1
Specifications 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.
3
The 5614–12–D's temperature range is 420°C.

Environmental Conditions

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 of the Users Guide.
The instrument operates safely under the following environmental conditions:
•
temperature range: 5–40°C (41–104°F)
•
ambient relative humidity: maximum 80% for temperature <31°C, decreasing linearly to
50% at 40°C
•
pressure: 75kPa–106kPa
•
mains voltage: within ±10% of nominal
•
vibrations in the calibration environment should be minimized
