7.14.1 Temperature Accuracy
(Temperature scales selectable between IPTS-68 and ITS-90)
NOTE:
To calculate the Model 9100's accuracy in
°
F (Fahrenheit)
or K (Kelvin) proceed as folows:-
1.
Convert the temperature in
°
F or K to
°
C using one of
the following formulae as appropriate:
°
C = K - 273
°
C = (
°
F - 32) x 5

2.
Read the Model 9100's accuracy (
±∆
°
C
) at this
°
C temperature from the accuracy table.
3.
Convert
∆
°
C
back to
∆
°
F
or
∆

using one of the following
formulae as appropriate:
