Step 3 - Using the attached table, find the linear temperature interval (T
LIN1
, T
LIN2
) and then the actual
temperature interval (T
1
, T
2
) for T
LIN
.
Example.
T
LIN
= 15.763 °C,
T
LIN1
= 15.178 °C,
T
LIN2
= 16.321 °C,
T
1
= 14 °C,
T
2
= 15 °C.
Step 4 - Calculate accurate table interpolated temperature T, using linear interpolation within intervals (T
LIN1
,
T
LIN2
) and (T
1
, T
2
).
T = ((T
LIN2
- T
LIN1
) * T
2
- (T
LIN2
- T
LIN
) * (T
2
- T
1
)) / (T
LIN2
- T
LIN1
)
Example:
T
LIN
= 15.763 °C,
T
LIN1
= 15.178 °C,
T
LIN2
= 16.321 °C,
T
1
= 14 °C,
T
2
= 15 °C,
T = 14.512 °C
