Realtime Data Loop – Up Button
Press the Up button from the Home screen to view real time sensor data.

Sensor Signal

The first screen shows sensor output in real units in real time. These values are calculated
based on the sensor and gain settings. Tap or shake the sensor to see the numbers change.

E: -0.0439408 mm/s
N: 0.0360011 mm/s
Z: -0.0011021 mm/s
If you have a 4-channel Gecko, the date and time line will not be shown, with channel O
appearing at the bottom with its live sensor units values shown as per the settings.

Vector Sum

The next screen Up shows the live vector sum of the 3D sensor, and holds the peak value.
For 4-channel models, the live data from channel O is shown and its peak (max) value held.
3D 0.1234567 mm/s
max 11.1234567 mm/s
1D 80.0360011 dB
max 101.0011021 dB

Raw Signal

Pressing Up again will display the raw numbers from the ADC in real time. The values
shown are up to ±8,388,608 counts, which represents a signed 24-bit number.

Another feature of this screen is the ability to view the STA/LTA ratio in real time. The value
at the end of each line is the ratio of the average signal in the short term divided by the
average signal in the long term. When nothing much is happening, this value will sit around
1.0, but a short burst of anomalous signal will increase number. This number may assist
you in determining at what level to set your STA/LTA trigger threshold.
Note: The STA/LTA value will only display if STA/LTA triggering is enabled.
Pressing the Right button on this screen will prompt you to
press the Right button again to reset the zero level. The
Zero Level is set based on the average signal level over the
next 2 seconds.
Pressing the Right button on this screen will prompt you to
press the Right button again to clear the peak values.
Pressing the Right button will prompt you to do so again to
confirm a reset of the zero level. If you have a 4-channel
0.6
Gecko, the date and time line will not be shown, with
0.8
channel O appearing at the bottom.
