Precautions

The CR300 series are multipurpose, compact, low-cost measurement and
control dataloggers. These entry level dataloggers, with their rich instruction
sets, can measure most hydrological, meteorological, environmental and
industrial sensors. They can concentrate data, making it available over varied
networks, and deliver it using your preferred protocol. The CR300 series also
performs automated on-site or remote decision making for control and mobile-
to-mobile communications. This manual provides a detailed look at the CR300
series measurement and control dataloggers and discusses the steps necessary
to begin using it in your application.
Throughout this manual, any reference to the CR300 also applies to every
CR300-series datalogger, unless specifically noted.
READ AND UNDERSTAND the
DANGER: Fire, explosion, and severe-burn hazard. Misuse or improper
installation of the internal lithium battery can cause severe injury. 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.
WARNING:
• Protect from overvoltage
Protect from water
•
Protect from ESD (electrostatic discharge)
•
CAUTION: Disuse accelerates depletion of the internal battery, which
maintains the clock. The internal battery will be depleted in six years or less if
a CR300 remains unpowered. When the CR300 is continuously used, the
internal battery may last up to 10 or more years. See Section 8.3, Internal
Lithium Battery , for more information.
(p. 52)
IMPORTANT: Maintain a level of calibration appropriate to the application.
Campbell Scientific recommends factory recalibration of the CR300 every
three years.
