Connecting the S12-MKII-50 Data Logger
The data logger incorporates a USB connector at one end for powering the water
level and weight sensors and logging the measured data via a PC. The USB lead
supplied should be connected from the socket on the data logger to the USB port on
a suitable computer running the Armfield S12-MKII-50 Software. The basic operation
of the S12-MKII-50 can be confirmed by referring to the Operating the PC Software
section.
Operating the PC Software
Details about operating the software can be obtained by choosing the ‘Help’ tab in
the top right hand corner of the screen as shown below:
The software is split into three parts to suit the different exercises associated with
S12-MKII.
Part 1 of the software is used to determine the Sand Factor (voidage) of the sand
used in the sand tank.
Part 2 of the software is used for continuous logging of the Outflow from the
collecting tank and any change in mass, allowing rainfall hydrographs, sediment yield
etc to be monitored continuously throughout an exercise. The software also allows all
relevant settings to be manually entered for future reference.
By choosing Rainfall in Experiment type, data relating to Mass change is not
recorded allowing Height and Flowrate only to be recorded. Choosing Sediment
Transport in Experiment type allows Mass of Sand and Sediment Yield to be
recorded in addition to the Height and Flowrate.
Part 3 of the software is used for manual entry of results obtained from the bank of
manometer tubes allowing water table profiles, draw-down at wells etc to be recorded
and graphically presented. The software also allows all relevant settings to be
manually entered for future reference.
