Calibrating A Gecko Sma-Hr; Installing The Gecko Tremor - Gecko Compact Product User Manual

Calibrating a Gecko SMA-HR

The Gecko SMA-HR has an in-built calibration procedure whereby the processor sends a 5Hz
sine wave of 1V amplitude to excite the sensor components. By comparing the sensor
response 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 you
performed the calibration to see how the sensor responded. It should look like this:

Installing the Gecko Tremor

You can follow the same installation procedure as the SMA-HR for the Tremor. The main
difference is that the typical application for the Tremor will either be local earthquake
monitoring (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 to
point towards the vibration source which will make the North channel a record of radial
energy, which in turn makes the East channel a record of transverse motion.
