Every 10 seconds an array of readings will display. For example:
2007,348,1217,32,3.11,23.50,-9149.485,21.6,1
*2007,348,1217,40,3.11,23.59,-9149.782,21.6,2
*2007,348,1217,50,3.11,23.67,-9149.659,21.6,3
2007,348,1218,0,3.11,23.41,-9149.812,21.6,4
2007,348,1218,10,3.11,23.19,-9149.694,21.6,5
Each line displayed represents an array of data, one set of readings taken at that interval. The
seventh value in each line represents the gauge reading of the transducer.
See Appendix D, “Sample Data Files” for more information on the array format.

The transducer must be positioned to determine a zero reading. Follow the instructions in
the Piezometer Instruction Manual for saturating the filter and lowering into the well. Let the
transducer come to thermal equilibrium by leaving it immersed in the water for 15-20 minutes. If
absolute depth of water is desired, position the transducer just above the water level. Note the
displayed reading in the array. If change (delta) in water level is desired, note the reading
displayed with the transducer left at its immersed location.
