460 -Sensor calibration allows user to input an electrical test signal into a connected sensor to simulate ground motion. The resulting digitized sensor output can then be analysed to assess various attributes of the sensor, such as basic functionality,
461 -frequency response and/or sensitivity stability over time. For a high-quality broadband sensor, these parameters typically remain stable over time, so that if the sensor initially meets manufacturer’s specifications and has not suffered damage,
462 -then calibration is usually not required. However, calibration can be a useful quality control check if it is suspected that the sensor may be defective or damaged after multiple deployments.

471 471  The Centaur data recorder can generate and output an analog signal using a 16-bit internal digital-to analog converter (DAC). The DAC output is applied to the sensor for calibration purposes via the matching sensor cable. Make sure to use manufacturer cables as the correct signal lines have been connected to the correct pins of the mating connector. The Centaur CTR, CTR2 and CTR3 series models may generate signals of up to ±5 V amplitude, while the Centaur CTR4 series models have an enhanced calibration output.
