Note:
1. The accuracy applies when the test level is set to 1Vrms.
2. Ae multiplies 1.25 when the test level is set to 250mVrms.
3. Ae multiplies 1.50 when the test level is set to 50mVrms.
4. When measuring L and C, multiply Ae by (1 + Dx2)1/2
if the Dx>0.1.
(*): Ae is applied only when the test level is set to 1Vrms.

ESRAe = ±Xx·Ae/100 = ±1.59Ω
D Accuracy
DAe = ±Ae/100
DAe = Ae of D measurement value
Accuracy applies when Dx (measured D value) ≤0.1

Q Accuracy
QAe = ±(Qx2·De)/(1-/+(Qx·De))
QAe = Ae of Q measurement value

Then
|Zx| = 2·π·ƒ·Lx = 2·π·103·10-3
= 6.283Ω
Refer to the accuracy table, get
LAe=±0.5%,
De = ±Ae/100 = ±0.005
If measured Qx = 20
Then
QAe = ±(Qx2·De)/(1-/+(Qx·De))
= ±2/(1-/+0.1)
θ Accuracy
θAe = 180/π·Ae/100
Example:
Test Condition:
| Frequency: |
1KHz |
| Level: |
1Vrms |
| DUT: |
