The ASSIGN command is also used to access custom EU tables previously
loaded into the specified channels' linearization table area. The
< compensation > parameter is used only if the custom EU is a thermocouple
conversion which needs reference compensation. For custom EU
conversion, the bit positions of the
following meanings:
15 - 7 6
always 0 Custom
Bit 6, Custom: determines whether the EU conversion is standard (as
previously discussed), or custom. Set bit 6 to 1 for custom (40
Bit 5, Reference: when set, specifies that this channel is a custom
temperature conversion that is to be used as the thermocouple reference
junction temperature for all subsequent thermocouple measurements.
Bit 4, Piece Wise: when 1, indicates that the linearization table is a piece
wise conversion table. When 0, indicates the table is linear.
Bit 3-0, Shift Factor: specifies the Shift Factor based on the range the table
was built on. This is the negative-to-positive voltage range that the custom
conversion table covers. The Shift Factor versus voltage range is as follows:
