32Calibrating a Gecko SMA-HRThe Gecko SMA-HR has an in-built calibration procedure whereby the processor sends a 5Hzsine wave of 1V amplitude to excite the sensor components. By comparing the sensorresponse over time you can check that your sensor is still within specification.After running the calibration routine using the feature discussed earlier in this user manual,open the files from your SD card’s continuous data archive that correspond to the time youperformed the calibration to see how the sensor responded. It should look like this:Installing the Gecko TremorYou can follow the same installation procedure as the SMA-HR for the Tremor. The maindifference is that the typical application for the Tremor will either be local earthquakemonitoring (in which case you would orient the arrow on the lid of the Gecko to point North)or for local blast or vibration monitoring (in which case you may wish to orient the arrow topoint towards the vibration source which will make the North channel a record of radialenergy, which in turn makes the East channel a record of transverse motion. |
