Description
7–0
Ext± Temp Offset
R/W
This register contains the offset value for the external ± 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.

Ext2 Temp Offset

This register contains the offset value for the external 2 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.
