Groundwater Pump Test
'This program example demonstrates the use of multiple scans in a program by running a
'groundwater pump test. Note that Scan() time units of Sec have been changed to mSec for
'this demonstration to allow the program to run its course in a short time. To use this
'program for an actual pump test, change the Scan() instruction mSec arguments to Sec. You
'will also need to put a level measurement in the MeasureLevel subroutine.
'A groundwater pump test requires that water level be measured and recorded
'according to the following schedule:
'Minutes into Test Data-Output Interval

' 0-10 10 seconds
' 10-30 30 seconds
' 30-100 60 seconds
