Clock

The instrument clock is maintained during brief disconnections. This time is usually sufficient to change batteries. If the clock is lost, the time will revert to January 2000. In this case, check the power supply and synchronise with the computer again.

USB-C power

The USB-C cable provides power sufficient for configuration or data download. However, the instrument requires an internal power supply to perform sampling.

For deployment estimates specific for your instrument configuration and sampling options:

  • Go to Ruskin and click the Instruments tab

  • Select Simulate…​, find your instrument under Gen 4 > Standard instruments, and click OK

  • Adjust variable parameters under Deployment to match your needs

  • Ruskin autonomy engine will calculate the end date and indicate when your deployment is likely to stop
