6. If the volt metric circuit (terminal S) shows a
too high resistance value the side message
is displayed.
Check connection of red and green wires as
well as their integrity.
If the problem still exists connect two or
more auxiliary rods in parallel and pour
some water around the rods in order to
make a better volt metric probe (that is the
ground rod connected to the red wire).
7. If the ampere metric circuit (terminal H)
shows a too high resistance value the side
message is displayed.
Check connection of blue and green wires
as well as their integrity.
If the problem still exists connect two or
more auxiliary rods in parallel and pour
some water around the rods in order to
make a better ampere metric probe (that is
the ground rod connected to the blue wire).
8. If the ampere- and volt-metric circuits
(terminal S and H) show a too high
resistance value the side message is
displayed.
Check connection of blue, red and green
wires as well as their integrity.
If the problem still exists connect two or
more auxiliary rods in parallel and pour
some water around the rods in order to
make a better ampere metric probe (that is
the ground rod connected to the blue
wire).repeating the procedure for the volt
metric probe (that is the ground rod
connected to the red wire).
