Table 124. REGISTER 6EH, EXT1 TEMP OFFSET (POWER-ON DEFAULT 00H)

Bit

Name

R/W

Description

7–0

Ext1 Temp Offset

R/W

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.

Bit

Name

R/W

Description

7–0

Ext2 Temp Offset

R/W

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.
