obtain good results from the equipment as well as ensuring compliance with the radio transmission legislation.
Along with the checks on the equipment functions and time delay accuracy, the calibration itself is primarily of the radio telemetry system receivers and transmitters.
Early fault detection can help prevent a breakdown and costly downtime of equipment.
Calibration period runs for 12 months from the date of adjustment. Experience has shown that correlator performance may deteriorate after this time and radio links possibly require adjustment. Vital checks are also made on accelerometer sensor sensitivity, connecting cables and general repairs resulting from a year ‘out in the field’.
