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.
