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 2
1 Dx
+ if the Dx＞0.1.
 : Ae is applied only when the test level is set to 1Vrms.
