Scaling Option and Destination Register Length Options Explained

The source data may be scaled from a 32 bit or 16 bit value from the relay to a 16,12,8,4,or 2, bit scale of the
value which is sent to a destination register. The scaling, minimum and maximum values sent to the destination
register are listed in the table below.

The above table lists the maximum and minimum values reported to a host in the scaled format. Table 5-10
illustrates the value correlation between the scale bit minimum and maximum numbers reported to the host
versus the unscaled values generated by the TPU2000 and 2000R.
