CONDUCTANCE UNITS . . . . . . . . . . . . . . . .
We
use the international unit
of
conductance, the siemen = S =
1/0.
Another unit
of
conductance
is

RELATIVE REFERENCE
An input applied when the RELATIVE button is depressed
to
the
ON
position is held
as
"O"
reference point. Subsequent readings indicate
the deviation
(±)
from this point. (Note: REL annunciator indicates
when this mode is enabled)
RELATIVE ACCURACY
Error will not exceed the sum
of
the errors
