Specications are given with an ambient temperature of 23°C (73.4°F). Resistance accuracy and temperature accuracy are subject to the ambient
temperature and may be affected outside the “Full Accuracy” temperature range.
2
The temperature range may be limited by the reference probe connected to the external “Probe” connection of the Metrology Well. Does not include
sensor probe accuracy. It does not include probe uncertainty or probe characterization errors.

The 5614–12–D’s temperature range is 420°C.
2.2 EnvironmentalConditions
Although the instrument has been designed for optimum durability and trouble-free
operation, it must be handled with care. The instrument should not be operated in an
excessively dusty or dirty environment. Maintenance and cleaning recommendations
can be found in the Maintenance section.
●
The instrument operates safely under the following environmental conditions:
