NUSITE NUSEIS Overview • NuSite is part of NuSuite, the NuSeis software package. Figure 1 • • • • • • Figure 1 above shows the NuSite software package as it is used in the overall NuSeis system. NuSite communicates wirelessly over BlueTooth with the NRU recording devices to collect information for charge percentage, voltage, memory, GPS, test results, recording status, error messages, tilt, and more. NuSite transfers this data to NuCentre over WiFi for a comprehensive QC of all deployed NRUs.
NUSITE NUSEIS Handling ❖ While the construction of the NuSeis field equipment is extremely rugged and robust, some of the equipment still contains electronic circuitry that could possibly be damaged by heavy physical shock and abuse. ❖ Handling of all NuSeis equipment should be done in accordance with precautions and instructions described in the NuSeis Manuals. ❖ NRUs should be handled with care. Avoid dropping or throwing the nodes to cause a heavy shock to be translated into the internal electronics.
