457 -=== Process ===
458 -
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.
460 -
461 -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.
462 -
463 -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:
464 -
465 -* sine_5V_30s generates a 1 Hz sine wave with 5 V amplitude lasting 30 seconds.
466 -* step_0V_to_5V_15s generates a 0 V signal for 15 seconds followed by a positive 5 V step function lasting 15 seconds.
467 -* prb 1V 20ms 10min generates a 10 minute PRB sequence using 20 ms pulses and 1 V amplitude.
468 -* prb 1V 5s 150min generates a 2.5 hour PRB sequence using 5 second pulses and 1 V amplitude.
469 -* prb 2V 5s 8hr generates an 8 hour PRB sequence using 5 s pulses and 2 V amplitude.
470 -
471 -=== Procedure ===
472 -
473 -1. Log-in to the Centaur Web Interface and use the Admin credentials
474 -1. Navigate to the Health page and verify that the sensor is properly levelled and recognised by its serial number.
475 -1. To configure the calibration parameters, navigate to the Waveform page.
476 -1. From the Calibration panel at the top page, select Type from the drop-down list and  choose Sine.
477 -1. For the CTR4 series models, additional option to select between Voltage or Current is available.
478 -1. Click on the Configure button to access the calibration dialog box for the selected Playback.
479 -1. Configure the signal characteristics by selecting 5V, 30 sec with gain of 1.
480 -1. Configure the padding before and after the calibration signal, enter 5 seconds.
481 -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.
482 -1. Click OK button to close the dialog box and save the settings.
483 -1. 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.
484 -1. 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.
485 -1. Click on the pause button on the bottom of the page to stop the live stream and use the arrows to centre the sine signal response. Note that the screen waveform will turn Blue and the stream will freeze. Avoid capturing live streaming signal!
486 -1. Once the response signal is cantered, perform a screen-capture “Print Screen” button or use “Snippet” tool and save the captured image locally. In the nametag, include a Serial number, date and sensor type.
487 -1. Archive and back-up the file.
