NOTES: The Table attempts to show the effect of each significant factor which contributes to the overall measure-
ment error. See the enumerated items below for more specific explainations of each column of data.
1. Reference Acc'y based on 0.025% (250ppm) of input voltage span.
2. Linearization Acc'y is based on conformance to NIST Monograph 175 (based on the ITS-90) for
letter-designated thermocouple types, or other industry standards for non letter-designated type T/Cs and all
RTDs.
3. Factory Cal is defined by limits of repeatability in a manufacturing environment of
±
10uV for zero and span
calibrations on thermocouples, as stated or other inputs, and
±
0.15
°
C for thermocouple cold junction
calibrations.
4. The REF + LIN + CAL column represents the total "static" error allowed for an instrument as produced by the
manufacturing process.
5. Deviation Acc'y is derived from a temperature coefficient of .01%/
°
C or
±
100ppm/
°
C expressed in units of the
corresponding range.
6. Resolution on thermocouples and RTDs is derived as a function of the input voltage Range and dV/dT.
