Zero Offset Adjustment:
Compensation
for
residual
impedance
and
stray
admittance
of
the
test
fixture
connected to the UNKNOWN
terminals is
automatically
done
by
the
ZERO
OPEN/
SHORT buttons.
Compensation frequencies:

900k, and IMHz
Compensation
at
other
frequencies
is
automatically
done
by
secondary
interpolation.
Maximum Offset Values:

Continuous Memory:
Memorizes all front panel control settings
(except DC BIAS voltage setting), zero offset
adjustment
data,
A
reference values,
and
comparator
limits
(option
002)
