Three wire accuracy is the same if contact
resistance errors are removed by calibration
of instrument plus probe at 0°C. Includes DIN
43760 (ITS-90) conformity, repeatability,
temperature coe cient (18° to 28 °C), time
stability (one year) and errors with up to 50 Ω
of lead resistance (each lead). Excludes probe
errors; however, probe errors around 0°C may
be compensated by an internal adjustment.
