CR3000s may be ordered with an integrated power supply base. Power to a power
supply base is controlled by a manual switch on the right side of the case, below
the keyboard display.
Power connects through the green POWER IN connector on the face of the
CR3000. The positive power lead connects to 12V. The negative lead connects to
G. The connection is internally reverse-polarity protected.
The CR3000 is internally protected against accidental polarity reversal on the
power inputs.

Warning Misuse or improper installation of the internal lithium battery
can cause severe injury. Fire, explosion, and severe burns can result. Do
not recharge, disassemble, heat above 100 °C (212 °F), solder directly to
the cell, incinerate, or expose contents to water. Dispose of spent lithium
batteries properly.
A lithium battery backs up the CR3000 clock, program, and memory.

If the CR3000 datalogger sits near a PC, direct-connect serial communication is
usually the best solution. In the field, direct serial, a data storage device, can be
used during a site visit. A remote comms option (or a combination of comms
options) allows you to collect data from your CR3000 over long distances. It also
allows you to discover system problems early.
A Campbell Scientific sales engineer can help you make a shopping list for any of
these comms options:
•
Standard
o RS-232 serial
