Campbell Scientific CR200/CR200X-series Dataloggers - Manual (Page 159)

Section 17. Care and Maintenance
Temperature and humidity can affect the performance of the CR200(X). The
internal lithium battery must be replaced periodically. Factory replacement is
recommended. Contact Campbell Scientific to obtain an RMA prior to shipping
the CR200(X).
17.1 Temperature Range
The CR200(X) is designed to operate reliably from -40ºC to +50°C in non-
condensing environments.
17.2 Moisture Protection
When humidity tolerances are exceeded and condensation occurs, damage to IC
chips, microprocessor failure, and/or measurement inaccuracies due to
condensation on the various PC board runners may result. Effective humidity
control is the responsibility of the user.
Adequate desiccant should be placed in the instrumentation enclosure to prevent
corrosion on the CR200(X) wiring panel. The desiccant needs to be replaced or
dried out frequently enough to control the humidity.
17.3 Enclosures
Campbell Scientific offers environmental enclosures for housing a CR200(X)
and peripherals. These enclosures are classified as NEMA 4X (watertight, dust-
tight, corrosion-resistant, indoor and outdoor use).
