Scaling Ranges
The maximum range of the scaling values is +9999 BCD or +32767 binary.
These values must be entered in the format selected in word 2, bit 08 (10).
If invalid values are entered into the scaling words, the corresponding
input in the BTR data will be zero and the invalid scaling bit will be set.

If scaling and alarms are not selected, the module still requires specific
BTR and BTW file lengths for the number of channels used. Table 4.G
shows the required BTR and BTW file lengths.
