3-1. Measurement Range
With 100Ω source resistance, there are five ranges: 31.6Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ.
With 30Ω source resistance, there are six ranges: 10Ω, 30Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ.
The effective measurement range is listed as below.
3-2. Accuracy
3-2-1. Accuracy of │Z│, L, C，R, X
The accuracy (Ae) of │Z│，L，C，R，X is shown as below:
[%]
A: Basic measurement accuracy (Refer to Fig.3-1)
K
a
: Impedance scaling factor (Refer to table 3-4), impedance <500Ω
K
b
: Impedance scaling factor (Refer to table 3-4), impedance >500Ω
K
c
: Temperature factor (Refer to table 3-5)
K
f
: Calibration interpolation factor (Refer to table 4-6)
K
L
: Cable length factor (Refer to table 4-7)
Note: Choose only Ka or Kb, depending on resistance value. For others, input zero.
Condition for L, C, X accuracy: Dx (D measured value)≤0.1
Condition for R accuracy: Qx (Q measured value)≤0.1
When Dx≥0.1, for L, C and X, its accuracy factor Ae shall be multiplied by
When Qx≥0.1, for R, its accuracy factor Ae shall be multiplied by
3-2-2. Accuracy of D
The accuracy De of D is calculated according to:
The above formula is valid only when Dx≤0.1.
When Dx >0.1, De shall be multiplied by
