Programming
Programming the Mini-Diver takes only a few minutes on your computer at the office (Diver-Office / Diver-Office Premium) or in the field (Diver-Pocket Manager). You can enter the:
- monitoring point name,
- sample interval,
- sample method:
- fixed
You can start the Mini-Diver at any time you specify.
Retrieving Data
Data may be recovered by inserting the Mini-Diver in a USB reading unit connected to
- a laptop or PC with Diver-Office / Diver-Office Premium or
- a Pocket-PC running Diver-Pocket Manager or Reader.
Using the Diver Data Cable (DDC) allows you to readout the Mini-Diver without removing it from the monitoring well. The DDC can be connected to:
- a Diver-Mate
- a USB Interface Cable that can be connected to a laptop/PC or Pocket-PC
- a Diver-DCX that can be connected to a SCADA [1] or telemetry system with an SDI-12 connection
The Mini-Diver is supplied with the Diver-Office software package. Diver-Office is easy to use and offers additional features such as a barometric compensation wizard to convert pressure readings into water levels. Diver-Office also includes a calibration wizard for quick and easy conductivity sensor calibration. The data from the Mini-Diver is stored on your computer and can be exported in various formats to be used in a spreadsheet program or database.
