Application
The 5686 thermometer is classified as a primary standard. A primary standard is defined in
terms of transfer of the ITS-90 from a standards laboratory to a customer's laboratory. Primary
standards are calibrated in a standards lab using known intrinsic values. The SPRTs are designed
to meet the National Voluntary Laboratory Accreditation's (NVLAP) Level I Accuracy Class.
Calibration
In order for any instrument to be used as a standard it must be calibrated. The SPRT may be
purchased calibrated or non-calibrated. Fluke Calibration has the capability of performing fixed
point calibration, or comparison calibrations traceable to NIST.
Recalibration
The recalibration of the SPRT should be scheduled according to the user's company Quality
Assurance requirements. Normally, an SPRT is recalibrated annually. Fluke Calibration has the

Extreme care must be taken in shipping an SPRT. Place the thermometer in the factory provided
protective storage case. Be sure the case is latched securely. Place the protective case in the
original manufacturer's wooden shipping crate or wooden crate with similar dimensions. Place
soft insulation on all sides of the crate to cushion the SPRT against mechanical shocks. The cover
of the crate should be attached with screws. We recommend that you label the crate as extremely
fragile. Whether the thermometer is returned for repair or warranty, please include a letter
containing the following information:
• Description of the faulty operation and circumstances of failure.
