This register contains the offset value for the external 1 temperature channel. A twos
complement number can be written to this register, which is then added to the
measured result before it is stored or compared to limits. In this way, a sort of
one−point calibration can be done whereby the whole transfer function of the channel
can be moved up or down. From a software point of view, this may be a very simple
method to vary the characteristics of the measurement channel if the thermal
characteristics change for any reason (for instance from one chassis to another), if the
measurement point is moved, if a plug−in card is inserted or removed, and so on.
