    Performing a Measurement System Power Budget Analyzing a measurement system power budget is a useful practice to help ensure that a proposed system design will meet the monitoring objectives and reliably deliver data. To aid with this, NexSens has developed a power budget tool which can quickly estimate the expected power performance of systems using the most common NexSens buoy platforms, data logger configurations, and commonly integrated NexSens and third-party sensors for deployment locations throughout the world.

  • Page 74 4. Secondary Power – Any power supplied to an X2 through the secondary pins on a UW-6 plug connector will be registered as Secondary Power. Secondary power is typically only utilized by X2-SDL systems running on internal D-cell batteries. All other systems will return ~0V (as shown), indicating that no secondary power input is present.
  • Page 75 Acceptable values will range from a slight negative percentage (effectively zero) up to ~50%. If humidity is reported to be greater than 50%, the desiccant bag inside the X2-CB should be replaced and the enclosure seal inspected. High humidity can contribute to telemetry problems and, in more extreme cases, damage the logger circuitry.
  • Page 76 As with cell signal strength, the cell status parameter applies to all telemetry types including cellular, radio, Iridium satellite, and Wi-Fi. Values of zero indicate that no errors were observed. If status errors appear frequently and data transmissions are affected, contact NexSens Technology and supply the status error code for troubleshooting.
