*) The measurement uncertainty in overrange is not specified.

**) Voltages > 1200 V only intended for the purpose of transient monitoring, not as a permanent measurement voltage, channel measures up to the technical FSV

***) In ±1200 V with Extended Overrange, Legacy corresponds to 0x007FFFFF ~ 1200 V, but in contrast to the other legacy modes, overrange is also measured up to the specified maximum value, see the following diagram

Note: In Extended Range Mode the Underrange/Overrange display in the PDO status has the character of an information/warning when the nominal measuring range is exceeded, i.e. no Error is displayed in the PDO status and LED. If the technical measuring range is also exceeded, Error = TRUE is also displayed. The detection limit for Underrange/Overrange Error can be set in the CoE.

In Legacy Range mode, an Underrange/Overrange event also leads to an Error in the PDO status.
