--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,
--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,
--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.

  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.
--Calibration output signal actions are launched from the **Waveform** page in the Centaur Web interface. A synthetic waveform signal generator allows you to generate sinewave and pseudo-random binary (PRB) signals on demand. User can configure the sine frequency or PRB pulse width, signal duration and amplitude as well as specify lead-in and lead-out silence intervals before and after the calibration waveform. One can also select and play a calibration file containing any other desired digital time series waveform that by uploading it to the Centaur, such as a swept sinewave, step function, random noise, or chained PRB sequence.

  The following sample calibration files are supplied with the Centaur. These files may be used to visually verify functionality and approximate sensitivity of the sensor by inspection of the output waveform:
--* **sine_5V_30s** generates a 1 Hz sine wave with 5 V amplitude lasting 30 seconds.
--* **step_0V_to_5V_15s** generates a 0 V signal for 15 seconds followed by a positive 5 V step function lasting 15 seconds.
--* **prb 1V 20ms 10min** generates a 10 minute PRB sequence using 20 ms pulses and 1 V amplitude.
--* **prb 1V 5s 150min** generates a 2.5 hour PRB sequence using 5 second pulses and 1 V amplitude.
--* **prb 2V 5s 8hr** generates an 8 hour PRB sequence using 5 s pulses and 2 V amplitude.
++* sine_5V_30s generates a 1 Hz sine wave with 5 V amplitude lasting 30 seconds.

 . Configure the padding before and after the calibration signal, enter 5 seconds.

++1. The Duration (s) time can be made shorter or longer as required by user. NOTE, for shorter frequencies a longer duration will be required for the signal to complete its full cycle and to capture the entire waveform on the screen.
 . Click OK button to close the dialog box and save the settings.
 . Click the start calibration button  [[image:1733178329484-829.png]] to begin the process. Approximately 5 seconds of time padding ( as set in Step 8) will past before the sensor responds to the injected signal and display the sine wave feedback response.
 . The calibration will end after 30 seconds (as set in Step 7) or can be terminated manually by pressing the stop button. The calibration will then stop after 5 seconds and any configured lead out silence will be skipped.
