Uses the powered-up clock for timing. Once the initial 24-hour period has elapsed it is stored in a 14-day
buffer. This is an array from 0…13 at testpoint 732; with 732, 0 being the current day; 732, 1 the previous
day; and so on.
As each day is stored, the Pump Off Count for that 24-hour period is stored in testpoint 731. The array is
indexed with value in testpoint 730. With this set up you can access parameters 234 and 235 to view the
data, and then set parameters 236 and 237 to testpoint 730 to change the day.
The elapsed time for the current day is shown in testpoint 728. The strokes per hour for the past 24 hours are
shown at testpoint 733. This array goes from 0…23.
