1. EDG Console/Computer
the edg unit contains a computer that applies mathematical
formulas to determine the physical characteristics of the
soil. the computer also contains memory that remains
intact after the edg has been powered off. this memory is
used to save soil Models and Job site data. see appendix
a for information on edg memory capacity. the edg
console has an lcd display which is used to provide visual
information to the user and a keypad that allows the user to
key information into the edg unit.
2. Electric Soil Measurement Sensor
the soil sensor gathers electrical information about the
soil under test and transfers the information to the edg
computer.
3. Dart Template
4. Temperature Probe
When performing edg testing, the temperature probe
should be placed into the soil. the soil temperature is an
important variable in accurate edg testing.
5. Calibration Check Unit
6. Soil Darts
to get electrical data from the soil, 4 soil darts are pounded
into the ground by a hammer. a template is provided
to accurately position the soil darts. the soil darts are
machined by stainless steel and are expected to last many
years.
7. Battery Charger
the Battery charger that is provided with edg will charge
the battery in approximately 12 hours.
