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