You select individual channel ranges using write words 1 and 2 of
the block transfer write instruction.
Scaling lets you report each channel in actual engineering units.
Scaled values are in integer format.

Note: In thermocouple mode, scaled number has an implied decimal point 1 digit from the right. For example, if reading is
18000, temperature is 1800.0. In millivolt mode, the implied decimal point is to the left of the last 2 digits. For example, if
reading is 2250, actual reading is 22.50mV
