++Install a known working (and charged) battery into the recorder and turn ON the main power switch, verify that the recorder powers ON correctly.
++(% class="box infomessage" %)

++Unit powering ON is not instant, there may be a 10 to 15 sec delay.
++)))
++
++
++Verify the LCD screen turns on and begins clearly displaying the ANU logo and system parameters correctly once the recorder powers up. Look for signs of flickering, blurring or any other visual artefacts.
++
++With the recorder powered ON, using a multimeter, test the bias voltage on GPS antenna port; the reading should be 3.3V (outer shell is negative and centre pin is positive).
++
++Connect “Test Power Plug” into the sensor port and verify the light is turned on, this indicates the power will be correctly delivered to the sensor.
++
++
++(% class="box infomessage" %)
++(((
++The following step, power feature is not present in LPR200, therefore this step cannot be verified for  LPR recorders.
++)))
++
++== System Test ==
++
++* Verify LCD screen works correctly.
++* Check that the keypad is responsive and functions correctly.
++* Verify recorder has GPS fix acquired and information is displayed.
++* Insert SD card and verify the latching mechanism holds the card and releases it.
++* Verify the SD card is detected and can be erased.
++
++=== System information ===
++
++Record the Firmware version.
++
++In the Menu under “System Information”, verify that the serial number matches what is written on the case.
++
++
++== Functional Test ==
++
++=== Charging ===
++
++Verify the battery is charging (LPR differs from TSAWR, additionally, TSAWRs differ between each other based on firmware version).
++
++Set-up an external power source, by connecting a solar regulator to a power supply  and set voltage to 18V DC. Verify the regulator is supplying the correct voltage of 7.7V and then plug into the “External Power” port of the recorder.
++
++(% class="box infomessage" %)
++(((
++There are two types of solar regulators available. Make sure to not mix them as they supply different Voltages, 7.7V and 13.8V.
++)))
++
++Navigate to “System Information” in the Menu and note the battery icon will have a lightning symbol indicating it’s charging, also observe the state of charge % is increasing under.
++
++=== Sensor Reading ===
++
++Live Seismometer Data is used ONLY for functional verification. It is an indicator that all connections to the sensor and output response is correct.
++
++Place the recorder on flat surface bench/ table and connect the sensor (ensure the sensor is not tilted, shaken or rough-handled). Level the sensor using the bubble as guide. Turn ON the recorder wait until the self-check has completed and the recorder has acquired GPS fix. Set the parameters to read the correct sensor.
++
++To verify the sensor is detected and registering, perform a controlled test is performed by having the person press down on the table with their body weight (similar to performing a slow CPR). The flexing of the table will be detected by the sensor and will be clearly visible on screen. This will verify the sensor-cable and the internal digitizer are working correctly.
++
++(% class="box infomessage" %)
++(((
++If the user requires to verify the sensor or the validity of the recorded data, a power spectral density analysis would need to be performed, see rest of document (link here) for instructions on how to perform this test.
++)))
++
++=== Recording test ===
++
++Insert SD card and erase the content.
++
++Set-up the System Parameters (sensor type and interval frequency).
++
++Ensure the recorder has a GPS Fix.
++
++Select the recording setting in the menu.
++
++
++Ensure to allow sensor data recording of overnight or at least 4 hrs.
++
++Verify the data has recorded correctly by running a power spectral analysis (PSD) script.

++=== Process ===
--words
++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.
++
++=== Procedure ===
++
++1. Log-in to the Centaur Web Interface and use the Admin credentials
++1. Navigate to the Health page and verify that the sensor is properly levelled and recognised by its serial number.
++1. To configure the calibration parameters, navigate to the Waveform page.
++1. From the Calibration panel at the top page, select Type from the drop-down list and  choose Sine.
++1. For the CTR4 series models, additional option to select between Voltage or Current is available.
++1. Click on the Configure button to access the calibration dialog box for the selected Playback.
++1. Configure the signal characteristics by selecting 5V, 30 sec with gain of 1.
++1. 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.
++1. Click OK button to close the dialog box and save the settings.
++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.
++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.
++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!
++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.
++1. Archive and back-up the file.
