1 The sensor generally limits the actual temperature range. Temperature accuracy specifications do not include sensor accuracy. Thermis-
tor temperature accuracy assumes a 10k
Ω sensor. Thermocouple accuracy is with internal reference junction compensation; accuracy is
improved with external reference junction compensation. Thermocouple temperature accuracies are given for external reference junction
compensation and internal reference junction compensation, respectively.
2 Measurement accuracy specifications apply within the operating temperature range and assume 4-sample averaging and 4 lead wires for
PRTs. With 3-wire RTDs add 0.05
Ω to the measurement accuracy plus the maximum possible difference between the resistances of the
lead wires.
3 Actual resolution can be set greater than typical resolution, but the added digits (0.0001 max.) may not be meaningful to the measurement.
3.2 Environmental Conditions
Although the instrument has been designed for optimum durability and trou-
ble-free operation, it must be handled with care. The instrument should not be
operated in an excessively dusty, dirty, or wet environment. Maintenance and
cleaning recommendations can be found in the Maintenance section of this
manual.
For full accuracy, operate the instrument in ambient temperatures between
16–30°C (61–86°F). The battery may not charge properly at temperatures
above 30°C. Do not operate the instrument in an environment colder than 5°C
(41°F) or warmer than 40°C (104°F).
The instrument operates safely under the following conditions:
• Ambient temperature range: absolute 5–40°C (41–104°F) [full accuracy
16–30°C (61–86°F)]
• Ambient relative humidity: maximum 80% for temperature <31°C, de-
creasing linearly to 50% at 40°C
• Pressure: 75 kPa–106 kPa
• Vibration should be minimized
• Altitude less than 2,000 meters
• Indoor use only
