The CR3000 uses an internal voltage reference to routinely calibrate itself.
Campbell Scientific recommends factory recalibration as specified in
Specifications
(p. 95).
If calibration services are required, see Assistance
(p. 5).

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.
The CR3000 contains a lithium battery that operates the clock and powers SRAM
when the CR3000 is not externally powered. Voltage of the battery is monitored
from the CR3000 Status table (LithiumBattery
(p. 584))
. Replace the battery as
directed in Internal Battery — Details
(p. 497).
The lithium battery is not rechargeable. Its design is one of the safest available
and uses lithium thionyl chloride technology. Maximum discharge current is
limited to a few mA. It is protected from discharging excessive current to the
internal circuits (there is no direct path outside) with a 100 ohm resistor. The
design is UL listed. See:

Datalogger support software handles communication between a computer or
device and the CR3000. A wide array of software are available, but the following
are the most commonly used:
•
Short Cut Program Generator for Windows (SCWin) — Generates
simple CRBasic programs without the need to learn the CRBasic
programming language
•
PC200W Datalogger Starter Software for Windows — Supports only
direct serial connection to the CR3000 with hardwire or select Campbell
Scientific radios. It supports sending a CRBasic program, data collection,
and setting the CR3000 clock; available at no charge at
