Setting the Rate Display Units (rateU)
Rate is displayed in terms of a unit of volume, and a time base. The unit selected will be used with the
time base to establish the rate unit (example: GAL/S when Units is GAL, and time base is seconds).
The custom unit selection (CUST) will require the custom unit to be entered by the user. See Custom
Units Rate Conversion Factor on page 34.
