17.7.4 Formatting drives

CPU, , and USB (module required) drives can be formatted individually. Formatting a drive erases
all files on that drive. If the currently running user program is on the drive to be formatted, the
program will cease running and data associated with the program are erased. Drive formatting is
performed through the data logger support software File Control > Format command.

17.7.5 Full memory reset

Full memory reset occurs when an operating system is sent to the data logger using Device
Configuration Utility or when entering 98765 in the Status table field FullMemReset (see

17.8 Troubleshooting power supplies

Power supply systems may include batteries, charging regulators, and a primary power source
such as solar panels or ac/ac or ac/dc transformers attached to mains power. All components may
need to be checked if the power supply is not functioning properly. Check connections and
check polarity of connections.
Base diagnostic: connect the data logger to a new 12 V battery. (A small 12 V battery carrying a
full charge would be a good thing to carry in your maintenance tool kit.) Ensure correct polarity
of the connection. If the data logger powers up and works, troubleshoot the data logger power
supply.
When diagnosing or adjusting power equipment supplied by Campbell Scientific, it is
recommended you consider:
Battery-voltage test
l
Charging-circuit test (when using an unregulated solar panel)
l
Charging-circuit test (when using a transformer)
l
