calculated. This Thermal Diode Offset value will be programmed into the new diode 
correction MSR and when added to the Thermal Diode Base value can be used to 
correct temperatures read by diode based temperature sensing devices. 
If the n
trim
 value used to calculate the Thermal Diode Offset differs from the n
trim 
value 
used in a temperature sensing device, the T
error(nf)
 may not be accurate. If desired, the 
Thermal Diode Offset can be adjusted by calculating n
actual 
and then recalculating the 
offset using the actual n
trim
 as defined in the temperature sensor manufacturers' 
datasheet.
The Diode_Base value and n
trim
 used to calculate the Diode_Correction_Offset are 
listed in 
§ §§
Table 31.
