14. Allow pump to go to SLEEP.
Data does not write to memory until pump has gone into SLEEP
mode.
Successful single-point calibration will provide an entry in the pump
history that can be viewed using DataTrac 2000 Soft ware (v. 3.59 or
higher). If used with earlier DataTrac 2000 versions, the entry will appear
as an undecipherable code; update DataTrac 2000 Soft ware. If an error
occurs during calibration, the event will not be stored in history.
