Load Correction (Correcting Values to Match Reference Values)
5.6 Load Correction (Correcting Values to Match
Reference Values)
This section describes how to correct measured values based on a reference sample.
A sample with a known measured value is measured. Then a correction coefcient is calculated
and used to correct future measured values. The correction coefcient can be acquired using up to
ve compensation conditions.
Up to ve sets of correction conditions can be saved.
You can congure the following seven settings (in order) for each set of correction conditions:
1.
Correction
frequency
FREQ (p. 115)
Dene the measurement fre-
quency used to measure and
correct the reference sample.
2.
Correction range
RANGE (p. 115)
Set the range to correct.
3.
Correction signal
level
LEVEL (p. 116)
Set the type and value of the
measurement signal mode to
correct.
4.
DC bias
DC BIAS (p. 117)
Enable or disable DC bias
and set the value.
5.
Parameter type
MODE (p. 117)
Set the parameter to use as
the reference value.
6.
Reference value 1
REF1 (p. 118)
Set the Z/ Cs/ Cp/ Ls/ Lp/ Rs
reference value selected for
the parameter type.
7.
Reference value 2
REF2 (p. 118)
Set the
θ
/ D/ Rs/ Rp/ Q/ X
reference value selected for
the parameter type.
Resets the correction
conditions (p. 119).
The correction coefcient is computed from the reference values of Z and
θ
obtained from the set
values and the actual data acquired from the reference sample at each of the correction frequen-
cies.
Correction coefcient of Z =
(Reference value of Z)
(Actual data of Z)
Correction value of
θ
= (Reference value of
θ
) - (Actual data of
θ
)
The measured values of Z and
θ
are rst compensated using the following equations, and then indi-
vidual parameters from the compensated Z and
θ
values are employed.
Z = (Z before correction) × (Correction coefcient of Z)
θ
= (
θ
before correction) + (Correction value of
θ
)
