Either resistance diffusion on the
S
pole may be excessively high, or there
is a disconnection nearby. Check the installation to correct the problem.
In both cases, if the problem is being caused by excessive resistance, wa-
tering the rods or inserting several interconnected rods may reduce the
resistance, allowing measurements to take place correctly.
8.4. Excessively high soil resistivity
If soil resistivity is excessively high (above 50k
Ω
m), and therefore beyond
the equipment range, the following message will appear (upper line):
# > 50k@m
4_Pole a= 3m
9. Exporting data to the computer
To transfer data from the
G-TEST
memory to a computer, use the commu-
nications cable supplied with the accessories to connect the equipment and
the computer's
RS-232
ports.
At Windows START menu, select “Programs”, “Accessories”, “Communica-
tion” and start the “Hyper Terminal”. To create a new connection, choose a
name and an icon, and click “OK”. On the next window, select the correct
COM port. After clicking “OK” again, fill in the following data in that exact
order:
4800
,
8
,
None
,
1
,
None
.
The computer is now correctly configured to receive data from the equip-
ment. Press the
MEM
key and the
G-TEST
will send all stored data to the
computer, while the display shows the following message:
Sending Data
Wait ...
Memory data will then be available to visualization and archiving in the
computer.
