It is **critical** to "lock" these feet in place by spinning the locking disk upwards towards the sensor, as tight as possible. This reduces "wobble" which shows up in both low and high frequency signal. It is also probably a good idea to keep the length of the three feet as small as possible. 29 + 27 27 = Setting up Data Logger = 28 28 29 29 * Install data loggers or recorders compatible with the sensors. 30 - 31 31 * Establish a reliable power source, such as solar panels, batteries, or local grid connection. Use a compass to align solar panels facing north in the southern hemisphere for optimal sunlight exposure. 32 32 * Set up a GPS antenna to provide accurate time synchronization for the seismic data. 33 33 * Ensure the GPS antenna has a clear view of the sky for optimal signal reception. ... ... @@ -64,7 +64,7 @@ 64 64 DO NOT: bury the sensors with anything other than a PVC housing or direct burial.
