5.1.10.3 Calibration
Read More! See Self-Calibration
(p. 295).
The CR3000 uses an internal voltage reference to routinely calibrate itself.
Campbell Scientific recommends factory recalibration every two years. If
calibration services are required, refer to the section entitled Assistance
(p. 5)
at the
front of this manual.
5.1.10.4 Internal Battery
Caution Misuse or improper installation of the 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, nor expose
contents to water. Dispose of spent lithium batteries properly.
The CR3000 contains a lithium battery that operates the clock and SRAM when
the CR3000 is not externally powered. In a CR3000 stored at room temperature,
the lithium battery should last approximately 3 years (less at temperature
extremes). If the CR3000 is continuously powered by 12 Vdc, the lithium cell
should last much longer. Lithium battery voltage can be monitored from the
CR3000 Status table. Operating range of the battery is approximately 2.7 to 3.6
Vdc. Replace the battery as directed in Replacing the Internal Battery
(p. 421)
when
the voltage is below 2.7 Vdc.

the appendix Software
(p. 571).
• PC200W Starter Software is available at no charge at www.campbellsci.com.
It supports a transparent RS-232 connection between PC and CR3000, and
includes Short Cut for creating CR3000 programs. Tools for setting the
datalogger clock, sending programs, monitoring sensors, and on-site viewing
and collection of data are also included.
• PC400 Datalogger Support Software supports a variety of telecommunication
options, manual data collection, and data monitoring displays. Short Cut and
CRBasic Editor are included for creating CR3000 programs. PC400 does not
support complex communication options, such as phone-to-RF, PakBus®
routing, or scheduled data collection.
• LoggerNet Datalogger Support Software supports combined
telecommunication options, customized data-monitoring displays, and
scheduled data collection. It includes Short Cut and CRBasic Editor for
creating CR3000 programs. It also includes tools for configuring, trouble-
shooting, and managing datalogger networks. LoggerNet Admin and
LoggerNet Remote are available for more demanding applications.
• LNLINUX Linux-based LoggerNet Server with LoggerNet Remote provides a
solution for those who want to run the LoggerNet server in a Linux
environment. The package includes a Linux version of the LoggerNet server
and a Windows version of LoggerNet Remote. The Windows-based client
