Why does the voltage measurement UL-N show approx. 115 V?

You get this display when you measure with the 2-pole adapter in the Schukoadapter setting.

• Switch to option 2-pole adapter, then the voltage is displayed correctly.

Background: With the 2-pole adapter, the measurement input for the N conductor is open. Via the internal voltage divider measuring resistors, the voltage is divided from L to PE, so that approx. half the voltage is present at the open N input.
