459 459  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.
